Water Pump Replacement '99 Merc 150

[randlemanboater]

Well boys, I got a late start because of rain and it rained on me for a few minutes while working, but it is done.

The key to this job was having a good helper.



That plus being able to phone friends while I was in the yard rasslin that sucker. *(Thanks Lord Skools) *Another mechanic friend helped me by pulling up diagrams on the computer while I was at the motor.

Once I found all the bolts holding on the gearcase (there are 7 in a Merc 150) it slid right off.



The good news was that the old waterpump looked fine.....that is also the bad news, I was hoping it was crap and I would solve my overheat problem. *There were plenty of signs that the motor had sucked up sand.







Putting the motor in forward gear was the trick, it all went back together real smooth.





And the results?

I don't know, it got time for church so I will have to test it out in the morning.
