I am in the process of replacing my sea water impeller on my 22 Raizor. I just took the walls out of the bilge compartment and pulled off the fuel filter. From there it was a straight shot to the pump.

Well Fellers, I appreciate the replies.......I took the seat back out and found the sea water pump impeller in perfect condition. I also back flushed the intake hose back thru the outdrive and back flushed the hose that goes out from the pump and up to the thermostat housing thru the cooler. Splashed the boat last Friday and it stays at 150 when going "coal barge" speed, but jumps up rapidly when I get up on top of the water.
I'm guessing a partial blockage somewhere......any suggestions???? Thanks I drilled four 1/8" holes in my thermostat. Dropped my hard running temps and cruising temps are more stable. |

How could something get that far to cause a blockage unless some rust? Heck, I can't see how anything got past the impeller without damaging it. I'm assuming something (trash) got sucked in thru the intake because the water is full of crap...we've had record May rains. Also, I've got Imco lowers which have a large water intake along the leading edge. Backflushing did yield one small piece of wood...........
