It is very normal to want a on the water test run if you are serious about buying the boat. I know of many people who have bought boats without one. Some of them are happy with the boat, alot of them are dissapointed with it not performing up to there expectations.

A compression test is a simple procedure to do. You can usually find someone who will loan one to you. If not, Harbor Freight Tools sell them for $20. You might be able to rent one. Anyway, when you find out what motor you are looking at, call a outboard mechanic and find out what the compression is supposed to be for that motor. Then remove all the spark plugs, screw the compression test kit into each spark plug hole and crank the motor over a few times to get the highest reading. Compare the readings to what the compression is supposed to be. If they are way to low or the there is a big difference between one cylinder and another, then stay away from that motor.
