I have a 1985 20' Glastron CVX Intimidator with 350 ci V8 and it is rated at 260 HP. It is I/O with speed prop and mercury alpha outdrive. I saw an ad for the exact same boat, same engine, everything but the owner said it has 325 HP. What would I need to do to mine to add the HP?
Optional Information: Make (of engine): Chevy 350 short block Year: 1985 Horsepower: 260
We need the serial number to determine what you have, some guys like to post the total HP and not the prop HPHe could have the 4 barrel carb also and could have faked the HP
Experience: Over a 15 years of working on all the brands of outboards.
