leaking impeller

[brodiecolton]

Just pulled the boat out for summer, I noticed the it was leaking from behind the impeller. also when I turned the boat of I noticed it would still leak or more like a weap from behind the impeller. ( on the backside of the housing where the shaft goes in. Is this just a seal that needs to be replaced am I ok to run the boat for a day or two until I can get the part to replace it. The motor is a 2001 PCM 5.7 HO the impeller sits on a bracket in front of the pump. also I just hooked up my shower is this an ok place for the cold water line.

RE: leaking impeller

As long its a small drip and there is plenty of water to cycle through the system its fine - as long as your engine temps stay within reason your fine. Might just need a new o ring, but while your there you might as well drop a new impeller in. Neglected impellers cause more down time on the lake than anything else...

Is there an O ring behind the impeller? I know there is the large o ring in the front cover, replace the impeller last year. sure I will have to replace it in order to get behing to fix what ever is leaking. I have never been able to get an impeller out without tearing it apart.

Just the one o ring, and a paper gasket on the back side - see the other live thread on this topic. Interesting that you never get the impeller out without damaging it, as I've never had that problem, I just spin it out so to speak after winterizing the boat.

I don't ever remember seeing a paper gasket on the back side. is there a packing bearing or something behind that would cause the dripping and weeping when the motor is off? Just trying to figure out what I need to order.

double check your clamps and fittings as maybe one of them isn't tight or in the right spot. I noticed when I de-winterized my boat this Spring I hadn't fastened the hose & clamp on the water hose going to the transmission cooler correctly (when I winterized it) and hence it was leaking.

The paper gasket goes on the other side of the thin metal plate that is sandwiched between the two sides of the RWP housing. The o ring contacts the other side of the plate.
