I am rebuilding a 1981 30 foot Thunderbird, Formula which originally had twin 330 mercs. I am a newcomer to boats and am having a hard time trying to figure out which engines to power with and what size. Just wondering if maybe someone else out there has already gone through this. Also looking for any other info on rebuilding this boat.
Rocketman, I would go with Big Block chevy's with bravo 1 drives. Post this in the Hot Boat Hot Spots forum and you can get more response. THere is a guy called Old Rigger who knows tons about building/rebuilding. Good Luck!!!!
