Hey everyone-
Did Grady ever put twin Yammie F115's on the back of the 257? If so, where would I locate performance specs for that setup? I rode on a 257 once that I swear had 115's but I can't remember. Thanks.

I have a 257 w/ Yam 300 2-stroke. You wouldn't want twin 115s on it.

If I were buying again, I'd get the 350. If it were rated to 400 hp, I'd get twin 200s.

I agree that more power, the better. I had an old acquiantance whose boat I went out on a few times that was a 247 or 257 with twins...I know it was not twin 150's so I was thinking it was twin 115's. Either way, I would never get 115's....just curious as to the performance, that's all. Thanks for all the info. I'm curious if anyone has the 257 with the F350 on it...it looks like an animal! How is the reliability of the new F350 been overall? I'm not sure I'd be sold on a single if I knew I was taking it offshore regularly.

Twin 200's would be to heavy for the 257
