I'm looking to buy a boat that has twin Mercruiser inboards...V-drives actually. The owner states that they are 302s. The valve covers say 225hp. The boat is a 1974. Did they have a 302 that was rated at 225hp in the mid seventies, or are the motors actually 351s?
I'm admittedly not as familiar with Fords as I am GMs. These motor are definitely Fords though...distributor at the front.
I assume the 351 is a bigger block. Is there a quick and easy way to determine what these are? A measurement maybe?
