Weak telltale with muffs

[kenroughty]

Have an '85 Merc 60hp. ever since I've had it, there has been very little to no water comming out the telltale while using muffs. I've repaced the water pump assy, but still very little stream. When the motor is in the water the telltale shoots out past the side of the boat. It doesn't have to warm-up, it comes out within seconds. <br /><br />I don't leave it running long with muffs, just enough to get some fresh water in it. <br /><br />Any thoughts? <br /><br />Keith

Re: Weak telltale with muffs

sounds like you need more water pressure at the muffs. Muffs are not a good way to determine efficiency of the water pump.
