Can someone explain this?

I was reading a website from a manufacturer of all welded aluminum boats.
There is a warning on the site that says:
"DO NOT GROUND YOUR ELECTRICAL WIRING DIRECTLY TO YOUR BOAT. Direct
electrical
contact on the boat will break down the weakest point of the aluminum and
cause
holes in the boat. This is especially important if you are a SAL****ER
Boater.
This is called ELECTROLYSIS and is not a defect in workmanship or
material."
How could you avoid this? The motor is bolted directly to the metal
transom
and is grounded, there is contact there. I checked my aluminum boat with
a VOM
and there is definately continuity between the boat and the motor. Whats
the
difference in letting the motor ground to the boat and not the wiring?
What am
I missing here?
The amount of current the boat hull carries. I can get a ground from the
hull, but I run a large wire to a terminal block with ground and power.
