Mounting the pump
Models 401 C, 403 C, 405 C, 401 STC, 403 STC, 405 STC
•
Drill a 1” diameter hole through the transom or hull bottom. If drilling through
the transom, make sure the hole inside the boat is beneath the waterline
outside the boat when the boat is standing still.
•
Place the pump into the hole with the gasket in place on the inside of the boat.
•
Tighten the nut on the outside of the hull until you are sure the gasket ring
is tightly sealed. Be careful not to overtighten. Make sure outlet is at least
parallel with boat bottom. This helps prevent airlocks.
•
Saw off the excess length of the pickup tube so it is flush with the outside
surface of the nut. In the event you are using a strainer (Rule Model 73), leave
1/2” beyond the nut. Make sure the cut is square and the threads deburred
to allow the debris strainer to fit smoothly.
By lifting the locking ring, you can rotate the position of the discharge nozzle so that
the discharge is facing toward the tank (see diagram below).
