How often do you change your raw water impellers for your motors?

Every 2 years, especially if your boat goes in shallow water kicking up
sand.

I ahve mercruisers, and the alpha1 is a fairly simple procedure to
inspect and change out. I look at mine every couple years. When I got
my 23' Marquis last year, I pulled the bottom leg right when I got it
home after purchase (in late fall) , and looked at the impeller while
winterizing the boat.. It was getting some wear. So I left it apart,
and this spring installed a fresh one and re assembled the lower
end.

Like I said, it's not difficult at least on a Mercruiser. I'm not
familiar with other brands though.

It used to be easy on outboards. Not so easy anymore.

JimH knows the dangers of not changing his impeller, it can result in a
very expensive mistake if you don't change them biannually.

Every two years, unless I'm operating frequently in shallow areas, then
every year.

1973 Evinrude 115: Last changed in 1992.

1981 Evinrude 115: Last changed prior to my purchase in 1997.

1972 Johnson 6: Never changed since new. This one gets the most use.

purchase in 1998.

On the latest Yamahas and I assume on other brands, you can get a
cooling water pressure display on your multi-function gauges. My guess
is that if you know what your pressure usually is under varying
conditions, you will be able to tell when something is amiss, such as an
impeller going tits up. Maybe. :}

An inspection port would be nice.

Mine is stainless, and I sharpen the leading edges once in awhile. but it
is a jet drive. My Outboard kicker about every 3 years. I look at the pee
stream also.
