To all. Before I left for work tonight. I noticed the shift lever housing bolts were loose, and after taking the housing off, I noticed water under the gasket. Again, I rebuilt the lower unit this winter with all new seals, some bearings, shims, impeller, etc. However, I didn't have all the correct bolts to bolt everything down the first time I put the lower unit back together. When I got home from work, I installed the correct bolts to bolt down the shift lever housing, with some gasket sealer too, and will install the lower unit sunday. With that, and installing new lower unit seals on the gearcase screws. I'm hoping that will take care of the "milky" oil in the lower unit. I will run the motor in a tank, and let you all know the outcome. Thanks again Guys. Dan

In my experience, the black oil oozing stuff is pretty much a "normal", or at least common part of 2 stroke exhaust. My guess is that the oil in the lower unit oil is a different issue - like someone suggested, the 0 rings on the fill and vent screws possibly.<br /><br />Regardless, don't go with less oil than the 50:1 mix.

Did you replace the seals on the lower unit screws when you changed the oil? Try that and see if it's still getting water in it. Otherwise, rub some of the leaking oil between your fingers and give it a sniff and see if it smells like oil/fuel. If so, it's unburned exhaust oil/fuel mix nad nothing major..

Replacing the Shift Cable Bellow requires removal of the drive and replacement of the shift cable.

Contrary to common belief, the Exhaust Bellows will not allow water to leak into the boat.

Does your automatic bilge pump constantly cut on?
You might have a leaking transom assembly.

The rubber bellows should be replaced about every five years or sooner if you suspect a leak.

Water can leak in other areas as well.
It can leak in at the top of the gimbal ring where the steering shaft passes into the boat. There is a seal which holds the water out but the shaft is hardened steel which can rust, pit and ruin the seal. This requires removal of the gimbal ring. Buy a Service Manual before attempting this repair. more

The "transom assembly" is actually the Gimbal Housing Assembly.
The Gimbal Housing assembly has rubber components that can rot and/or rip and leak.
The two rubber components most likely to cause a water leak are the Ujoint Bellows and the Shift Cable Bellows.

If your boat is stored on a trailer, you will eventually need to start your MerCruiser engine out of the water. Whether you are getting it ready for a summer of boating, or just fixing a problem, it can be started out of the water with the proper tools. You must have a set of outdrive muffs. These can be purchased at any boating store. Failure to supply water to your engine will cause the impeller to burn out and the engine to overheat.

[zmauricepittmanj]

Attach the outdrive muffs to a garden hose.

[packetloss]

Place the muffs over the vents in the outdrive. There are two vents on each side. Make sure the muffs are completely covering the vents.
