Alpha or Bravo Models Using Alternative Water Pickups
A water inlet block-off kit must be used if the sterndrive unit water pickup will not be used
to supply water to the engine. When installing the block-off plate, it is necessary to cut the
water hose that is located between the bell housing and the gimbal housing. This allows
water to continue to circulate through the sterndrive unit for cooling.
CAUTION
Avoid overheating sterndrive. The seawater inlet holes must be allowed to flow
water without being obstructed or overheating damage to sterndrive may result. Do
not dead-end seawater hose from bell housing. Cut hose as recommended in
procedures.
1. Remove the existing water fitting and gasket. Discard the screws and washers.
