Re: Ground Problem?

Well, nothing to lose by pulling the heads at this point…Unfortunately, if the lower seal is at fault, water has usually been pumped up to the top bearing and has rained down on everything in between…Lower seal problems usually don’t seize the pistons to the walls, so I would suspect something else if the cylinder walls are badly rusted/seized. These closed deck engines have a tendency to corrode the tops of the cylinder sleeves, the design tends to trap salt water in that area unfortunately. I was hoping OMC/BRP would have gone to the oring sealing method like on the 60 degree engines, but don’t think that ever happened….
