mercury water pump impeller

check the hole if u did not already mudd dobers r very busy this time of the year might have blocked hole just putting it out there i would also take it to a empty ramp or get somes muffs for it i have had bad luck with the tubs before not picking up water i think it has something to do with the exhusts and the water moving around

Thx for the replies I think i'll try putting it into the lake and see if it still does it just might be moving water in tub around to much but think if it's ok will change it anyway Thx guys

My 150 merc will not spit out any water with muffs on in the driveway. I know of another guy who has a 225 and it will not spit any water out as well. I am guessing it has something to do with the water pressure.

My b-in-law had the same trouble years ago out of his 50hp merc. A mechanic rerouted the water line somehow. I need to look at it again. But as far as it not peeing, it might not be the impeller. Insects will crawl in and make a home out of it. But if you are going to take a look at the impeller, just put a new one in. couple of dollars vs. what could happen and most likely will happen.

A reminder to everyone. No matter what size of motor, do not use a garbage can to supply water. What happens is that the exhaust and peeing water creates air bubbles in the can. When the motor picks up the water, it also picks up the air bubbles. It will still pee, but won't have the water needed to keep it cool. Always use ears.
