Re: gamefisher 15 hp
Asked and answered .. drilling a small hole in the thermostat housing laterally to accommodate a small piece of rigid plastic hose , then adding a vacuum hose fitting stepping down in diameter to up the pressure produces a fine stream of water that can be seen at a glance without having to crawl out the back of the boat to view.. I don't understand why chrysler of force, or whoever built the thing, would design something so important so crappy. I will try to post pictures for any one interested if I can figure out how.
