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).
