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.



I think this "fill the water pump with sand" is a bit over hyped.


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.
