lovetofish Posted May 18, 2007 Report Share Posted May 18, 2007 Just went out to try to tune my boat because it wasn't running quiet right. And noticed i had no water flow out the back of the engine. So i took off the two covers for the water inlets and saw little pieces of rubber (which i assume is the water pump fins). Does anyone know where the water pump is or how i get to it. I am mechanically inclined so i'm pretty sure i can do it myself with a little guidance. ps. i have a trip planned for sunday, so i'm hard pressed for time Thanks guys. lovetofish Link to comment Share on other sites More sharing options...

hawg_hauler Posted May 18, 2007 Report Share Posted May 18, 2007 If the impellar has broken into small pieces, be sure to watch your temperature after you install the new one as these bits can restrict water passages and plug thermostats. Link to comment Share on other sites More sharing options...

NBR Posted May 19, 2007 Report Share Posted May 19, 2007 I fish in very clear water and change mine every 3 years. When I fished in more turbid water I changed the impellor every two years. Link to comment Share on other sites More sharing options...

lovetofish Posted May 19, 2007 Author Report Share Posted May 19, 2007 I did the impeller today... No success. The impeller was badly burned to the water pump housing and unfortunately i only bought the impeller I did what i could with getting all the rubber out of the housing and i think it turned out pretty good. But i still couldn't get flow through the head of the engine. I tried first with the water ears and once in the garbage can, both with no success. I took off the bottom end after each attempt to see how the impeller was doing and it was fine. I did have water coming out through where the exhaust comes out and when i used the hose i could get water to flow through the engine and the lower unit (eliminating the chance of a clog somewhere. So i'm thinkin it has to do with the housing for the impeller or the gasket inside the housing (they must have gotten really hot when that impeller melted like that). Any ideas or thoughts? thanks lovetofish Link to comment Share on other sites More sharing options...
POLLIWOGG Posted May 20, 2007 Report Share Posted May 20, 2007 It might have damaged the shaft seal but I would make sure the pi$$er line is clear and run it long enough for the thermostat to open, it might be alright. Link to comment Share on other sites More sharing options...
lovetofish Posted May 21, 2007 Author Report Share Posted May 21, 2007 how long do you think it should take the thermostat to open? Link to comment Share on other sites More sharing options...
POLLIWOGG Posted May 21, 2007 Report Share Posted May 21, 2007 Not very long, around a min or less maybe. I had to clear the hose on my 7.5 all the time, bugs seem to like living there. Link to comment Share on other sites More sharing options...
