My rh starboard engine got water in the lower unit. My mechanic can't get to it for 3 weeks so I am considering a diy. I am mechanically inclined and have done considerable outboard work before, but no LU work. I will then pre-emptively replace the seals in the other engine as well.

When I look at the schematic, I see there are 2 seals below the waterpump, which I have replaced before on the other engine and 2 seals on the prop shaft. I am told there is another seal for the bearing carrier.

Do these seals come off easily without special tools?

How do I clean out the water in the gearcase? Flush it with something?

The seals are not hard to remove. You will have to remove the bearing carrier which requires a special tool fr the gland nut. Don't forget the seal on the shift shaft and the gaskets on the two screws used to change the gear lube.
