Ahead of lay-up, it is important to clean the engine cooling system from salt, algae and debris to prevent corrosion damage.

Before the winter lay-up, it is also important to protect the cooling system with glycol to avoid frost damage. The “earmuff” type collars available on the market are a bit unsafe and do not always work. They also require access to a hose with running water.

This means that there is a great need for an alternate product.

The PRESERVATION KIT consists of:

• 1 custom made strong plastic sack 75 x 65 cm (width x height), which is reusable and provided with a drainage hole
• 5 STRONG-GRIP aluminium clips with roller-pins.
• 1 clamping strap 1,5 m

Do like this:

• Remove the propeller.
• Seal the bag drainage hole by means of a STRONG-GRIP wherein the plastic wound 2 times around the roller-pin.
• Attach the sack as shown on picture and fill with fresh water (or glycol mixture) from eg a bucket so that the cooling water intake is covered.
• The engine is started and allowed to idle (always follow the engine manufacturer’s instructions).
• The liquid is re-circulated through the cooling system in a natural way for the motor.
• It is important to check that the cooling water circulates and that the engine does not overheat during operation.
• Empty the sack when finished (in a vessel to reuse any glycol mixture) through the drainage hole by removing the STRONG-GRIP.

The PRESERVATION KIT can also be used for short test runs of the engine on land.

As an added bonus, the included 5 STRONG-GRIPs can be used as attachment points on the boat’s winter cover tarpaulin.
