STERNDRIVE WATER PICKUPS

There are two types of water pickups available on Mercury MerCruiser sterndrives: dual
water, and side water pickups. Dual water pickups require the flushing attachment (44357Q
2) and the flush seal kit (881150K 1), and side water pickups require the flushing
attachment (44357Q 2).
Dual water pickup
NOTE: Flushing is needed only for salty, brackish, mineral laden or polluted water
applications. Flushing is recommended after each outing for best results.
Flushing the engine with the boat in the water can cause seawater to flow into the engine,
resulting in engine damage. Close the seacock before flushing the engine. Keep the
seacock closed until starting the engine.
1. On seawater cooled models: Proceed to Step 4. or Step 5.
2. On models with the sterndrive seawater inlet blocked, supply water to the sterndrive
and to the engine. See Alternative Water Pickups.
3. On models using the sterndrive seawater inlet and a through‑hull or through‑transom
alternative water pickup, supply water to only the sterndrive by taking the following
steps to block, or disconnect and block, the hose from the alternative seawater pickup
pump inlet Y‑fitting.
