anyone ever put a yammi 350 on a 90 25'trophypro instead of a two motor app. was wonderin how it performed. i really don't put heavy loads in her anymore. just use it to drift around for flatties and some striper fishin in the fall.
I intended to put an f350 on my 2005 258. Grady said "no", the transom wasn't made to take that much torque in one spot. This even though my boat is rated for twin engines up to 350 hp. Your answer will likely be the same, if you ask.
