My boat has a B3, I haven't used the boat in about a month and it's on a lift above the water. I just went out to look at it this evening and noticed the drive oil was waaaay low at the reservoir...Well below operating level.

If there were oil in the bilge I wouldn't be able to see it anyway, b/c the lift has a slight tilt to the back.

Can the drive leak while not even in use? Is this a pull the drive type situation?

I'd pull the drain plug briefly to see what comes out. If it's drive lube as it should be then I'd do a pressure/vacuum test on the drive. If it holds then top off the reservoir and monitor it often.

In order to perform a successful Pressure Leak-Down test, the gear oil must be drained.
It must be drained because the seal's lip is hydraulically assisted while under pressure.
Remove the oil..... and the pressure test will better reveal a breach!

The Vacuum Leak-Down test does not require the gear oil to be drained.

Went out to check it today and I may have misjudged it a bit I guess since it was dark. It was a bit low, but not much. I think its possible that it may still be burping from the drive oil change. I ran it about an hour to an hour and a half today and it didn't seem to budge. Its back on its lift now. I'll check in a few days and see if it drops. The bilge is NOT clean. So, that concerns me.

The hose on the bottom of the reservoir can leak where they connect. Just run your hand under the reservoir by the hose and you'll soon see if that's the culprit.

This appears to be the issue. I didn't get down to see what was under there. Is it as simple as tightening a nut, or do I need to replace the reservoir tank?
