Just got boat,my 7hp honda pushes boat better.<br />local shop said exaust plugged/drive shaft froze in pwr head,will have to cut in half to repair. For 900.00. Any ideas,other than the saw,would be great. A picture of center section would be really great. If I can get a close cost on parts also.. Also the boat is a 16'starcraft/open bow set up to fish. With motor what should I expect as far as speed/should boat get up on plain? I was told this was to small. THANKYOU.
