Hello all...I bought a used Stratos boat last weekend and checked the compression today (it was a friend of a friend that assured me he would stand behind it if something were wrong and the battery was dead so I took his word on the condition). Anyways, it was 75lbs across the board with the exception of one reading 85. This boat has sat for 2 yrs so when I did the compression check it was the first time it has been cranked over since. Would this be an accurate reading and it is time for a rebuild or could the reading be misleading from it being sitting for so long and the oil draining from around the piston/cylinder walls?
What compression is typical for these outboards? I would think you would want to be atleast over 100 on a used engine. The biggest thing is it has been sitting for 2 yrs though. Any input would be greatly appreciated!
