Some History:
Compression between 80-85 on all 6
Replaced VRO with replacement kit
Use seafoam on about every fill up
I have had problems with this motor for the past 4 years and have used this site multiple times. I think I'm close, but still not quite there. I continue to think it's a fuel issue, but now I'm not sure (maybe electrical??). I have learned a lot about my motor, but am definitely not a mechanic.
When I took it out for the first time this year, it just didn't act right--stalled a few times even after warmed up, but started up right away each time(Although, I never tried to open it up, just idled around). So, I decided to take it in to the local marina. The mechanic didn't act too enthused about taking on my old motor, but said that he would take a look at it. Anyway to make a long story short, he said that the compression was too low and it was on its way out. He told me that he did run it, and it powered up fine. He suggested to go down to a 21 pitch prop to plane out quicker, but I didn't think that was the problem. So, I took it out the day I got it back and it ran great....I was very happy (only short lived).
This past week, I was on the lake everyday, and ran into some problems. When I first would start it and let it warm up, it would power up great and was able to open it up to WOT. Then, when I had to go through channels at idle speed and would try to open it up, it wouldn't go. Sometimes it would act like it would go, and then bog down. It would run great at about 10-15 mph, but just not power up. Sometimes after I had it off for awhile, it would power back up. Basically it would work about 1/4 of the time.
I just don't get why it will work sometimes, but not others!!!
Please help, and sorry for the long post.
