DRAINING INSTRUCTIONS

CAUTION

If boat is to remain in the water, seacock, if so equipped, must remain closed until engine is to be re-

started to prevent water from flowing back into seawater cooling system. If boat is not fitted with a sea-

cock, water inlet hose must be disconnected and plugged to prevent water from flowing into cooling

system and/or boat. As a precautionary measure, attach a tag to the ignition switch or steering wheel

with the warning that the seacock must be opened or the water inlet hose reconnected prior to starting

the engine.

IMPORTANT: Observe the following information to ensure complete draining of cooling system:

• Engine must be as level as possible.

• A wire should be repeatedly inserted into all drain holes to ensure there are no obstructions in pas-

sages.

1 Close seacock, if so equipped, or disconnect and plug seawater inlet hose, if boat is to remain in the water.

2 Remove and drain the following:

A The end covers from both the port and starboard sides of heat exchanger. Drain tank completely.

IMPORTANT: Use compressed air to blow any remaining water from the tubes in the heat exchanger.

B The drain plug on the lower side of the engine oil cooler.

C The aftercooler drain plugs located on the starboard and port aftercooler side covers.

NOTE: Only the port aftercooler side cover is shown. Starboard is similar.

3 Repeatedly clean out drain holes using a stiff piece of wire. Do this until entire system is drained.

4 Remove seawater pump outlet hose from top of seawater pump and drain.

5 Disconnect seawater outlet hose at bottom of exhaust elbow. Lower hose and drain completely.

CAUTION

Avoid water entering boat. Do not unplug seawater inlet hose unless a seacock is present and it is

closed.

6 Remove hose(s) at seawater strainer and drain hose(s) completely. Remove drain plug and empty seawater

strainer. Reconnect hoses - tighten hose clamps securely. Install drain plug and tighten securely.

7 Make sure that the speedometer pitot tube, propeller plate cavity vent hole and drain passages are unob-

structed and open.

8 After seawater section of cooling system has been drained completely, coat threads of drain plugs with Per-

fect Seal and reinstall. Tighten securely. Reconnect hoses. Connect hose to seawater pump outlet (top) and

hose at exhaust elbow. Tighten clamps securely. Tighten hose clamps securely. Replace end cover gaskets and

seals, if worn or deteriorated. Install end cover assemblies on the heat exchanger. Torque the end covers to

120-132 lb. in. (14-15 N·m).
