Changing Impeller for Yamaha 150HP 2-Stroke
I heard something about the need to change the cooling water impellor at regular intervals on outboard motors. I am fully aware that inboard/outboard outdrives need to have impellers changed with regularity, but this is the first I’ve heard about doing it with outboards.
I have a 2005 Yamaha 150 horsepower 2-stroke (model 150D) outboard, and I saw nothing in the maintenance chart about changing the impellor. What do you all know about impellors and Yamaha 2-stroke outboard motors (or the need to changes impellers with regularity on outboards in general).
Once again, thank you all for any help and advice.
