Hey there everyone, like was suggested in the previous thread, I checked out my 188hp 302, Compression is good, points are gapped good, timing is set at about 6* btdc, and is going to about 30* at 3k rpms, carb opens all the way, and new plugs. The drive is set up for a 233hp 351, which would have a 1.5 ratio while I was told the 188 should be connected to an about 1.7 ratio drive. Adding a new gearset would be out of the price range, The boat currently has a 16x15 4 blade prop. Is there a prop I could use, such as a like 13x14, to get the speed and rpms up? Or could a 4 barrel carb with an adapter plate help bring the power up enough to get thru the low gearing? I ask becuase the 170hp 4 cylinder merc can be made to 190hp just by adding a 4 barrel. Your guy's professional input is very helpfull to me
