Underwater Thru-hull Fittings
There are three thru-hull fittings in all boats fitted with a "Y" valve system. Each fitting has a ball
valve that can be opened and closed. The ball valves, at an absolute minimum, should be opened and
closed at each 100-hour servicing. They should always be left closed if the boat is to be unattended for
a long period or if there is any danger of freezing. Once again, this is a minimum requirement. Some
people argue that the valves should be closed whenever you leave the boat.
Useful Tip: Whenever you close the engine thru-hull fitting (raw water intake) drop your engine
ignition key over the ball valve handle. This way, when you retrieve the key, you will always remember
to open the ball valve before starting the engine.
Transmission
You can check the transmission oil level by taking out the screw- in dipstick on the raised portion of the
transmission housing. See the engine manual for details. Check the oil level by inserting the stick
without screwing it down. The oil should be clear. If it is cloudy or milky, or if the level is
too high,
you could have water entering from the oil cooler.
Water Tanks
The water tanks are situated in the engine room ahead of the fuel tanks on both the port and starboard
side. Since the water tanks are made of a translucent plastic, the water level in each tank can be seen
from the engine room. The tanks may be filled from either side deck if you open the supply valves at
the front of the tanks. However, it is quicker to fill each tank from its own deck fill. You can reach the
deck fills from inside the cabin through double sliding side windows.
Webasto Furnace
It is wired directly to the house batteries and not through the main power panel. Be sure to turn the
furnace off when leaving the boat -- turning the battery switch off will not stop the furnace from
cycling on and off. In all boats the furnace will sense if the house batteries are low and will shut itself
off automatically. Even though the furnace shuts down, the batteries will be in a discharged state when
you return to the boat. If you don't get back for several days your batteries could suffer serious damage.
If you choose to leave your furnace on low as a backup during cold weather, do so only if you are
confident that your shore power is reliable and be sure your battery charger is on. The furnace is very
economical and uses a negligible amount of fuel.
If you like to get cozy and raft up to other Camanos, keep in mind that the furnace exhaust is located
on the port side just slightly ahead of the cockpit. If you don't keep a safe distance from the furnace
exhaust you could wind up with blistered gelcoat on some cold night. We have found strategically
placed fenders do a good job of protecting the hulls of visiting boats.
A FINAL WORD
At the risk of annoying you, we wo uld like to close with the three most important recommendations in
the handbook:
Never Operate the Boat With the Hull Port Lights Open.
