If it's clean, chances are good it was the gaskets on these screws that allowed the water in.<br /><br />Regardless, chances are very good,your l/u is still in relatively good shape....You caught it before it grenaded, (and providing there are no chunks of metal larger than a grain of sand), not really hard to take care of with the manual on hand.<br />It will pay for itself on this one job alone.<br /><br />First, remove the prop, and inspect the seam for any lube.<br />This would indicate a bad prop seal.<br />Better yet, get (or make) a fitting that you can thread-into iether the drain or fill holes.<br />Attach it to a tire pump,and pressurise it to 10psi (no more). If it leaks-down, you have a bad seal or seals, and will now have to submerge the lower unit with the tire pump attached..Pump it up,look for bubbles.<br />If you have bubbles from behind the prop, the prop seal must be replaced..(this can be done mounted).<br />If the bubbles come out of the water intake, the crankshaft/water pump seals need to be replaced. (might as well replace the impeller whilst you're in there).<br />Good luck,and lettuce know how it goes, or if we can help ya long-distance any further. <br />--------------------------------------------------------------------------------<br />Posts: 2745 | From: Lehigh Acres, FL, USA | Registered: Mar 2001 | IP: Logged
