Bondo, thanks for the welcome and the advice, I bet the people who know you call you Richard Cranium not Bondo:-( I'll post pics tomorrow. In the mean time if someone else has a constructive piece of advice to my original question I would be very grateful.
Ayuh,.... Friends call me Bondo, 'n when you figure out exactly what you have,...
You'll see I'm Right....
#1,... The Iron Duke, has never been used in a Boat,... It's a Car only motor....
#2,... The Bravo II has Never been put behind a 4 cylinder motor, Especially an Iron Duke....
#3,... A Bravo II drive is so Big, 'n Heavy, it'd sink a 14' boat....
Now,... As DCMS says,... Post some pictures, 'n We'll see if We can figure out what you've Really got....
And,.... Just for the record,...
NO,... There's No jet-drive available for any Mercruiser outdrive....
