"Hello everyone. Newby here.
I have an issue with my outboard and I am getting kinda thin on ideas (and hair now)
A little background. I bought this boat last fall from a friend. Just before I bought it it was tuned and carbs were rebuilt by a boat repair facility.
I take the boat out and it runs perfect 80% of the time. At random it would stumble at idle and refuse to run. When this happens I have to crank it with the fast idle lifted, push it down and throw it in gear.
Then at random times it wouldnt run top end. I would push it into forward and it would bog but run and slowly get itself to speed. Once at speed it ran perfectly.
A guy told me to check the inlet needles. If it had black tips it was junk and to find factory inlet needles that are all silver. I pull the needles and they were black. I buy factory inlet needles and put the carbs back together. At that time I find one of the floats were slightly out of range. I adjust that and get the carbs back on.
Last night I hook the muffs up, prime the bulb and crank it up. It ran high for about 20 seconds and calmed down to base idle and then it started to die out again. I gave it a bit of fast idle to let the engine warm up a bit and ease it back down a minute later and it refuses to idle.
Funny thing is I will take it out on the lake in a day or two and it will run perfectly, or may not.
The bulb stays tight. New gas tank, new fuel hose.
I might be forgetting some things but the fuel pump was rebuilt too.
This is a 1989 Mercury 45 (classic fifty)
Any ideas would be greatly appreciated."
