DESCRIPTION

For rinse-, glycol- and dry-running seawater cooled engines.

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.

SPECIFICATION

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

HOW TO


  • 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.

Our fenders (unless otherwise stated) are shipped deflated to save you money on shipping costs.

For next day deliveries, orders must be received before 11am.

Boat Fenders Direct delivers great service with quick delivery and excellent product quality.

Ordering online was simple, and their team promptly addressed my query about delivery times. Even when stock issues arose, they ensured timely delivery to an alternative address. Friendly and responsive staff made the experience smooth. Highly recommend!

The service is good, delivery is really quick, and the buoys are excellent quality These buoys last a long time too and the clouds don't fade.

My rowing club (on what is effectively a ship-canal-type-of-river) uses long lines of them on a rope to try to prevent rowing boats in races going down the side channels to the weir by mistake (remember: people rowing racing boats face backwards to the direction the boat is heading; they are supposed to look over their shoulders every 3 or 4 strokes, but sometimes forget). So we need bright red buoys!.

The buoys I ordered were securely packaged and arrived well within the promised time frame. Great service that I would use again.
