Re: Big Block in a 23' Tsunami ?
Alan,
Joe would certainly know better, but I don't think the Ford 351 block is used by any marine engine company any longer. I believe Indmar and Pleasurecraft used to use them, but not anymore. I'm not an I/O guy, I've only had outboards, but what I do know about them, I'd certainly go with Joe's suggestion. You're getting a bulletproof engine block, good power and torque, a very reliable drive unit, and a huge dealer network.

Re: Big Block in a 23' Tsunami ?
Amen, Scott - I hope so. I have had many boats and all had o/b's. This is my first step into the " love 'em or hate 'em " world of i/o's.
It's a little unnerving; lower units/electrolysis, engine/overheating, manifolds, risers etc. It's nuts how many opinions there are out there on which is the best drive or which motor is best. For a laymen like me it's very confusing. I do rely on pro's like Joe though. I don't want any emotional opinions - just straight-up facts like; " we have put this motor in many boats like yours and they perform great and are durable " ! That is what I hear mostly about the Mercruiser Horizon 5.7 300 HP. As for the best drives, that seems to be an elusive point. I guess that's the price I will pay for essentially building my own boat... The work is hard enough, but all the variables of how to do a specific part of the project or what drive to use can certainly 'drive' you nuts !

Re: Big Block in a 23' Tsunami ?
About the only part you can use is the oil filter, and some gaskets. Everything else is different. The Mercathode system is wired to your batterys so you do not need to be pluged in. It does not draw that much power. The bravo II is a good drive you will have no problems with. I do not believe there is no Fords in the sterndrive lines. I believe there is only one still being offered in the inboard line put out by PCM.
