water in lower unit

2008 250 Pro XS I went ahead and dropped the lower unit and brought it home with me. Is it a very difficult job to change the seals since Im already gonna change the water pump since I have it off. Just to let you know I have changed lower unit 3 times since new this would be #4 but there was enough water to to make me pull the unit.
Any advice appreciated http://www.bassboatcentral.com/smileys/USA1.gif

You really need to have it pressure tested to see which seals actually let go.. More then likely it is the shift shaft seal due to over filling the lower unit with lube..

+1 on having it pressure tested!

Shift shaft or Driveshaft seals are relatively simple to replace.

The propshaft seals, on the other hand, require several special tools (and I do NOT recommend someone attempt replacement of these seals without the correct tools and training). http://www.bassboatcentral.com/smileys/wink.gif

Pressure test should be performed at various pressures with NO LUBE in the gearcase. A spray bottle of soapy water is helpful in determining the location of the leak.... start at 2psi, 6 psi, 10psi, 15psi (do not exceed 15 psi). Rotate each shaft while listening for escaping air (and spraying soapy water on each seal). http://www.bassboatcentral.com/smileys/wink.gif

Note: and INNER propshaft seal leak will likely not show up until 15 psi. http://www.bassboatcentral.com/smileys/wink.gif

Thanks guys gonna pressure test it tonight http://www.bassboatcentral.com/smileys/bows.gif

yep 15 psi and here comes the bubbles. I wonder if this will be covered under warranty

IF you're under the FACTORY warranty period- Yes (provided the seal leak is a defect in materials or workmanship).

If you're under a Product Protection period- probably not (seals and gaskets aren't covered under the Product Protection Plan).
