I hope someone out there can give me some help on a broken ysb8. The engine has given me no trouble since I bought the boat 4 years ago. The other day though coming into the channel it did not seem to be coming up to full RPM and slowly over about ten to fifteen minutes to RPMs droped unitll it quit. I tried to restart it and got some white smoke which someone told me it was steam. I have been told to check the impeller , the fuel filter was cloged , the water intake is cloged . I pulled the water pump and looked at the impeller and it looked ok since we were on our way to Molokai I did not have the time to really to look into it. Now that I am back I need some guidence on were to really start on getting this thing fixed. The engine is 33 years old should I just rebuild it and how hard is it toget rebuild kits? Any hlep I can get will be greatly appreciated. Thanks Brian
