View Full Version : My drive shaft is getting hot

06-09-2011, 09:57 AM
I was boating in the Columbia river over the weekend. When I removed my boat from the water I noticed I had steam coming off my drive shaft. As the water was 53 degrees (brr) I was wondering what I was seeing. I reached down and felt my drive shaft and it was very warm.

A fellow wakeboarder suggested it is a problem with my drive shaft bearing. Does anyone know if I can service it, ie lubricate it, or do I just have to change it? If I have to change it, is this something I can do myself or do I need my dealer to repair it? Is this expensive?

Thanks. 2007 PWT XStar

It's probably more likely that your shaft packing is too tight. The shaft bearing is always submerged and always lubricated by the water, so it's pretty hard to build heat at the shaft bearing.

Have you checked the shaft packing drip rate lately? Do you get any water in your bilge after running all day?

Do you have the dripless shaft seal? If so, what you are seeing is the warm water from the engine discharging through the seal and shaft log down the shaft.

I have never looked at my seal. I am getting water in the bilge. I did not check if it is warm.

If you have a dripless seal, Eric @ OJ probably nailed it. If not, check the drip rate next you've got your boat in the water and go from there.

The suggestions on here sound like good starts... But, I might suggest reading your manual so you know what needs to be done, checked and when.

Sorry, no real help here.

my 07 star is dripless, you should have the same.
Better to have a hot shaft than a bent one :)

Thanks for the advice. I will ask my mechanic.

Also, here is a good picture of our boat on the Columbia river. I unfortunately lost the pirate flag in the picture.
