Oh so many jokes - so little time.

WAY too much class. :)

When you're in water shallow enough to kick up sand, why not jump out and
pull the boat in? You shouldn't have any problems standing in 2 feet of
water!

If I got out and walked everytime I was in 2 feet of water I wouldn't
need an engine ;-)

Note: zoom in and how far you can still see birds walking around. You
could walk to Mound Key (on the right) and never get your knees wet.
This is 3 feet at high tide, noted on the stick in the top picture.

Jim was talking about running through sand to get to his favorite beach. If
the water was that shallow, I'd get out and pull the boat rather than fill
up the water pump with sand.

But, I'm very weird. And, in the minds of many, an asshole.

I assume those are Roseate Spoonbills mixed in with the Ibis?

I think this "fill the water pump with sand" is a bit over hyped.
Certainly if you are stuck and grinding your way out, you are pumping
a lot of sand but if you are underway in shallow water the sand is
going out behind you.
Backing down is worse than going forward because that puts your water
pickup behind the prop.
You should still not be running with your prop in the dirt, simply
because it tears up the grass but if you can jack your motor up you
can run pretty shallow without hurting anything.
18" of water is plenty for me to go withouit leaving a mud trail in my
wake.

Ah - but I can think of one situation - sand on the ramp.

We have several launch ramps in the area what are sand traps because
of the water flow. If you have a drive on trailer, that can be a
problem.

Admittedly not much of one, but still.

What I *know* is that John did not comprehend what I said.

Let me repeat.......I need to back over a sandbar to get to the beach.

Oakland Beach launch over in Warwick on the Bay. One whole side is
virtually unusuable because of the sand drift from the bay and harbor
which is a huge sand trap.

I know exactly what you are talking about.

I cannot jump out of the boat to pull it to the beach as once over the
sandbar I am in water over my head for 30 or so feet. Although my IO is
raised, I still kick up a lot of sand when passing over that sandbar.

Heh - if you run the Connecticut River down by East Lyme that happens
all the time. Heck, at the mouth of the river is a huge bar with a
breakwater/cut channel at Saybrook Point - great fishing though.

The water pump is not filled with sand but there is enough sand to act as an
abrasive on the impeller.

Hmmm - You would have to really spend a lot of time in a sand bar to
get that kind of abrasive action - in particular low speed.

I have seen a guy literally downsize his prop on a sand bar though. It
was pretty funny.

Hey - if it makes you feel better about your engine, go for it.

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

More experienced boaters understood what you meant. Anyone who has
fished the flats in Florida and who has had to motor slowly over skinny
water to get to a channel gets it.

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:

http://idlezone.com/html/boating_faqs.html

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.
