I purchased a 97 Moomba Boomerang in the middle of the summer for what I thought was a good price.
Ran fine on the hose in the guys driveway, but would barely start when I got it home. I had a friend, who is a former marine mechanic rebuild the carb. When he took it off there was a gasket missing, and the high speed screw was completely closed. We also found ewater in the gas. I syphoned the water/gas out of the tank, and added dry gas, but it still doesn't idle, and sometimes puts out black smoke. It also sounds like it is backfiring through the carb when running close to WOT. I just had it winterized, but am trying to figure out where to start next spring in getting it running right. My regular marina specializes in outboards, and I've heard some stories that doesn't make me want to take this inboard to them, since their shop rate(like most marinas) is so high.
Thanks
