Hi Everyone,
I recently bought my first boat, a used 14' Grumman fisherman deep-V, plus trailer and 1988 Mercury 2-cycle 9.9 hp outboard.
Today I decided to "winterize" the motor as I don't plan on taking the boat out until spring.
1) I lubed all the lubrication fittings
2) I changed the lower unit oil. It looked fine when I drained it. I removed both screws and filled it from the bottom until it flowed out the top overflow.
(It seemed to take more oil to fill it than what drained out.)
3) I filled the can with fresh gas with 2-cycle oil (50:1) plus Stabil with ethanol treatment.
4) I started the motor and let it warm up. The lower unit was submerged in an 18 gal tupperware tub of water. (I noticed that the water seemed to become a
bit oily)
5) After the motor warmed up, I sprayed some CRC Engine Stor into the carburator for about 5 seconds. The motor struggled then stalled (normal).
I turned the water off and was preparing to remove the spark plugs to squirt some engine stor in the holes, but I noticed what looked like "runny milk chocolate" running down the motor shaft from the "tell tale hole"
At this point I stopped.
Does anyone have any ideas on what's going on?
I've never owned an outboard before, but this doesn't seem right.
Did I overfill the lower unit oil? (I was very careful not to!)
Do I have a leaky seal?
I'd really appreciate some recommendations on how to proceed.
Thanks!
