I am looking at a 1999 fish n ski with a 150 Mercury outboard. The owner is running premix because the factory oil pump is shot. He says it is a plastic mechanical pump that wears out, is that true? seems like a terrible design. He bought a $500 electric oil pump that he leaves disconnected, I have a concern that this motor has seen a time when oil wasn't flowing and it may have seized. Are Mercury motors any good?????
Which leads me to the next question, what should the compression be on this motor? I want to do a compression test on it.
