Re: Thermostats????
Ok, Here is a report. Since removing the thermostats and figuring out the shift interruptor switch was bad, I may have taken it out 5 to 8 times in which one of those times I cracked a piston, and another burnt up the rings. It was sept. when I throttled down and heard something knocking, I idled back to shore and tried to figure it out. After a little bit more running it started sounding better. I beleive now after seeing inside I cracked a small piece of the piston, not sure why???? When this happened I had not run but a couple minutes, and water temps were in the 80's. Anyway, that it went back to running ok, and I got back home. Now it sat till January. Fired it up in the yard found a fuel line leak and it started was sounding good. I thought maybe that had been the problem. took it to the river, ran it about 15 min at high rpms, and it sounded pretty good, except for a slight variance at wot. So, the next time out I make a short run, fish a few min and start her back up to move and she is grumbling, I idle back and do a compression check to find 0 on #2 cylinder. Now after a bad experience with a crooked boat mechanic, I am trying to get her fixed without losing any more money.
I have sleeved the #2 cylinder, and have close to 90 psi on all 6. I tested the thermostats that I took out and they both worked, I put them back in and they made a difference on how hard it peed. It now puts a hole in the ground like it used to.
I doubt that this will solve my main issue of no power. But I think, despite my grandpa's vast wisdom, the thermostats are a good thing.
We had trouble with the timing, now we think we have that fixed, It barely planes out, then only runs about 4000 rpms. Trying to figure out if its fuel or something in the ingnition system.
I dont' know what happened in that cylinder, but I doubt it was taking the therms out. It was the hottest time of the year when it cracked the piston.
