Guys, about how long do impellers last? I know some replace them every year, which I'm sure is the right thing to do, but does anyone have any idea how long one lasts?

change it every year, and you'll be good to go. From what I understand, sitting during the winter is harder on them than when you using the boat. I went two seasons on my first one, and never again. It was pretty trashed, and I really don't know how the boat didn't overheat. I always keep a spare with me just in case.

Basically till the engine overheats! There is probably no way to guesstimate the life of a impeller, because there are so many variables, so..................................replace every year unless you are experienced in a quick change on the water and carry a spare, of which everyone should do!

Cool, thanks guys........TMC#1, on the last thread we talked about yesterday, about the engine temps I had this past weekend.....I've been pondering it, and come to think of it, the impeller in there now is about 3-5 seasons old, and I'm thinking that's why my motor ran a little hotter this past weekend than it did last year. I'm just hoping that's what's wrong with it!!

Just did my annual change ... 10 minutes top once you get the hang and the right tool ... angles neegle nose vice grips for me

I would go ahead and change the impeller and I'll bet your temps get more stable and the heat up after pulling a skier will go down somewhat faster. Mine goes to 170 or so after running hard and stopping to idle, then drops back down to 145-150 in probably 3-4 minutes tops.

3-5 seasons is pretty long. Like TMC said, I'm sure you'll see a difference after changing it

I was just talking to a fellow MC'er who replaces his impleller every year. When he winterized last year, he noticed his impleller was missing some vanes :eek:

That impleller was less than 1 year old.

My point is, you never know how long they sat on a shelf, or other factors which may lead to pre-mature failure. When they fail - it's too late, as then, you have pieces throughout your engine.
