Bubba going to need to change out the water pump on my Yamaha 2000 model 25 hp 4-stroke. Have changed out lots of them, But never on a Yamaha or the 4 strokes. Anything different on one of these? This one has never been changed. But I also never turn it over dry also. I think that is why people have trouble with there water pump. Turn one over without water and your asking for trouble. Or I can let you change it out at Pickwick? And film it with my camera? Also will be time on the 140 Suzuki 4-stroke next year.
