Hi so i'm not sure if this is the right place to post, but it is a mercruiser drive so I'm sticking with it haha. My aunt has a 2000 seadoo challenger 1800 with the 210Hp M2 jet drive, and recently the oil pump decided to quit. According to the mechanic the oil pump seized but their was still oil in the line, and he also said that one of the cylinders had loss compression. He didn't elaborate much more on that, my question is what kind of damage could have been caused internally by that pump failing? The motor in its current state does turn over, but it won't start, so the engine isn't seized. The mechanic wanted to just pull and replace the whole motor, but is that the best option? I'm just trying to get a little more information so i can proceed and make an informed decision. Please if you need more information don't hesitate to ask.
