Water in lower unit.

[gramwood]

I recently bought a 1990, 90 hp Force, Spectrum combo. I was told that the motor had not been used since last August but the previous owner said he thought the motor needed a new impeller. Upon draining the lower unit, about a quarter to a half cup of waater came with the lower unit fluid. Will this cause future problems after the impeller change? The lower unit had not been drained for about three years.
Thanks for any input.

Water in the lower unit is a problem. Could be something as serious as a bad "O" ring seal or something as simple as a bad gasket on the fill or vent plug.

Try filling it up and running it and checking everytime you run it. The best way to check is to let the engine sit for a couple of days and then break the drain plug loose WITHOUT loosening the fill or vent plugs. If there is any water in the lower, it will come out before the oil. Keep the plug close to the hole so you can get it back in quickly.

If there is water or milky oil, you have a leak and need to fix it.

Like they said either a fill or drain flug O ring or even (not sure what its call) the bushing like seal that is in front of the prop, youll need a manual to replace that because on some older models they use a spanner wrench to remove the prop shaft spanner nut etc. Just hope you dont have a pin size hole or crack in the foot!
