I put a 1998 25HP Johnson 2 stroke on mine that I found at a pawn shop for $850 total with taxes. Starts very reliably and I have had to do little to it except change the pull cord and a tune up. That was 2 years ago!!! Look around or with gas at $3.00 a gallon let your fingers do the walking call a bunch of WPB pawn shops.
Good luck with the boat. Maybe we can rondezvous some time- St. Lucie or Jupiter inlet.
