Sealed rear end???

[leatherlungs]

Can anyone tell me if the rear end diff and axles are sealed? For example, when I back my boat in to launch, or recover, do I need to worry about water getting into my diff and ruining my diff oil? Thanks

You should be ok. Thats what pinion seals and axle seals are for. If they are leaking then you might be at risk of getting water inside.

Thanks, appreciate the response

What about the vent though.

One thing you might be concerned about is backing hot rotors into the water.

If you been on the brakes hard and just partially submerse the rotor in the water it can warp the crap out of them.

Thats a good point. Never really thought of that.

No need to worry about your diff, you're good.

I would make sure you extend the vent tube high enough so it is not submerged or you can get water in the diff.

There isnt a vent tube in the rear diff, only the front.
