    Default Lesson learned with aluminum impellor

    I normally use a stainless impeller but switched to an aluminum one after the river season to run in the salt lagoons, normally no scarping bottom. Well I ran up the river and scraped a little and sucked up some of the bottom, I decided to check the impeller and had to get creative on removing it! A come along, a rope tied to the impeller, sledge hammer and a truck bumper is what it took to get the dang thing off. Just a FYI.

    We can't use aluminum cam locks in our brine facility at work for the same reason your prop was so difficult to remove it does something to the metal almost fusing parts together turns into hammers and frustration and broken parts
