1985 Evinrude 150 XP, model E150STLCOH,
580 hours
Fresh and some saltwater use
Primary use - water skiing and tubing
Garage kept
The voltage will vary between 12.3 and 14.8. Will occasionally go up to over 15 - reading from gauge and fathometer. The tach is very irratic, often not working at all. As the day goes on, the engine becomes harder and harder to crank, unless you let it sit for over 30 min. But the stopping to pick up a skier, then recranking becomes very difficult.
Engine signals a solid tone OFTEN - but can not make it do it. I do not think it is overheating due to checking water pump outgoing water temperature and engine with an infared heat sensor gun does not indicate a problem. I am not sure how to check for a blocked fuel line. Once cranked, performance does not seem to be affected.
My concern is with the life expectancy of the regulator - due to prior problems. We bought the boat on 1/31/1987. It went to the shop in 2/10/1987 for voltage regulator replacement - after 30 minutes of run time. On July 17, 1988 the voltage regulator shorted out internally and caught fire. It was again replaced in 2005.
Any assistance or suggestions would be greatly appreciated. My husband and I bought this boat new and it was his "baby". He passed away in 2010 and I am trying to keep it going to continue that part of our lives. My oldest son will be home in 1 1/2 weeks and wants to go skiing!
