In addition to the annual maintenance recommended by Volvo Penta, The owner's manual says this:
Page 153:
Long-Term Storage
For long term storage (more than two months), we
recommend that you have your Volvo Penta dealer
“winterize” your engine and drive. Your dealer will
provide the proper servicing and maintenance to
ensure that your equipment is treated and stored
properly.
Should you decide to winterize the engine and drive
yourself, carry out the following procedures, in the
order in which they are listed below:
Fuel system treatment as described in Preparing
the Fuel System for Storage, page 141.
Check coolant for proper fill level and freeze
protection level. See the Service and
Maintenance Manual.
Drain water from raw water side of engine cooling
system. See Engine Shutdown, page 94.
Pump the bilge dry and air out engine
compartment.
Store battery as recommended by manufacturer.

Preparing the Fuel System for
Storage
If the boat will not be used for two months or longer,
the boat and engine must be prepared for storage.
Both the fuel in the tank(s) and the engine must be
treated with a fuel treatment (stabilizer) that counters
the negative effects of ethanol-blended fuels.
Use Volvo Penta Ethanol Fuel Treatment(4) to treat the
fuel in the tank(s). Add the treatment according to the
instructions on the label.
During storage the engine’s internal components must
be protected from corrosion. This is done by
introducing a Fuel Storage Mixture in to the engine.
Fuel treatment and two-cycle motor oil are mixed in
gasoline and then run through the engine. The oil in
the mixture coats the inside of the engine and
components with a light protective film.
See your Volvo Penta dealer to have the fuel system
and engine treated with the Fuel Storage Mixture
whenever the boat and engine will be stored for more
than two months.
The Fuel Storage Mixture is also covered in the Service
and Maintenance Manual.

Draining the Engine
This procedure covers draining the raw (sea) water
from the heat exchanger and seawater pump. Draining
these components also drains the exhaust manifolds.
This is usually done to prevent damage to these parts
during freezing temperatures.
NOTICE! Risk of freeze damage to engine
components. If the water is not drained, during freezing
conditions expanding ice will crack and damage these
components.
NOTICE! If the engine is run with these damaged
components major engine damage is possible.
Draining the coolant (antifreeze) from the engine is
only done as part of scheduled maintenance. Do not
drain the engine block for storage or freeze protection.
Easy Drain
All engines covered by this manual are equipped with
Volvo Penta’s one point drain system; Easy Drain.
The system ties all of the engine drain points together
into one drain manifold, that is actuated by a handle on
top of the engine.
The handle is located on the port-side front corner of
the engine, behind the heat exchanger.
Easy Drain can be used with the boat in the water or
on land (trailer or storage rack).
