Don't run it any more with the water pump out or you will do damage. Hot engines can result in loss of compression, scored cylinder walls, holed pistons, and other problems all of which are far more expensive to fix than installing a new water pump. You might want to do a compression check anyway to see if compression is affected.

Aaron,<br /> Dont put $ in it if the compr is lower than 110 lb. and within 10% of each cyl.<br /> These motors also plug up at the telltale and if it doesnt flow after the new one is installed ,put compressed air @30 psi right into the outlet while running.The motor stopping indicates no cooling so do drop the lower unit and put in the new one.Mark the little shift shaft with a pencil or feltpen BEFORE you drive out the little pin(lower one leaving the connector to the upper as it wont fit thru the grommet!),then the lower assy. slides down to reveal the water pump.DO NOT remove the plastic block below the water pump housing as it has the drive seal which you dont want to touch!Goodluck!<br /> TM
