I just purchased [a 1992 Boston Whaler OUTRAGE 19] and I am looking for information on when to have [a particular through-hull drain] plug in and out, where [a particular through-hull drain] plug is, and the bilge system and how it works. Any information would be much appreciated.

Boston Whaler boats do not have a bilge. Their inner hulls are filled with foam. On the deck there usually is a small sump which will collect water. In this sump there is usually a through-hull drain. An electric pump was an option, and there may be one installed in the sump to clear it of water.

Advice on the plugs and drains is generally given in the owner's manual. I have reproduced the owner's manual for a very similar boat, the OUTRAGE 18, and you may find its advice is applicable: html#selfBailing

How much water will collect in the sump when the drain is left open depends on the loading of the hull and the static trim on the boat. When underway, water will tend to be cleared from the sump by the Venturi effect. When the boat stops, the sump will refill.

My boat has a similar arrangement, and has the optional electric pump. I keep the cockpit sump drain plugged, and use the electric pump to expel water. However, I keep my boat on a trailer and stored indoors, so there is little risk of rain water collecting in the cockpit. If you keep the boat on a mooring and rain water could collect, you may want to keep the drain open. In that way the water level in the cockpit can never rise, although the sump will constantly have water.

The sump is at the end of the rigging tunnel, and any cables running though the rigging tunnel and sump will be submerged or wet.

The pump can never remove all the water in the sump, so there is always some in there.
