Was on the waters of Chincoteague VA over weekend when I hear the siren going after about 30 mins of part throttle cruising. Dropped RPMs back and siren stopped. Eventually, it came on again. "Weep hole" output is not a steady stream.... more of a sputter & a dribble. Sure looks like a new water pump is in my future. Motor is 1991 Merc 135 that I've owned for about 8 weeks. Unknown if/when water pump was ever replaced by prev owner. Any tips or "gotchas" on the pump install? I have Clymer shop manual for motor and tools to do job. Should I do pump install now and hope to use boat a few more weeks or quit using boat and winterize now? How many more weeks of boating do we have in Chesapeake Bay area? Of course, one person's "too cold for boating" weather is not the same as another's. What would a Merc outboard shop charge to install pump? Thanks.

THe water pump/ impeller is a simple replacment. With a good manual you can do it in an hour.
Be sure to purchase the pump kit and not just the impeller. The kit includes all the gaskets you need to replace. Check the pump housing for cracks and only replace if damaged. This rairly occurs.
Be aware that the alarm is also triggered for low oil or oil pump problems.
There is a sticker inside the couling describing the difference between water and oil alarms. I believe water is a continous alarm, oil is a beeping alarm.
