engaging the transmissions.
GAUGES should read as follows:
Oil pressure about 60-70 PSI or 5 bar. The engine temperature should rise slowly and settle at no more

than 180 F or about 80
Note -- If oil pressure is low, shut down engine, and inspect engine compartment
and look for possible cause (for example, loss of oil.)
overheating or there is lack of raw water expelled in the engine exhaust, stop the
engine immediately. Recheck the raw water-cooling system to ensure the seacock
is 'open' (handle in-line with valve). Next, check the raw water strainer for debris.
Remove the strainer, clean, re-assemble, and reopen the raw water intake valve
(seacock). Restart the engine and re-check water flow from the exhaust. If water is
not flowing properly, the RAW WATER PUMP may need to be serviced. Seek help.

Running the Engines

After the engines have been run up to temperature for a few hours you should "run them hard" for 15-20
minutes at 2300 rpm. Believe-it-or-not, doing this helps the engines, makes them run cleaner, and makes
them run more efficiently.

Shut-Down

Before shutting down, allow the engines 'idle' for about 5 minutes to cool them gradually and uniformly.
Usually, this can be accomplished as you enter the marina and head for your slip. The time engaged in
preparing to dock the boat is usually sufficient. Ensure each GEARSHIFT is in the "neutral" position and
each THROTTLE is in the "idle" position. Turn off engines by depressing the start/kill switches next to the
keys then turn the keys to the off position.
