Re: 1973 - 65 HP Evinrude throttle/choke linkage
Yep. It's amazing how well a motor can run without the high speed jets completely gummed up from sitting with fuel in them for 7 years. I am now paranoid about the water pump not pumping enough water. I replaced the impeller when I started this motor recovery, but I'm thinking that it's not getting the water all the way up the water tube. I was able to verify that the tube was clear by removing the t-stat cover and holding a water hose to the tube. I got water sprayed all over me from above when it shot out from the relief valves. The basis of my paranoia is that I don't see water coming from the exhaust relief ports just above the water line while the engine is at operating temperature. Every so often, while under way I see water spurting from it, so I'm thinking I may have a stuck t-stat or at the very least a lazy one. I have a kit on order. Also, the seal in the pump housing is most likely the original, so I ordered the pump repair kit so I could replace all the seals and the grommet (should have done that originally). I may be losing pressure around the drive shaft, because when it's on the muffs, I can see water leaking out of the exhaust housing right around the pump. Parts should be in mid-week, so I'll update then.
