The Boat in the Water

IMPORTANT: Flushing the power package is most effective when performed with the boat out of the water.
IMPORTANT: Flushing is needed if the engine package has been operated in salty, brackish, mineral‑laden, or polluted water.
For best results flushing is recommended after each outing and before cold weather and extended storage.
Disconnecting the seawater inlet hose will cause water to enter the bilge, resulting in engine damage. Close the seacock
before disconnecting the seawater inlet hose. Plug the seawater inlet hose immediately after disconnecting it.
