I'm schedualed to take it in on mon to Dave at Champion Marine over in the west SF Valley. I had them do an expensive tune-up, service, water pump impeller replacement, lower unit re-seal etc back in late feb to get it ready for the season. So, I guess they, at least, should have an idea what it has had done recently. When I took off the cover and looked at it myself, I saw signs of a past overheat, which indicates to me that some of the electrical system might not be in the best shape. In that last servicing I had them check out the motor and check the compression etc, so that much should be ok. Plus about 50% of the time it runs strong. One problem I have also noted is, despite the new impeller, it has zero water pressure at idle and I have to give it some gas to keep the pressure up. When cruising it runs about 12lbs.
P.S. Thanks to all. Where does your water pressure guage hook up to the motor? That is not enough water pressure for me. My 235 will cruise at 12 psi and runs over 20 psi at 80mph.
