I bought a boat that has been sitting for almost a year. I replaced the fuel filter,plugs and greased up everything. I also changed out my lower unit oil. It had grey streaks in it. Could this be from sitting or is it water. There was not allot. Also there is allot of play in my engine I can move it left to right with one finger. I found some hyd fluid leaking out of the cylinder. I plan on buying a rebuild kit. Will this fix my problem? Also anything else I should look for from sitting so long?
