Leaking gear lube reservoir

[dlogvine]

I found some gear lube under the engine. Looks like the reservoir plastic container is ok, no visible leaks or cracks and most likely the leaking occured through the lower nut or cap that has a hose coming out and two wires (connecting the low lube level sensor?) sealed into it. This nut does not look to tighten or losen up when it is being turned and I was not able to remove it. So I bought similar container ( used one) and installed it replacing the old one. However the replacement container has the same problem. Seems to me like I'm doing something incorrectly. Thank you for your help.

I took my reservoir apart last year to clean and inspect for the source of a leak. Like yours there was no visible damage to any part of the assembly. Putting it back together was a bit tricky. IIRC that nut you mention was difficult to tighten. The hose port had to be pointed in the correct direction once tightened. I had to remove and retighten the nut a few times before I got it right. Also, I was unable to snug that nut as much as I wanted too. If I tightened it to much the hose port was out of position. After several attempts I realized that just snugging that nut was enough to crush the gasket/seal and stop any leaks. Also,
be careful to get the float installed correctly. It has a metal band on it to trigger the level alarm. I installed mine upside down and when I started the boat the oil level sensor in the float set the low oil level alarm off. It's tricky getting that float off and on but can be done. If I were you I'd put it all back together and test it for leaks. There is minimal pressure there so it doesn't take much to get it sealed properly. I hope this helps.

I was not able to remove the nut, since it seemed to be spinning without getting off. So I tied it up and made sure the hose port was in the right position. The leak either completely disappeared or it is insignificant. I will have to test this boat on the lake to see if it will start leaking when the lube gets warm. I was thinking about using a marine sealant around the nut to make sure the leak is gone completely, but Im not sure if the gear lube will eat through the sealant or not. Will see.

prolly best to not use a sealant. I'm betting you'll be fine

I finally took apart the whole assembly. Using extra long needle nose pliers made the job much easier. The lock washer on the top of the float rod was a little tricky but again with help of the extra long needle nose pliers was much easier task. I also changed the rubber washer and tightened the nut, while holding the inside nut with the same pliers.

Mine was leaking as well through the center where the two wires come down through...plugged it with some 2 part waterweld and has held up great since.
