Bought a 24ftr with a 454 330 drive. I know nothing about gm motors or the drive. It says 330. The boat has 522hrs and the previous owner had boat more than 22 years. Boat looks good enough for people to think its newer than it is.

So, put about 5hrs on boat when she started to over heat. Had boat up to 60mph, little scary with those trim tabs. Please correct me if im wrong.Heard it is the impeller but pulled thermostat out to check. It works. Bought new 1 anyways. Water inlet on bottom of boat, looks like goes to a water pump on block? Is this a big job? Cant find any info tag by transmission to identify motor. with the year an model of boat, is there anywhere I can get repair manual and any info on Boat? Any help would be great. Wife not happy I buy boat an cant run it.

is this the one in wisconsin that was on craigslist

Yes Pump out on mechanics bench.

Slap an impeller in it an go. Take the hose off the water circulating pump and back flush the coolers. Water will come out of the soft hose that connects to the pump. Make sure you get the soft hose and the reinforced hose back in the same spot.

Can not find engine serial number. any suggestions on replacing distubutor? still has points.

looked like a nice boat for the money
