I'm hoping to buy a boat and I have looked at a couple of 28ft Coles. One is a mutiny which apparently had an overhauled engine refitted about seven years ago but there are no receipts???? It looks clean enough, starts easily and no smoke or complaints when on full throttle, but it doesn't seem to push along as hard as I was expecting? It is an 18hp volvo 2020 with saildrive and folding prop.

Would it go better with a fixed 3 blade prop and how can I confirm it is really a 18hp motor. I was also going to get a survey, any recommendations for someone on Lake Macquarie where the boat is currently moored.

Any help suggestions is appreciated, Thanks
