First of all, I'm not going to get into name calling. I've OWNED my boat for 23 years. It had a Johnson 235, three years later, I put a 200 on, in 2001 I put a 225 yamaha 2stroke I would cruise at 3700-4000 a lot. My f225 now cruises at 4700- 5000 rpms with the prop I have. What don't you understand that 1) the four stroke I have is geared lower than my previous motor 2) the 15" pitch prop turns more rpms. Saying that you use 20 -25 gallons a day means nothing. Saying that since your 200 hpdi works great, does not mean squat in comparing it to the inline 4 four stroke.
I don't know how the new 200 will work and from what I'm hearing from you, you don't know either. If the original poster ever comes back and tells us how it works, after he buys it on your recommendation, that would be relevant.

That was my point back on post #3. As mentioned above the 3.3 225 Yamahas were really wimpy engines (Moose is right on his numbers), however the Yamaha marketing machine sold a bunch of them. They are doing the same with the I-4 200. Again I do not have personal experience, I'm going by other folks opinions. The Maverick forum had this same discussion a couple of years ago on this engine and that's where I got most of my info. What you don't want to do is compare the Yami I-4 200 to the eTec 200HO, it would be embarrassing to the Yamaha with the difference in actual power/torque. Crazy difference.

I had a F150 on my 22' Pathfinder I just sold so don't think I'm anti Yamaha.

getting heavy ....I have a late 70's 23 with a new inline 4 200 hp yami , in my neighborhood, I will check into it as soon as possible.both the 150 and 200's are torqued four stroke beasts,imho!!! besides who's gonna fix a glorified ficht.Isay if they run good they are great,if you have a problem,good luck

Yup. Agreed.

Running a single on a twin engine bracket...,does one have to run a 30" shaft motor ..my experience on another boat says yes,but don't know about Seacrafts.

Depends on how high the bracket is installed, but I put on a single 30" on twin 25" engine bracket on my Contender and I had to get a 4" jackplate and raise the motor way up to get the AntiCavitation plate out of the water.

My buddy had identical setup and he went with a 25" and it was too low and and he couldn't trim it without cavitating.

Dave you mean the engine was to high @ 25".. Yes my experience was with a 25' trophy wa. It had twin/150s .. He went with a single 225 and had to extend the foot cause the motor would cavitate and slip when trimming ,choppy conditions and turning... The boat did sit higher than before with the extra weight not being there. Like a couple inches higher...

[dave s]

Yes, the 25" was sitting too high; I was thinking of my 30".
I like how the 30" powerhead sits higher up out of the water; I got back wash on the 25"s when I slowed down too fast.

[capttodd]

Yes Martin, you have to run a 30" shaft on a twin Hermco bracket.
