I have a 6HP Chrysler Model# 64H9E. That's the right model, I noticed previous posts about this model resulted in skeptical answers due to the model missing from certain publications, but this is it. I believe the conclusion was that it's a 1977 or 1979 model.
Skip this part if not interested.
I posted about my problems with this motor last year, and let it sit outside over the winter without having found and fixed the problem.
This weekend, I opened it up again, cleaned the carb, made sure I had sparks in the plugs, and changed the fuel. Still didn't start. Invited the neighbor over to tinker with the starter, and we found that the timing wasn't set correctly. We're not pro's so, we just used the "stick-the-screwdriver-into-the-spark-plug-hole-and-turn-the-flywheel-until-the-cylinder-is-almost-all-the-way-out" method. So when the cylinder was almost at its peak, we adjusted the points to be an eye-ball approximation distance of .02" like the etching on the thing said.
Having done that, the motor still didn't budge, and the conclusion was that I probably have poor compression. So I went out and dropped 30$ on a compression guage. Got back, pulled the starter just for fun once, and the motor coughed. Pulled it more and it started for a few seconds. Since that point, it would start and run for a few more seconds every time. So I cleaned the carb again, and it started running and starting pretty consistently.
I tried the compression guage just for fun to see what it would show, but I guess I don't know how to use it right. I screwed it in, and yanked on the starter cable once. The guage showed about 30 psi. The more I pulled the cable after that, the higher the psi's went - up to 100 I think. At which point is the actual compression measured? After the first pull? I would think you have to measure the compression that the cylinder creates by moving from one side to another just once.. But pulling on the starter probably does that more than once. Since it seems like the compression guage is set to just add up the compression with every pull, it's not very helpful.
Here's the meat of the current problem now:
After getting the motor to start and run a little outside, I mounted it on my boat. Started it and ran for a while. I twisted the handle to max RPMs but it would not rev up even half way and was coughing and running inconsistently. At low rpms, it ran very smoothly without interruptions. After a few minutes I noticed smoke/vapor coming out of the powerhead and concluded that the water cooling system isn't working. The motor was very hot, and I noticed that there was pressurized air spewing out of some opening on the back side right into the water, where I would think water would have to come out.
So my question, is my assumption about the broken cooling system correct? And where could I find an impeller for my motor? I've looked around online and there don't seem to be parts for my motor.
Any help would be greatly appreciated.
