Borg Warner trans leak

[bud37]

Source of the post Hmmm... I think I like where your going with this. it isn't really "dripping" its more spraying as the shaft spins. and as a matter of fact, at this point its still so minor that its just not a HUGE mess. but my crazy clean self is down there cleaning it up every time.

I'm gonna have to think about how to rig this without running the risk of it catching the shaft and causing me much more troubles.

Can I ask....did you recently have the drive fluid changed ?...just curious.....get yourself a shallow drip pan to fit under the trans and line with oil pad, then run one pad up the stringer on one side and the other, stay away from the coupling...


Km this is the drive in question I believe...same as mine, almost impossible to work on in the boat.

Ahhh.. V-drives! Maybe there's some unused mounting holes that you could screw a bracket into?

Yep... that's my drive! as there is no appreciable "drips" on the unit itself, only the spray on the bay floor, I'm assuming that lower seal around the shaft is where it's coming from.

Embarrassingly enough, I'm afraid I have NOT recently changed the fluid. Was actually thinking I need to, just have not. Maybe my fluid is old and thin and if I change it the thicker new stuff won't leak????? haha.. sorry, grasping at any straw that means I don't have to pull the engine!

So I was thinking of taping down the oil mat to the floor and stringer, my only thought is... its a 350 Mariner, and water just sorta finds its way in there with any rain that may come. Not a lot, but enough to make a mess of those mats. of course the drip tray idea is cool, as it may help that problem, I may have to sit yoga style in my engine bay for a while and really visualize all these great ideas. My girl is old (2001) but myself and the original owner have kept the bays pretty darn spotless since new. So all these ideas really have me thinking on how I can keep it that way!

There may actually be some truth to that....I think if you do some searching around the web you will find some info on the shaft seals in those trans, the upgrade, and the fluids they came from the factory with. Shared sump trans /gears much like a tractor etc.....interesting.

You can buy plastic pans of different shapes and sizes that can be cut to fit quite nicely.Make sure that stainless drain box and hose for the deck drains are clean and clear, I clean ours frequently ( spiders ).....

Boy that would simply make my day! I definitely going to do that!! as a matter of fact, that may be tomorrow's project!

FYI......... some hydraulic fluids come with seal conditioners as part of the additive package already there.....just check with the manufacturer of whatever fluid you are using.

This is an old post but if that output shaft seal is leaking it will only get worse. Unfortunately I am pulling my engine and trans next week to have the trans rebuilt. Same problem but it needs to be pulled to do it right

[km1125]

Well, as long as this old thread is up top again... here's another idea.

You could get a little pan that fits the area, and line it with some oil absorbent pads. Then use a few velcro pads to stick it to the hull to keep it in place. Then you can still pull the pan out to clean it and then stick it back down on those velcro pads when done.

Wonder if anyone else is having these issues with V-drives. My Velvet drive 72C is model 10-005-005. I am sick to my stomach to find out how much one of these cost new. Over $9K! I am told misalignment or prop strike are primary culprits for this shaft seal leak. I called Hale Marine which seemed very knowledgeable but told me these cast iron v-drives are nothing but trouble. He explained the output shaft and intermediate shaft are over $3K. I hate to spend over $5K rebuilding a transmission. I am curios what others who have a 72C vdrive have experienced? This boat is only a few months old to me and I love the Carver Mariner 350, but I dont want to be dealing with trans issues that cost more then new engines. Please share your experience with V-drives. I wonder what the gentleman on this post ended up doing with his leak?
