Drive lube reservoir leaking?
 

7.4 and b1....I've been getting an awful oil burning smell so I traced the source, I seem to be leaking drive lube from the reservoir cap and its dripping down on to the exhaust manifold then onto the engine block finally pooling in the bilge area. When the engine is cold the drive lube is at or just below the full line on the reservoir. After the boat has been driven for a little bit the oil level rises the spills from the reservoir cap. When its hot the drive lube looks very frothy like there is a bunch of air mixed in. Although it's been leaking I have not yet had to add any lube to it (stays at the full line). I' am new to this boat but I do know this cant be normal just looking for some input as to why this is happening and what I can do to fix it!!
Thanks.

Might try a new cap sounds like it's not venting

We only fill the reservoir about 50/60 full to allow for expansion. Try just leaving the drive oil level where it is and see what if this fixes the issue.

don't want to scare you but sometimes when the drive oil rises substantially it's because the oil is overheating because something is going bad in the drive.

Hopefully the bottle is just overfilled.

Now you got me worried... lol! If its doing this now whats going to happen when I put the procharger to it (crunch)... The lube in the reservoir does not smell burnt if thats any help and its not leaking out of the vent on top of the cap, but out of the threds of the actual reservoir. Does the diaphram on the inside of the cap have a pressure rating or does it just slowly let air out? Livorsi sells these fancy little caps would one of those do me any good? Would it even fit?
Guys thanks for all the help!

could have water in fluid maybe?

All good leads...pull an drive drain plug and see what kind of wear shows up on the magnets. Very light fuzz is ok...chunks are not. If you aren't sure, post a picture.

Thanks BenPerfected, I am guessing that the magnet is attached to the innerside of the drain plug? Located behind the prop correct?

Correct

The upper plug has a mag also, do you have a drive shower on, its not a bad investment if not. Simerek makes one that bolts on no drilling anything

Yes, I do have the bolt on drive shower. If I have time tomorrow I will pull the plugs and see what comes out. Keeping my fingers crossed.

Ok guy's I drained the gear lube from my outdrive and found no sign of any water.... the gear lube looked just as blue as the new stuff. The magnet on the lower drain plug had the smallest amount of fuzz on it (no chunks). After doing some more research I came across another forum with the similar problem. That person was told to check inside the cap for an O ring and to make sure it was in there. I decided to look under my cap only to find a missing O ring hmmmm. I went down to the local parts store and ordered myself a new cap and O ring just so I cross that off the list. I refilled the outdrive with new fluid and put some fluid in the reservoir and now I am counting the days till the weekend so I can try it out.
Still not sure whats causing the gear lube to become frothy?

It's probably just airated. For the most part the bravo res. is designed to let air in but not out. If you were missing the o-ring you're probably good to go! Fingers crossed.

Mine has allways foamed up,but its vented:confused:

Got a napkin so I can wipe the drule off my chin? HaHa

Cause we have BMax drives and it's supposed to. It's an expansion chamber, unlike the Bravo which is a rez.. :)
