Hey fellas just walk in you through what I'm doing and what's going on
Shifting gears on my 99 25 hp 2 smoke yamaha was getting funky
went to change gear lube - check up
no lube - just a few ounces of terrifying saltwater- no metal sshavings
Filled her closed her up . Shot out the inlet for a quick limit on tIles.
Cameback . Few ounces of saltwaterand milky lube .
So it's aggressive.
Pulled propgreased ssplines cchecked prop shaft seal.
Found mystery rubber grommet behind prop used a coat hanger to pull out. Will load picture soon.
Plans- order seal kit. Re lubeand pressure test .
Anything else I should be doing?

Did you check driveshaft and shift shaft seals?
Sucks, but at this point i wont reseal a lower unit anymore unless i do all the seals at once

that's good advice !

just replacing one seal is asking for trouble !
reseal the entire lower unit - replace water pump
pressure/vacuum test !
