Flow from water pump indicator

I just repowered my boat with a new E-tec 150 hp.outboard   Took it out for the first time and it ran fine.  The only questionable thing I saw was the flow of water coming from the water pump indicator.  At idle it pulses out of the port instead of a smooth stream of water.   The pulsing is in time with the rhythm of the engine at idle.   I had a 150 e-tec and a 90 hp e-tec on previous boats and always had a strong straight stream of water coming out at idle.    I let the motor run at idle for a long period and it never changed in flow or ran hot.     is this normal??

Re: Flow from water pump indicator

Normally the water outflow is a steady low-pressure stream just like your earlier model E-TECs. Is it a steady flow when the motor is running faster?

Hard to tell at WOT.   Water was a little squirrelly yesterday and i didnt feel to comfortable hanging around the transom.  My previous E-Tec's had a smooth stream of water as you stated before.   It pulses along with the way the engine is idling.

Re: Flow from water pump indicator

Have someone drve the boat while you watch the flow when you run the boat, in forward, at about 1000 rpm.

 

About the only thing I can think of is possibly a broken water pump impeller vane but that would be a super rare occurance. As long as the motor runs OK and does not overheat have a dealer take a peek if you can.

 

You are seeing this while the boat is in the water, right? Not on a flushing hose?

Re: Flow from water pump indicator

Yes, I noticed this with the boat in the water.   I have not run the motor with the flush kit.    I'll try to do another test this weekend.   I may could take a short video with my phone and post it it that would help.   The closest dealer to me is over 2 hours away so I was just doing a little research before hauling it back to them.
