hi, i have an old 64? mercury 5.5hp outboard. I think thats what it is. But i took it out early this summer and after warming up a little bit after being away since last year it ran great.
it was really fast and worked fine.
but later that day when id start it up it seemed to just go a litle slower that it did earlier. and even just a little slower yet the next time i would start it.
i took the boat out a few more times in the summer and each time i ran it, it progressively got slower.
it would rev just fine in neutral and sound good. but as soon as i put it under load it would rev really low, the last time i took it off we could barely move and it was kind of difficult to keep it running out of neutral.
Anyway....... someone told me to put 1/4-1/2 Cup of transmission oil into the gas and run it for 5 minutes or so.
I guess its an old trick that the old timers used to do with small engines to clean them out. Anybody know of this? Is this the right ammount?? Thanks
