Does anyone have any information about an after market automotive pulley that can replace the Mercruiser raw water pump pulley 862351T?
 
All I find is oem for around $70, but considering a power steering remover/installer is used ,have you looked at power steering pulleys
 
I have looked at some videos on the removal of a pressed on pulley. The tool can be purchased at Harbor Freight. It may be just easier to bring the front of the pump to am automotive shop and pay the cost for the removal and install. The pulley is original, and I don't think that removing it( correctly.) will cause it any harm. My Merc dealer says he has his customers purchase a new one because of the problems in the removal of the old one. Could be that they have different responsibility then me in the install of the water pump. The only other company that sells the pulley is Dorman, but I cant seem to fine the size ( O.D) that Mercruiser has in the Dorman serpentine pulleys.

I took mine to an automotive machine shop and they charged $30.00 to press the pulley off and reinstall it back on the new pump. They used a torch to heat it up, stuck it in a press and it slid right off. No pulley wobble and the belt runs true. They know what their doing and that's worth every penny.
