    I had a few emergency jobs that pulled me away from the project, but as soon as warmer weather approaches I'll jump back in. I'm also working on a 84 cu. in. 3 cyl 90 hp Merc for my 14' 6" Andrews hydro. The 90 hp Merc only has 85 pounds of cranking comp. for use worldwide with low octane gas. A friend said that by raising the comp to about 140 and a few other easy mods like porting, it will put out 130-140 hp. I am going to machine the blind cyl head away and use screw in 'o' ring, replacement cyl heads. I cc'ed the stock motor and it had 48 cc, I will be shooting for about 36 cc, which should just make it 93 octane pump gas safe. I'll post pics of the project soon.
