Product Description

used Mercury 75hp two stroke oil injected long shaft. This has trim and tilt and is set up as a remote. This will include controls and prop. This has had the carbs cleaned and new oil lines installed. We also installed a new water pump impeller and pressure and vacuum tested the lower unit. We performed a leak down test and all three cylinders were at about 13-15% which is a little higher but they were even and the cylinders looked good with a bore scope. A leak down test measures the percentage of air leaking past the piston and rings, this is more accurate than a compression test. On the leak down tester there is a gauge that reads 0-100%, 0% being the best and 100% the worst, typically most motors have some percentage of leak, but your looking for as close to 0% as possible and typically anything over 20% that cylinder will not run right or if there is a big variance in the cylinders. Overall this is a very clean freshwater motor that I believe should be a good running motor for a long time yet. This starts and runs with no rattles and shifts fine
