Interest in new 3 cylinder drag rules..motor alterations and mixing manufacture parts
The first interest I have is building a 49 cubic inch out of the 3 cylinder 40/50 hp Yamaha block.
How do you do it?
Second is matching up a 3 cylinder OMC powerhead with a 40/50/60/70 1:64 gear case.
What is the best way to do it?
Cut and weld mids- use an adaptor plate above the gear case- use a custom powerhead base plate on the Mercury mid?
Any pictures?
Thanks

Those Tiller guys know what is going on with drag rules (Mitch Hardee, Kent Foreman, Bill Kopod).

Thats the engine OMC should have made as yam just marched in with bigger triples and took tons of market
I quote you, Powerabout, and I'm not sure you said it. But if OMC would have continued to make two stokes and sold them worldwide, (Meaning outside the USA) they'd never have gone broke. I think you said that to me on the phone one day.
Seems, as I recall, my brother, asked Charlie Strang, why the 49 cubic incher was the way it was? And the answer wasn't what my expected. The answer was the NEW $100,000 mill wasn't large enough......It something that!!! My brother said, "Really?"
Too bad, you didn't "Take Over" OMC, Powerabout. You could have made OMC Great........I'm not sure I'll use the word "AGAIN".
I'd argue with you abut Yamaha. They took the WHOLE MARKET.
Very Cool Low Water Pick Ups
I've been thinking this way for years. But I wanted to cast the gearcase in stainless so we could make the skeg thin as hell and strong.
WOW! Very cool!
