Re: Fuel:Oil Ratios

I’ts surprising to me how many outboards come through my shop with either no thermostat, or a faulty one that’s stuck open. This seems to be an often overlooked area in the cooling system. As Mumbles pointed out, an engine will never come up to operating temperature and ”burn off” if running to cold. I see it on Mercruiser engines too…nobody bothers to check!
