Chrysler V-8, 240 HP,LM318 inboard. I rebuilt the pocket pump(raw water pump) with a new rubber impeller.Changed all belts. Cleaned out all old rubber debris from old impeller.Changed thermostat. Test ran the boat-still over heating. Would anyone have an idea were I go from here? I'm at my wits end.
PS: One exhaust header runs hotter than the other-less water flow to that side. Don't understand why? Thanks in advance.
