So your computer water pump is gimpy.... heard it all now...
Those impellers should be changed every spring. I do mine myself. It is easy, but I only have simple motors 25hp and 40hp Evinrudes. I watch my flow and as soon as it starts being eratic I change the impeller.
Glad you had a good trip and only missed a little fishing time. I went the day after we spoke on the cells. We did okay but didn't really get them biting untill we had to leave. We caught them in a creek channel 20' open area and then fished one of my condos in 24' water where we had the best luck of the day. I love those condos. Maybe we can get a trip in in april.
Tightlines to ya.
