Seabob,I have a '97 21.5 Dual Console that I just repowered with a '04 250 HPDI. My next upgrade will be to put a new aluminum trailer under the boat. Do you know how much this boat weighs? I think the Yamaha and the 200 Ocean Pro are pretty close to the same weight.Also, do you know if this boat has any wood or foam in it?Thanks - you are a great resource!MikeR

Mike,You may have a corrosion issue there. 12V, but what kind of amps? Just a guess...
