That is because he's probably thinking the same thing I am--what kind of breakin procedure was browndog using. Two powerheads in 5 hrs, sounds suspicious to me.
Used to sell and service Kaw and Suz motorcycles to work my way through the first year of college. Rebuilt a pile of brand new ones because the NEW owner wouldn't follow the breaking procedure. We finally ended up disconnecting the spedo, and put a couple of hours on them ourselves before giving them to the new owner. Problems nearly disappeared.
Now I'm not saying browndog put most of those 5 hrs on the new motors at WOT, but, based on my prior experience, I'd be asking some questions.
Took delivery of a new Parker with twin Yam F115s. Both motors had 2 hrs on the hour meters when I took delivery. Dealer stated they ran the motors in the tank to make sure everything was A-OK. I smiled and thanked them, cause I knew exactly why they did that.
When you get your motor back, or a new motor,have the mechanic put a vacuum gauge and a piece of clear fuel line on the fuel inlet fitting, just like they show in the service manual and teach in the service schools and seminars. When you run the boat, there should be no air bubbles at any speed and the vacuum should be below 4"Hg on a good boat fuel system. Yamaha has a max of 6"Hg on fuel restrictions. Air bubbles make the fuel froth and the motor runs lean. A restrcition keeps the fuel pumps from delivering enough fuel and again the motor runs lean.
The mechanic should also hook up the fuel pressure gauge and observe it at all speeds. Low fuel pressure, motor runs lean and pistons go boom.
I don't have a Yammy, but a Johnyrude. During the breakin period for my motor, double oil premix at 50/1, plus VRO was required for at least first 10 hours. In the post, I didn't see any mention of double, premix oil. I would think yammies needed the same thing???
Browndog, you wouldnt be trying to sell me a brige in Brooklyn would you?
I have been around outboards for over 50 years and never heard anything like this.
Lets get some facts, how about the name and location of the dealer, serial nos. of the motors, etc. This is an easy story to check out. If it did happen, dont expect it to happen for another 50 yeas.
23' Regulator, 2 200 HP Yamaha HPDI's. Charter and SKA Tournament fishing, Chair of King Mack Tourn. benefits underpriviliged kids in Eastern NC.
The model number of the motor is sx200txra it is on a 23 Sea Hunt boat. I believe it is a standard rotation. I don't know where to find the info for 2.6 or 3.1
I have to check to see what type of dealer they are. I looked on Yamaha's website and they are not a five star dealer. I need to check to see if I was given a new block or A hydrotech rebuild.
I will post this when I talk to the dealer.
serial number
6G6x007830R
This is the number the dealer gave me and said it was the serial number. I checked my paperwork and the number was the same except it did not have the R on the end of the number.
My post was not to bash any motor company I just wanted help with the situation. This was the my first new boat purchase and I was a little frustrated from what happened.I just wanted some advice from other people.
Round2it- still have double oil in the gas tank 50.1
Finman 200
C stanman the story is true, check the serial numbers I am not going to name the dealer until my boat is fixed, I have not bashed anyone yet so I am not going to start now. The boat was bought in Maryland. When the first motor blewup I posted it on another board here the link.The first engine died on April 20
browndog,
People here are so nice and friendly !!!
Almost everyone question's your veracity !!!
Makes you want to stay on Tidalfish.com
I have yet to be called a name on TF, or have my posts questioned. Wish THT was a little less "abrasive". They lose a lot of posters because of it, and they turned me into a "mostly lurker".
Good Luck With the Yammie !!!
See Ya around the River

Browndog.. I am told you can get a bad motor from anyone. I recently re-powered my 25 Parker, with a pair of 225 SS Yamahas. I went to a nearby lake to try to get some hours on them, and I blew the port engine with only 1 hour on it. I have to say that Yamaha really stepped up to the plate cause I had a NEW powerhead and all the parts within 4 days. The mech who repaired my motor was with me when it blew. At the last minute, while putting everything back together, he discovered that the reeds for the top two cylinders had also been damaged, so Yamaha sent the reeds NEXT DAY AIR! I can't believe you're getting the run-around. I only have good things to say about Yamaha. My engines now have 54 hrs on them and they purr like kittens. These are the first Yamahas I have ever owned, in the 30 years I've been boating, and I have all the confidence in the world in them and the company. I hope you keep us posted about how this turns out. good luck....

B D, You're being real level-headed with some of this, I'll give you that.
Bay Bob, I'm starting to see the light. Glad it wasn't on the back of a new Bayliner as well.
Just a thought, maybe a few of you could fill some of us "newbes" in on the history of this board as far as the do's and don'ts of a new member's posts. I suggested to "browndog" on the other board that he may get some issues resolved over here, but instead it looks as if I set him up for a good burn by a few - my mistake. I'd prefer not to repeat that, to myself or others. Maybe being new myself with no credability over here I hadn't the right to suggest someone come here with such a controversal issue. What's the deal?
Capt Stanman, you may of been around OB for over 50 years but the 1st 45 don't count with todays engines. I had a so called bullet proff Suzuki 225 toast a piston at 7.5 hrs. I had a 1990 200 Yamaha toast a crank and rods at 515 hrs 1 year out of warrenty for a line bore problem. Yamaha covered a new powerhead but I had to pay labor. Suzuki picked up the hole works as they should of and had me up in 2 weeks. Both actually both had me up in 2 weeks. Sh!t happenes. These new engines seem to either run flawlessly or blow up promptly, no messing around.
Trouty, I would call a couple members comments pretty abrasive. Lord forbid anyone having a problem with a Yamaha or a Scout. BD is being very level headed and smart to not bash anyone yet. The MFG do monitor these board in seceret. Suzuki does for sure as I had a handfull of print out for the boards showen to me from my dealer folling my engine failier at 7.5 hrs. I only said I was disappointed in the fact they would not give me a new engine. That got all blowen out by 50 other people slamming Suzuki. You would of though I was all those 50 people to my dealer. I guess the internet can work for you or against you in these cases. I would hope it would work 4 you but in my case it was a wash.
brown dog
yoyr engine is a standard rotation 2.6 to see if it is new or a rebuild first thing is that model was not painted from yamaha it would have had the YDC30 process done on it so if it is painted look out.if it is a hydrotech rebuild look at the block under the lift ring between the cylinder heads, give me the number that is stamped there.
BayBob, Don't throw the baby out with the bath water!! A few cynical post are to be expected. I think the vast majority have tried to be helpful. Unfortunately there are some people who are insecure and try to interpret this thread as a bash on Yammies. I always get a kick out of people who own a brand of boat or motor that think any thing negative about the boat or motor is an attack on their manhood. I think it is very obvious from reading BD's posts that the guy is just trying to get his motor fixed. Anyone who thinks Yammies are absolutely perfect and never blow up lives in a dream world. I own Yammies and as an owner am pleased with the way Yamaha and Yamtech are handling the problem.
I don't think seahorses suggestion would really point to anything, since the mechanical fuel pumps feed the vapor canister, which then an electric fuel pump supplies and pressurizes the injector system.
If there is air in the lines, both the mechanical and electric pumps deliver the froth, in fact, they make it worse with their pumping action. That is why Yamaha, in all the training schools and seminars, recommend a thorough check of the boat's fuel system using the vacuum gauge and clear line, especially if it is a repeat failure. It is also published in the Yamaha Marine Technical Guide. Gas mixed with air is like a glass full of foam instead of beer.
If its air in the fuel lines then why does it pick on one piston. Seems like they all would show some signs of a problem. But then I am not sitting here looking at the engine either. You can only do so much from a chair and computer. But I do think the fuel system is something that needs checking and bet the Yamaha rep will figure it out. I just hope BD post what they find.
Trouty,
You do not have an abrasive spot on or in you.
Here is abrasive:
"Browndog, you wouldnt be trying to sell me a brige in Brooklyn would you?
I have been around outboards for over 50 years and never heard anything like this.
Lets get some facts, how about the name and location of the dealer, serial nos. of the motors, etc.
This is an easy story to check out. If it did happen, dont expect it to happen for another 50 yeas."
"post your engine serial numbers on here so that Dixon can verify you are legit. Sounds fishy to me. "
"Go buy a ficht or opti. you will be happier since you most likley don't even own a Yamaha.
Let's see new post bashing a product.
Seen guys like you all the time.
zero credibility brown boy. Now run along!"
Do all of you people go through life thinking everyone is trying to put something over on you ?
I believe you can tell someone to "go to hell" and have them look forward to the trip.
Such poor choice of words and open hostility, throw in a little name calling ,"brown boy", and you can really make a guy feel welcome. But I guess I should not expect better, after all Ed P called me Bay Boob!
browndog, do I understand you correctly that you have 50:1 pre-mix in your gas tank. Is this the instructions in the manual for breaking-in?
I just want to check on this point with you. I'm unfamiliar with auto-mixing systems so please bear with me.
I do know that most current Yammies have a normal 100:1 mix but a 25:1 pre-mix ratio for break in.
OK, now if your auto-mixing system is giving you a 100:1 mix that will approximate to 1 litre oil per 100 litres fuel. If you already have a 50:1 mix in your tank that would be 2 litres oil. Now that would be a total of 3 litres of oil.
A 25:1 pre-mix requires 4 litres of oil per 100 litres.
OK, OK I do know that it is not that simple and that oil-fuel mixing systems vary the ratio dramatically at different speeds, but that still means the ratio would be between 50:1 to 33:1. In any case, it would be leaner than a 25:1 ratio. Just checking whether your oil mixing procedure is as recommended.
