Post subject:  GDSD Need New Seals?

Do I need to replace seals in my surface drive? I have attached a photo of the grease that came out of the drive shaft near the prop. I replaced the pressure lubricator and followed the instructions some of you helped me on. I shot grease in the proper zerk and the new pressure lubricator filled 1/3 of the way full. As the lubricator was filling up, I noticed grease coming out the stainless steel collet next to the prop. I stopped pumping the grease gun right then. The unit is an '07 so I bet the seals have never been replaced. Any feedback is appreciated. This is my first mud motor so the thought of replacing seals is somewhat intimidating for fear of f*cking something up. Any advice you have for that is also appreciated.

X2 on what Robn1020 posted...


My understanding is that seals might be due for replacement under
normal use at 250 hours - or - 3 years....

Also use of the correct Go Devil grease is advised - that sure
isn't GD grease coming out back there - LOL

At the time you change that real seal inspect the shaft for
signs of a groove forming which could lead to shaft failure and
replace the shaft is the groove is more than the thickness
of a thumbnail.... Believe they run about 100 bucks for both...

Ok. Good info. I wasn't aware go devil had their own grease. The manual says to get #1 or #2 marine grade waterproof grease. That blue sh*t is the marine grade at least. When I order seals, I will order the go devil variety. This particular motor was not run in salt water. Regardless, when I replace seals, I will inspect the shaft for wear. How much do the seals cost and how many are there to replace? Thanks

You need your frame's Serial Number when you call...

But call Go Devil up - they will set you up with what you need...

No SN - no parts...

I am disappointed to find this problem. I was planning on taking this rig to the coast this weekend. Is this a terrible idea now that I know the seals aren't good? Or can I just keep it full of grease so the salt water cannot come into the drive shaft area? I will be stripping it down to replace the seals regardless in the next week or so. So, I would think I will be able to prevent any real issues at that point anyway. I paid a good chunk of cash for this rig so I do not want to do anything that could permanently damage it, yet I paid a good chunk of cash for this rig so I want to get out and use it as much as possible! Again, your help is appreciated thus far.

Go for it - run it...

The damage has already been done - you most likely
need a shaft and seals.... Order 'em up and run the Mofo
like ya' stole it till they get to you....

You push an entire tube of grease thru that GTR - what every 15 hours...

Sounds more like a bushing than a seal - LOL...

My GDSD has 200 hours and 2 years of hunting - toasted 4 props and have
only used half a tube of lube and ain't even changed my spark plugs....

Dude in the same time you are on the third powerhead ! ! !

I ran the red Lucas grease that I bought at an autoparts store. It seemed to work good for me. The dealer I bought my GDSD from ran the red Honda grease. I'd buy a couple of tubes and pump out all ofthe old grease. After that, you may have to add from time to time.
