This seems somewhat complicated.
I bought the referenced engine and had our local outboard repair person attend the initial startup.
It had not run in about a year. The carbs obviously needed some work but that is not my most urgent concern.
It started and ran fairly well, given the conditions stated.
I asked the the local expert what he thought and he said it sounds like the main rod bearings are getting ready to go. The question to him was--how do you figure that?
He said the engine was making a wooooooring sound maybe like a large fan or something like that. My ears don't seem to work in that frequency and the sound was not noticeable by me. It sounded like a typical running outboard motor with a miss here and there.
I can return the motor and get the money back. The dilemma is the motor is mounted on the party barge along with the control box, etc.
Question: Can failing main bearings be determined by listening to the motor run--the answer is, of course it can but this would depend on the degree of deterioration. If it is getting ready to come apart, there would obviously be noticeable noise.
I have confidence in out local guy but I really don't know what the next step should be. We checked the compression and got 120 on all three.
Would somebody offer some insite---please?
