257 Advance - Engine Repower

[jasgator5220]

I'm considering repowering my 2004 257. I'd love to jump up from twin 150s to twin 200s like they put on the newer models, but my year is rated to 350. Not sure the extra 50hp is worth it and may elect to just keep running my current set of engines.

Has anyone repowered an older vintage 257 to twin 200s? Thoughts on whether I'd need to strengthen the transom? Also curious what this may do from an insurance perspective?

Just trying to steal a little wisdom from this group. Thanks in advance for your thoughts.

Sounds nice, but where will you find new motors?

In addition to possible insurance issues with overpowering, there is no easy way to know if the transom is beefy enough for the extra horse power.

Thanks, the transom delta is only 50hp. Regardless, I probably need to look at this another way . . . is 50hp worth it to potentially have insurance issues . . . its not. I'm moving on to better props and other means to get speed up a bit.

For 50hp its not worth it from an insurance point of view. God forbid anything heinous happens up to loss of life. The insurance companies will forensically check everything . You do not want to be on the wrong side of compliant.

For future consideration I think there is an in-line 4 version of the 175.

Suzuki and Yamaha make 175s
