Dear Captain,

a friend of mine, we'll call him "Bill", has a 2001 Bravo III on a 5.7L engine in a trailer boat. Last year, while changing the drive lube, he left the drain plug and the vent plug out for 24 hours, yet the bottle in the engine compartment never drained. Filled up the drive and decided to leave it for 2014.

Fast forward to 2014, and he removed the bottle and blew air from the bottle side of the tube to the drive. a small amount of lube came out of the relief valve. Ran some grass trimmer line down the tub, so the tube seems clear. Pumped about 16 oz additional drive lube into the drive from the bottom, but the lube never made it up to the bottle.

Question 1: Where's the clog?
Question 2: How to unclog?
Question 3: Can he use the boat with the clog as long as he checks the lube in the drive every time he goes out?

Signed, Ernie

Just occasionally check for signs of oil behind the boat while stopped. A small oil leak will be readily apparent. Not really sure about the bottle, but Volvo Penta does fine without them.

My guess is it is in the check valve on the transom assembly. When you remove the drive on the righ side is a valve that prevents the gear lube from running out of the bottle when the drive is removed. Only thing I could think is that valve is clogged or stuck shut. It is actually called an anti dribble valve. You have to pull the drive to get to it.

Just keep adding oil to the bottom fill hole until oil shows in the reservoir. Do not run with low oil.

Takes up to 3 qts with reservoir

Yes, but if the dribble valve really is stuck then it would not allow the lube in the reservoir to flow down into the drive. The drive could run low on oil and you would never know it. When I change my gear lube, the oil drains out of the bottle.
