Carefully monitor the engine's operating temperature to ensure that it remains in normal operational range and that the

Flushing the Seawater System—Alpha Sterndrives
IMPORTANT: Your CMD Alpha sterndrive power package has the sterndrive‑to‑engine seawater supply port blocked off at the
gimbal housing and uses an alternative seawater inlet to supply cooling water for the engine. When flushing the seawater system
a supply of cooling water must be provided to both the sterndrive and the engine during operation.
You must flush the seawater system with fresh water periodically when operating in saltwater, brackish water, polluted water, or
water with a high mineral content. We recommend flushing the seawater system after each outing when operating under these
conditions. Always flush the seawater system after operating in saltwater and prior to placing the boat in storage. See Routine
and Schedule Maintenance section of this manual.
Rotating propellers can cause serious injury or death. Never operate the boat out of the water with a propeller installed. Before
installing or removing a propeller, place the drive unit in neutral and engage the lanyard stop switch to prevent the engine from
starting. Place a block of wood between the propeller blade and the anti‑ventilation plate.
1.
Drain the seawater section of the cooling system. See Draining the Seawater System.
2.
If flushing the seawater system with the boat in the water:
a.
