1. starter will work once then just a click is heard. Wait 10 to 15 min. and it crank engine again. If I want to change starter unit where can I find one?<br /><br />2. When engine is running it will not come up to speed and plane boat. Have checked timing, fule pump pressure and volume. Carb. has been cleaned . Does any one know what size prop I should be using. Since we got this boat used from a privite person I have no idea of prob dia. and pitch. The one on the boat has no markings. The boat is a 1972 cris craft bow rider 16 feet long.
