I have a 1965 version Johnson 18HP Seahorse that is not flow cooling water. I took the foot off, checked the impeller, replaced a broke o-ring on the shaft at the pump but still no flow after I re-assembled everything. So I removed the foot again and this time hooked a garden hose with fitting up to the water inlet tube. No water flows it just build up full pressure and shot back out when I removed it... I can locate and take off the thermostat cover and when I did I really didn't see anything in there, it just looked like an open chamber, I poured some water in and it did drain out but Im wondering if the thermostat is gone but even if gone I should still get flow through the bypass, correct?
Am I screwed? If the lines are blocked how would I go about confirming beyond what I already did and then how can it be cleared if it is blocked?
Thanks
