1999 Polaris Genesis. I need to know how to get the impeller out to replace the seals? In the repair manual it shows 4 nuts #26. But this has nuts on inside of hull but not outside.
I also am trying to verify that the drive shaft is not bent since this is the 2 time in 4 years that the seal has gone out.
Help!. Thank you.

Who replaced the first seals?
Here is the photo:

A Dealership that no longer works on them. Also yes where #21 is are there caps over the bolt heads? I can't see the bolts heads.

28 are the bolts. They are really long. They are the only thing holding the pump to the hull.
Just 2 quick questions. Are you having a water leak inside the hull?
Or are you getting water in the oil cone (number 37)?

Water inside the hull. So 28 attaches to the hull?

Yes the bolts are almost 2 foot long. You can see the full leangth of the bolt outside the pump housing. Number 31, the steering nozzle, may need to be turned or removed to see them.
seals number 16(2 of) are to keep the oil chamber sealed. The pump nose cone.
Water in the hull is a sign of bad propshaft seals.
This is the thru-hull coupler with hose, 14 through 19. Its inside the engine compartment directly behind the engine, on the driveshaft. With the Polaris in the water, this is what you will see leaking into the hull. If the seals are bad.
If you don't see water dripping from here, then water is coming in at another location.

so we still have to pull the impeller out to get these seals out correct?


by: Bill   on: Thursday, April 1 2010 at 12:25:19 CDT

Yes remove those long 4 bolts to get the pump out first. The driveshaft will be left behind.
Are you near the polaris so we can do this step by step?

We have already remove everythinig to the stator housing and that is where we are stuck.
All the water around here is frozen over. However before we took it out last fall we looked in and none of the hoses were leaking and the grease point had fallen out that was just behind the motor on the drive shaft.
Also since this has happened 2 times over 3 years I figured it was the same thing, but I wanted also to check the drive shaft to ensure it is not bent. The first year that this happened my wife ran over a ski rope so this is what has lead me to believe that possibly the shaft is damaged.
Please let me know your thoughts. Thank you
Mike.

You said the grease point fell out? If you talking about the grease fitting(number 14). That would cause bearing failure then seal failure, after all the grease washed out with water. That could be the source of the leak.
