Hi Frank,
When you figure the diameter of the shaft
and the diameter of the shaft fitting, that the shaft goes into, there is only a
difference of like 50 thousandths of an inch. Even if you forgot to put
the O ring in that fitting, it's not like going to be Niagra falls coming into
your boat. You could probably put some bubble gum on it and the leak would
stop. You would be able to address a problem like that as soon
as it occured. The hydrolics would add too much of an extra thing for
me to deal with. I wonder if there is a way to smooth out those cast
fittings so they could be polished? I will probably put a T into my
ballast vent valve inbetween the valve and the ferro body for HP air. It
would be nice to have a LP air generator for "topping off" the
ballast air so as to float yourself higher on the surface. I seem to
remember the Tang would do that to try and get maximum speed on the
surface, they would run the compressors into the ballast and the exess air
coming out the bottom of the ballast would cut down on the friction
against the water. giving them an extra knot per hour speed.
