No problem, do what you think is best. It's your boat. I will probably
be up on the trailer next week for my 2000 hour and I
will post a picture of a 1700 hour impeller running in the water I
posted the other day. I am still holding 3 PSI at idle and 17-18 at
4500. That is pretty much what it did new so I bet it is not that bad.

gf,
I am glad you have not had any problems with your impeller, and I hope
your luck continues. I follow the mfg'er recommended schedule in
changing the impeller, oil and outdrive fluid, and never worried about
about the few dollars it cost. All of these are very easy DIY projects.
It was very cheap insurance. I have never had an accident in my car,
nor have I filed a claim on my homeowners insurance, but I would not
consider discontinuing my insurance.

For what it is worth, here is the recommended maintenance schedule:

While they recommended changing the impeller every 100 hrs. I only
changed the impeller after the first 100 hrs, then decided I could do it
every other year.

At the very least, I hope you are pulling your impeller and inspecting
it on an annual basis. If not, I hope your luck continues.

PS - When I am crammed into the bilge on a hot July day changing the
oil, sweating my ass off I really wish I didn't change my oil every 50
hrs, but since my boat has over 1000 hrs on it, and I have never had an
engine related problem and it purrs like a kitten, I will continue to
change the oil every 50 hrs. I normally run my engine at 3400-3600 rpm
depending on the number of people on board. I change the oil in my car
every 3000-3500 miles, and my car engine normally runs at 2400 at
highway speeds so it is comparable to the way I service my car. Since
the boat will sit for days without being used and will run for long
periods at high revolution it is more important that the oil is in top
condition.
