I have a 1994 Crownline deckboat. I had it docked for about 2 months on a freshwater lake. After about a month and a half of being on the lake we had some pretty bad storms in which twice my cover had failed. The first time my engine was hydrolocked post the storm. The engine had not been started for approx a week before that. I pulled the plugs and replaced them cranked the water out inspected the cylinders and cranked back over. Then about 2 weeks later we had another massive storm in which the cover was taken off by high winds again. The engine was hydrolocked after that storm also. Pulled the plugs and everything was fine. So my question to you is Where do I need to start diagnosis to figure out where the boat is taking the water from while its docked? I never have any issues while its running only when its been docked during a big rain storm. The engine is a 4.3L V6 Mercruiser. I just dont know where to begin or what to look for with a marine exhaust.
Thanks!
Thanks!
