Motor for Pontoon?

You would not be able to put a 90 HP motor on the transom of the 1984 floteboat. You would have to beef it up by adding a new transom pan (about $400.00). You may want to reconsider fixing up the last one (looks like a Crest brand).. 

Me, I'd bicker on price for the motor because it'll cost you close to 300 to rebuild the cylinders on the tilt/trim (labor & parts). Yeah, they ask a lot for a motor and I don't know the normal trend up there, but down here, I can find deals for 800 all day long (even if they ask 1500, wave 800 and 80% of the time they'll take it).  Seats with wood bases - generally bad as they'll cause floor to rot quicker once it starts but overall guess that's ok (look at crossmembers for rust, that'll tell the story above it). Trailer price seems within reason too IF its in very good shape and I didn't see any pictures of it.

 

I also don't like the fencing on that boat, to me a slant front just wastes space behind it and in front of it (but that's just me ) but it is what it is. I'd take the railing off the other boat, put it on this boat (swap fences) and sell the other boat. I agree with you that its just a wiring issue for non-working guages and stereo (should be easy fix, look to ground wire connections FIRST). I'd rewire just for GP's if you can afford it (plus I find it FUN) Yeah I know, I'm sick that way
