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...

I'd like to add a third battery to my 2004 247 Advance. This third battery would serve as the "house" battery and collect a charge from the engine alternators in the same manner as my current two batteries. I like the idea of not running the radio, etc. off of batteries my engines are dependent...

So how does the head work on this thing? I know, dumb question. I have a 2004 257 w/ head inc. macerator. I can't seem to find the Y-valve. Any help is greatly appreciated. Thanks in advance !

New to the forum and appreciate any insight on the following. Two weeks ago I acquired a 2004 257 Advance with twin 150s. This is my first time operating with twins (I previously had a Dusky 203 w/ a single 150 for the past seven years). On a few instances, as I've throttled up, the boat wants...
