I think they are a lot tougher than you might suspect though.

I do not hit bottom when crossing the sandbar, either with my keel or the
prop (I/O is raised). Even with a low prop speed some sand does kick up.

I guess I am wearing suspenders and a belt now regarding the impeller
based
on my terrible experience last year due to a worn one.

I'm not saying that you shouldn't. I haven't seen the need to do it
on a regular basis. Then again, I tend to use my instruments as
indicators of problems, so I operate differently than you do.

And based on your experience, I would certainly be leery and concerned
about impellers and probably do as you do - all things being equal.

On my Mariner 15 I changed the impeller after about 12 years. Major problem
was getting the leg off the O/B. One good thing about changing the impeller
every 2 years is you take off the leg and grease up the shaft so the shaft
does not corrode to the powerhead. My Yamaha T-8 is a kicker so does not
get run in the sand much and has not had the impeller changed in the 4 years
I have had it.
