Q1: [Implied] How is the water pump serviced on a 2001 Mercury 115-HP FOURSTROKE engine?
BACKSTORY
I have 2001 Mercury 115-HP FOURSTROKE engine on a 2001 16/DAUNTLESS. After removing the lower unit, I found a rubberlike covered metal sleeve in the middle of the driveshaft. The water pump cover cannot be removed until the sleeve is removed. The sleeve is 6- inches above the water pump cover, about 1.25-inches wide.
The rubberlike material looks partially burned.
