A small trick we use on Pacemaker to make sure the optional weight is correct is to mark all our optional items with tape and write the weight on it.

For example, the outboard has it’s fully fueled weight written on it.

This helps us work out what is required on board for racing and roughly how much it weighs when we get to the next regatta.

 This is the photo of my battery installation in AUS174. It s a jumpstart battery pack bought on special for $39.00

We modified it for use on the boat by removing the jump start leads, installing a ON/OFF switch shown on the right.

The unit has a cigarette lighter socket on the right for your external power out connection.

The unit is mounted under the sink and tied to the forward bulkhead  using 3 stainless steel saddles . The main advantage over a stand alone battery is that the enclosure houses a battery metre, a low voltage indicator, and a 240VAC charging pack.
