Water in the Lower End ahhhh!

[chip0004]

Noticed gearcase lube at the exhaust hub (prop) so I drained the lube and found a good amount of water. Went to the IBoats on-line store and I have 2choices. Either a Small or Regular gearcase.

How do I tell which one I have?

I assumed that I should replace the Impeller and associated gaskets/grommets, while it is apart. Any other parts you would suggest I should purchase?

Also, before I get too involved, is this something a fairly mechanically inclined guy, who has the Seloc manual in hand can undertake?

Thanks bunches

Probably the prop shaft seals leaking.A pressure test would be my first step.
Yes,change the impeller while its apart.
The Seloc may get you by but if you are planning on doing your own work invest in the real manual.Its much more specific and detailed.
Post your engine model year and serial,you will get better help..

To pressure/vacuum test a lower unit:

a) drain the gear oil
b) use an appropriate adapter with a gauge tee'd in to apply pressure or vacuum. No more than 15 psig for pressure. You can use a bicycle pump or any other compressed air source for pressure. For vacuum, you need a vacuum pump.
c) LU should retain some pressure or vacuum for 45 minutes minimum.
d) If pressure doesn't hold, submerge LU in water to find leak source [possibilities: drive shaft seal, prop shaft seal(s) (usually two), shift shaft seal and the fill/drain screw washers.]
e) replace offending seal(s) as required.
