I picked up my boat with my new 200 HP Etec yesterday. I was hoping to test it out today, but there are some thunderstorms hanging around. I'll try to update my findings as soon as the weather breaks.

Sit down, shut up, and hang on. I've got a buddy who has a 192 with a 200 HPDI and it's a 50+ mph rig...with that ETEC, I'm guessing you would beat him in a race....

Ypu probably know this, but oil usage will be 2x during a break in period (some number of hours over a certain rpm) either way it will be minimal. You can buy bulk oil from domo online pretty cheap if you don't have a cheap place near you.

The Viper isn't the one for an ETEC. You should have gootten the Rebel (?) or even gone with a Merc Rev4. You will see much better numbers with either of them. I had a Viper on my 250 and it was terrible. Take it back before you use it, or at least get them to agree to retuen it, if you have the poor reulsts with it that I did.

2 years on my 200HO and still loving it. I would switch to a Rebel prop. You will get much better performance and mileage with it. Keep good gas and run XD100 on the XD50 setting and you won't have any trouble. Enjoy the torque!

When you test it, look at the anti-ventilation plate (erroneously called cavitation plate) to see if its just above the water and not buried when running on plane. It looks like your motor could be raised about 2 or 3 holes for better performance.

You've obviously done your homework by the engine you chose....so you know not to listen to the trolls.
Two things, you will burn quite a bit more oil than normal during the first 10-20 hours, based on useage.
After that they sip oil.....
I second the opinion on the Rebel props.....Good luck with it......as other's have mentioned, it should fly....
HarleyFLHP
06-03-2012, 07:41 AM
Thanks to all of those for the words of wisdom. I know there are Etec haters, and that's ok. Sorry to hear you had bad luck. As far as the oil, I was told that it will use a lot of oil during the break-in, hence the reason for the free gallon of oil. The dealer was a pretty straight up guy. I would recommend the marina to anyone in lower upstate NY. The prop choice was not mine, but I will defiantly look into the Rebel. I'm not a prop expert by any stretch but, what are the differences between the two? Why is one better than the other?
rotorwrench
06-03-2012, 11:11 AM
The Viper is more for lighter boats and a bow lifter, where as the Rebel is more of a pusher prop(larger diameter and more cup) for heavier hulls.
The oil break-in should be 5hrs above 2500rpm on the V-6's.
HarleyFLHP
06-03-2012, 01:13 PM
I think I will run the Viper then ask the marina if they have a Rebel to try. This way I can compare the two.

Just checked mine. Its a viper 14 3/4 x 16. Really I need a 14 to get the full RPM range out of the engine. My hull is probably heavier than yours and has a lot of windage, so you might find you need something different.

I looked at that and was wondering that myself. I checked the cav plate and noticed it is flush with the bottom of the boat. I will run the boat and evaluate the numbers. If needed, I will raise the motor, thanks.

Went out today for a good run. The motor is 5800 @ WOT and the GPS says 45 mph. In tight turns the engine jumps up in RMP's but seems to launch out of the hole like a scalded dog. I will be going back to the marina to swap out the prop for a Rebel. The cavitation plate was at the surface and running near max RPM's, so I don't see any reason to lift the motor any holes. I am amazed at how quiet the motor is. I used to run 43 mph with the old Yamaha 175 and I was a little surprised I didn't see 50 mph with the new motor.

You could also try a 19 Viper to bring down your rims, increase the speed and fuel economy at cruise. The viper may work better than the rebel on that boat and motor combo. The 200 isn't a strong 200. You won't see a big increase in speed over your 175.
Try all of the props you can to see what works best!
HarleyFLHP
06-22-2012, 05:41 PM
Just an update:
I had a 17 Rebel installed and had the motor moved up a hole. The boat seems to run best at this setting. RPM's are around 5500 and top speed is almost 48. I don't think it will get better than this.

Its normal for the prop to ventilate a little in high speed sharp turns. Your goal is always to reach peak RPMs at WOT and at 5800 you are right there.
As a general rule you usually gain 1 MPH for every extra 10 HP added to the boat. So on a 25 HP gain you should have gained 2.5 MPH so you're not far off.
You can play with different props to gain a few MPH at the same RPMs. Also check to make sure the engine isn't too low. That alone will rob a few MPH.
The real benefit will not be the extra 3-5 MPH but the fuel savings, reliability, warranty, quietness and smoothness.
If you wanted to really haul ass you should have dropped a 225 HO on the boat. :grin:

different props = different set up, you may be able to take that 1 hole higher and get 200 RPM - depends on cavatation and if thats an issue. I have a Stilletto and its at 2 1/2" above the hull and I still can't break it loose - just raised it a hole

They sip oil. Depending on your setup and use you could see 75 gallons or more of fuel burned before you use up one gallon of oil.
Of course you could run them for hours on end idling around or even trolling, burn less oil.

Went for a 2-3 hr cruise today. There were 1-2 ft waves and a stiff breeze. The boat cruised nicely at 30 mph and burned approximately 5 gallons of fuel. I am really amazed at the fuel mileage of the Etec and with the Grady hull, I couldn't be happier. After 30 yrs of boating, I feel I have found the perfect blend. My old Yamaha 175 would have used 3x the amount of fuel.

Could you explain?
Tom W Clark
07-18-2012, 07:52 AM
They only moved the motor up one hole. They should have moved it up two holes.
You do not set motor mounting height based on RPM. You set motor mounting height to achieve the best performance with the motor and model of propeller being used. AFTER that is accomplished, you can adjust WOT RPM by selecting a different pitch, if need be.
Just as you improved the performance of your boat by having the motor moved up one hole, there will also be in improvement moving up another hole. If you do not do that, you're leaving performance on the table and wasting fuel.
HarleyFLHP
07-18-2012, 07:56 AM
I agree that you are very knowledgeable on props, but what determines what hole the motor should be mounted? What about in a turn, the prop blowing out because the motor is too high? What happens when you hit large waves and the bow drops and the back of the boat comes out of the water, won't the prop blow out?
Tom W Clark
07-18-2012, 08:06 AM
In this case, no. I actually think the E-TEC 200 could be mounted all the way up on your boat (three holes up) when using the Rebel or Viper but the two holes recommendation is a conservative compromise. That is how I am so certain only one hole up is at least one hole too low.
The dealer should be ashamed of himself for setting that motor all the way down in the first place and I suspect the marginal one hole move was a way to help the situation a bit without making themselves look like fools for the too-low blunder in the first place.
HarleyFLHP
07-18-2012, 08:11 AM
When I spoke with the dealer, he stated if the motor were too high, the prop will blow out in rough seas or tight turns.
Tom W Clark
07-18-2012, 08:11 AM
Again, he is wrong.
Well, strictly speaking he is right, but it is not possible to mount that motor "too high" with the four mounting bolt holes it comes with and the BRP Rebel.
HarleyFLHP
07-18-2012, 08:15 AM
Tom, I am in no way trying to argue with you, but could you explain it to me so I understand? I don't want to go back to the marina and demand that the motor be raised and tell them "Because Tom said so". If I go back with clear rational, the marina, myself, everyone on this forum learns from your knowledge.
Tom W Clark
07-18-2012, 08:46 AM
Ask them to raise it another hole because you would like to enjoy higher top speed, faster acceleration with less bow rise, lighter steering effort, better fuel mileage and reduced draft.
When they object, ask then when the last time they mounted an E-TEC 200 on a Grady White 192 three holes up and had to move it back down. Or even just two holes up. They never have because it is very common for long-time experienced boat dealers to mount outboard motors they same way have been doing so since the 1970s and 1980s.
Propeller technology has come a long way since then and so have outboards. There is no reason on Earth to mount outboards that same way we did back in 1982. Modern propellers have far more grip than anything offered back then, yet dealers persist in doing things that way they always did.
When your boat left the Grady White factory with its original Yamaha outboard, the motor was mounted one hole up. Both Grady White and Yamaha are VERY conservative in their motor rigging so you know there is no excuse for the motor being all the down on the transom in the first place. That was just wrong.
Evinrude E-TECs in this power range have longer midsections that Yamaha outboards so you have to bolt the E-TEC one hole higher just to put the AV plate where it would be if it were a Yamaha or Mercury. So now you are two holes up and you still have the same conservative height of the AV plate as the boat originally had.
Even if the motor were all the way up (three holes up) there is still going to be plenty of motor in the water for normal use. I'm not even sure you would be see ventilation in tight turns or rough water with the motor all the way up, but if you wanted to be conservative, two holes up is the lowest you could possibly justify. And that position is one hole higher than where you are now.
HarleyFLHP
07-18-2012, 08:56 AM
I understand where you are coming from Tom. To be fair to the community, I will document this so others can learn. I will record my numbers with the motor the way it is and raise it one hole and post those numbers so everyone can learn from this. Thank you for your time Tom.
I have a 1990 Tournament 19 with a 200 HP Evinrude Direct Injection 3.3 liter block (I guess this is more equal to the 200HO Etec. I run a 19 inch Viper and can run 55mph GPS at 5800rpm, trimmed out.

You have the 200 HO (big block), mine is the 2.6L block. I was originally going to go with the HO motor, but I felt it was too much weight on the transom (433 lbs Vs 524 lbs). I wanted to make sure the scuppers were clear out of the water. Last checked, I was doing 49 mph on GPS. I will try raising the motor one hole to see if there is a difference.

I was able to have the lake all to myself last week and got the boat out to test the top end. I raised the motor another hole, 3 holes up. WOT RPM was 5850 but the top speed was only 48 mph on GPS. It lost 1 mph, I'm figuring it might have been the wind, not sure. The conditions were good in spite of the wind. Water had a very slight chop and wind was blowing about 7-10 knt. Any ideas Tom? ;?

Skip, was that on the same Grady hull?
So far, the only props I have tried are the 17" Viper and 17" Rebel. I have raised the motor 2 holes so far. The RPM is right about where it should be, so I am thinking this is top speed for the hull. Before I raised the motor another hole, I was seeing about 5300 RPM and about 49 MPH. Something doesn't sound right if I increased the RPM by about 400-500 and did not see an increase in the top end mph. I will reserve judgement on the top speed until I hear from Tom.
My 19 Grady is a 1990 model, so I think the hull might be a little different. Mine has a 200 Evinrude 3.3l DFI and will do 55 mph at 5800 rpm trimmed out with a 19 inch Viper. I would think the small block would be able to rev up to 5400-5500 with a 19 inch Viper trimmed out and certainly get you into the 50-52 mph area.

3.3 is the big block motor. I thought about it, but the weight on the transom might have been a little too much for the scuppers. I'm sure I would have seen 50+ mph with that motor. I had the Viper, but received numerous suggestions on the Rebel.
It might be worth testing with a 19 inch pitch, I think the 17 inch is the limiting factor. As I remember the the big block puts out closer to 218 HP while the small block is right at 200HP. It would seem to me that it's the 18 extra HP that allows mine to rev to 5800, where as the 200 HP the small block puts out would drop the top RPM back to 5400-5500 with a 19 inch pitch. I might not run out and buy one, but if you could borrow a 19 inch for a test, it would eliminate that setup variable.

Before I raised the motor another hole, I was seeing about 5300 RPM and about 49 MPH.
I raised the motor another hole, 3 holes up. WOT RPM was 5850 but the top speed was only 48 mph on GPS
It is good to have data points when trying to figure out what propeller to use. I have trouble accepting the first one, however. For the 17" Viper to hit 49 MPH at only 5300 RPM on the E-TEC 200, the propeller slips calculates to - 6 percent. We sometime see negative calculated propeller slip with some models of propellers, but not with the large tube Viper.
48 MPH at 5850 RPM is much more believable with a calculated propeller slip of about 6 percent, a typical figure for this propeller.
At any rate, the E-TEC 200 has a recommended WOT engine speed range of 4850-5850 RPM, but the optimal range is 5600-5850 RPM.
You are the very top of this range now and could easily afford to loose a couple hundred RPM. I recommend you swap the 17" Viper for an 18" Viper and see how it does. It should bring your RPM down 150-200 RPm and increase your speed and fuel economy.
Lastly, you report you are still using the Viper. It is a 15 1/2 x 17 prop. The Viper would be a 14-3/4" x 17". The 18" also has a 14-3/4" diameter. Are you sure you are not confusing the Viper with the Rebel, which does have a 15-1/2" diameter?

Yes Tom, you are correct, my mistake. I am running the REBEL. which prop do you recommend?

You should try the 15-3/8" x 18" Rebel.

I'll see if the marina has that size to lend.

Were in Ny Did you have this done ? What was the cost? How much for the install?
Going to repower my 17 outrage 11 with a 130 E-tec were should I go on Long Island

George, I used Nick Roberti's marine in Kingston. He has the best prices on Etec's. He also sells and services, Yamaha, Mercury and Honda outboards. Out the door, my motor cost $15k. I sold my old Yamaha and he helped with the sale and loaded it up for the new owner. Real stand up place.
