[QUOTE="Pappy, post: 443666, member: 3278"] [size=5]If you have been trying to run it on muffs then there is a good chance you have damaged the impeller already. Only takes a few seconds to start damage. If you want to run in a "bucket" make sure the water level is up above the level of the water pump. One of the reasons no gaskets were needed is because the pump was designed to be submerged to prime. Once up on plane your water pick up will force water to the inlet side of the pump. There should be a seal beneath the lower plate on the water pump. That seal is a driveshaft seal. That the one you are asking about? [/size] [/QUOTE]
