My boat 1986 model 3870
The generator has run close to the upper end of the green zone since I have owned it....nine years
Now it is slowly creeping into overheat, so I shut it down.
Anti freeze changed end of last season.....just checked the impeller and it is fine.
So, does that only leave the heat exchanger and thermostat?
Should I remove the heat exchanger and take it to a radiator shop?
What other issues whould cause overheating?
Advice welcomed...
