Water in lower unit?

[steplift20]

Hey guys, I'm going to attempt to replace the seals that are under the base water impeller . I think you have to pry it off and the seals are under there ,is there any advice you can give me? Like do I replace the O Rings and should I coat them with a light coat of grease when putting it back or no grease ? It's a 1988 -150 Mercury outboard and advice would be greatly
Appriciated and if anyone is in my area and wants to help that would be great too

get the new lower water pump housing, it comes with the seals installed. The water pump kit with upper housing comes with all the gaskets and o-rings you need. Just takes two screwdrivers to pry the lower housing out. Put grease on the seals, I use Mercury perfect seal on teh o-rings, nothing needed on the gaskets
