water impeller question

#1 Post by ROLAND » Sun Jun 30, 2013 11:56 pm

Quick question for you " outboard mechanics" out there. During this past off season, when I had my boat serviced I had a new water impeller put in.... so today when I had the boat out for the first time I periodically looked back to make sure there was a good stream coming out of the "pee hole".... and there was..... but my question is, when I shut the motor off, I noticed that there was still a stream of water coming from the pee hole for just a bit.... now it may have done it the whole time I've owned the boat and I've just never noticed it ( which wouldn't be surprising since I wouldn't be looking for that with the motor off ). But i did notice it today... shut the motor off and the water continued to stream out of the hole for a short time. Is this normal? I was kinda thinking that maybe since this is a new water impeller that there may be better "pressure" which causes the water to continue, but that's me just taking a wild guess. Never did hear any alarms or anything and the motor ran just fine....

I have only owned 4 other motors and all of them have done that for a second or two.

The water pumps are self priming, and it takes a few seconds to get the water up to the engine. On the other hand, modern outboards are self draining.

Remember that in the winter, you never have to drain the engines. The water has to go somewhere via gravity.
