Gemini 105Mc Owner’s Manual

Winterizing the Gemini

Winterizing the Gemini involves taking down all the sails

and making sure each of the water lines in the boat

won’t freeze.

To winterize the engine and air conditioner you will

need:

x 3’ section of garden hose with a male fitting

x 4 Quart bucket

x Antifreeze

x Fresh Water

This job is most easily accomplished by two persons. One

person will start and stop the engine while the second

person handles the coolant intake. You can attach a

closing stopcock male connector to the hose end as a

backup to the seacock. Fill the bucket with a 50/50 mix-

ture of fresh water and antifreeze. Attach the hose with

the male fitting to the female receptacle on the three-

way engine cooling water seacock. Turn the seacock

handle to the middle position which will draw from the

hose. Place the unattached end of the hose in the

bucket. Starting the engine will immediately start draw-

ing the coolant mixture into the engine lines. As soon as

the bucket is empty, turn off the engine by raising the

silver kill-switch.

Winterizing the Air Conditioner

Winterizing the air conditioner is much the same as win-

terizing the engine. Instructions are the same as those

covered in the Air Conditioning section of the manual—

with the exception of drawing from a 50/50 mixture of

water and engine coolant.
