Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

Am in the process of purchasing a 2003 Hydrasport 26' CC. Boat weighs about 8000lbs with twin engines. I have two possibilities for power: Yamaha 200 HPDI or 200 4 Strokes. Would love any feedback on pro's and cons, personal experience, etc. I believe the HPDI will offer better performance including more economical fuel burn but think the 4 strokes may be quiet and offer more longevity and better resale (as well as no oil burn). Thanks in advance for thoughts.

Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

WOW, you are going to get a lot of different responses here, but here is my shot. I have an 02 200 HPDI. It was my choice. I just could not quite justify the extra $ for the 4 stroke. If I was sure I would have the boat longer than 5 years, I would have gone with the 4 stroke. Two strokes will be around for a long time yet. But that was for me, everyone will have a different take on what they did or want. I do love my HPDI, awesome performance, sips fuel, and oil. In fact, I would be hard pressed to say I could get that much better mileage with the 4 stroke. Oil use? depends on how much you use your boat. That can also help you determine if a 4 stroke will be better off for you. I can't say enough good things about my own motor. Again, others will have different thoughts.

Does any of that help you? Get what you want or can afford, and don't have one bit of regret with either purchase!

Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

The only thing I can say for sure from my own experience is that a 200 Four stroke idles quiter that my HPDI. I like the HPDI that I have had for three seasons but when I got it I didn't have the choice of a four stroke.

Yahaha's Outboard web site has a link for "performance bulletins" were they test dozens of motors on different boats. It may be worth a look.

I think you are going to want the extra "ASS" that the HPDI's will have with that big Hydrasport. I have twin 200 HPDI's and could not be happier. 244 hours and no problems. Sips the gas and the oil.

I have heard the differences in noise are most prominent at idle between the 2 and 4 stroke. If thats what your basing the decision on, I think the performance benefits of the 2 stroke outweigh the noise factor.

If your looking at 4 strokes, why not 225's? That Hydra is rated for 450. The extra 50 HP may make a difference.


Nice boat and good luck,

Scott

Based on experience, I just ordered a second pair of HPDI's. If they run as good as the first I will be extremely happy. Never had an issue with the first pair. Fuel economy was 2.4 mpg @ 40 mph. As previously mentioned they hardly use any oil.

The boat manufacturer says that the 4's are definitely quiet, but lack mid-range performance. Which is a feature I enjoy.

I would definitely stay away from the "Saltwater Series". It is a gas and oil pig compare to the HPDI. At least twice the oil consumumption rate.

My personal preference would be twin F225's. As Scott D mentioned, that boat is rated for 450 hp. Most people that now have 4-strokes will tell you that they have no intentions of going back to 2-strokes. However, if weight on the transom is an issue (as related to performance, transom strength, and scuppers), the 200 hpdi's might be better. I'm currently looking at some larger boats with twins (including the 26' HS), and though I prefer 4-strokes, I might have to opt for the 200 hpdi's for the reasons I previously mentioned. I would honestly not be fearful of either motor. I would strongly suggest trying to ride on the 26' HS with each setup before making your decision. Again, if the weight of the 4-strokes is not a factor, you will not be disappointed with them as long as they're propped right. Good luck.

I'm not a saltwater angler but on one of our Finger Lakes in NY,a sheriff stopped me to ask questions,he had a appr. 20 foot rig with a Yamaha 200 HPDI, told me he racked up 750 hrs. on it with no problems but spark plugs every 100 hours,I was impressed.

This is why it's so tough to figure what you want.....Every stat and performance issue about the 4 stroke I have ever read or experienced states the four's lack the low end grunt of the 2 strokes(however minimal) and have better mid-range/top end power than the 2 strokes.
Not doubting what the manufacturer told you Bluewater, but it's totally opposite of everything else I have seen.

Gat the 4 strokes!

Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

Guys - Love the feedback...any more would be welcome. I am running the 26 with the 4 strokes tomorrow (Monday) and on Tuesday will run the 26 with the HPDI's. I'll report back the results for those intertested.

By the way I am looking at rigs already set up (demos) therefore the 225 4 strokes are not an option. Also, the price for each boat is identical and both boats have LOW hrs (les than 50).

Class,

Its incredible that you can run both of the exact boats with the setup you deciding between. That shold make the decision a no brainer for you. Pick the setup you like better. If both rigs can tell you fuel burn numbers, your all set.

One thing I would suggest is that the dealer provide you (or you be there...beter) with a printout of how the engines have been run and how many hours the computer says they have.

Just don't trust the dealers word....your spending a ton of money and he should be more than willing to prove to you the motors history in an undisputable format.

Good luck,
Scott

Four strokes have a higher retail price, thus making the four stoke a better buy, if it fits your performance numbers. If you are not waterskiing, is holeshot that important?

Class Act- Be sure to note WOT rpm's. If either set of motors are not propped to run at or near their top rpm's, you might get the wrong impression on performance. You have a very unique opportunity to try both setups. Enjoy the ride and let us know what you think afterwards.

Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

I went through that same decision last fall and bought the 200 HPDI. Very happy with it. Yes, the 4-stroke is just a little quieter at idle, but still low noise. Very little smoke, meaning low oil comsumption, and really kicks my 24 foot walk up on a plane!
Not sure if you can be disappointed with either decision.

Default HELP! Yamaha 200 HP HPDI vs 200HP 4 stroke

No one has mentioned the maintenance. The 4-stroke has alot more moving parts and requires a more expensive 100hr check. I would inquire about that aspect. Who cares about topend, how often do you get to do that? Sound? They are both quiet, naked ear can't tell that much difference running at 3500 or 4000. Fuel economy is about the same. Weight should not be an issue on that hull. I have 575hrs on 2002 200hp HPDI's and could not be happier. To me, the four strokes didn't make sense but alot of people love them. I am interested in hearing the comparison.

The 4-stroke has alot more moving parts and requires a more expensive 100hr check.As I sit here looking at the maintenance chart in my 4-stroke owner's manual, I don't understand what you're referring to. What exactly is the extra maintenance at 100 hours over the hpdi?

My manual lists fuel filter (water seperator), engine oil, gear oil, and greasing points. As stated in the manual, all of this can be done yourself.

Items for the dealer every 100 hours: Inspection of fuel filter (disposable type), oil leakage, and oil seal. Note the word inspection. Replacement only if necessary.

Is this truly more than what's in your hpdi manual? If so, how does this supposedly higher expense compare with your 2-stroke oil expense?

I'm not bashing hpdi's at all. In fact, I'm considering the 200's on a larger boat with twins (only because the 4-strokes are not an option due to weight). But concerning maintenance costs, I don't get it. But I don't have a hpdi manual to compare with...
