Q1: what is the part number for a replacement [through hull drain fitting] for a 2003 SPORT 13?

BACKSTORY
The previous owner stored my recently-acquired 2003 SPORT 13 boat in a “high-and-dry” [probably means rack storage], and the boat was rarely left in the water. Since I have owned it, I keep the 2003 SPORT 13 in the water for a couple weeks at a time. I notice it develops a starboard list as it sits [in static trim].

I assume [the cause of the static trim list to starboard is because] the [through-hull drain] fitting under the helm is leaking and maybe the stern [through-hull] drain leaks, as well.

Q2: what drains are you leaving open when [the boat is] in the water?

In my experience the SUPER SPORT models never really sit level at rest. With the battery and helm on the starboard side that might be causing the list.

I usually leave all plugs in.

The boat does always have the list to starboard as you suggest.

I first thought that was just the way the boat [settled at rest], but [the list to starboard] gets worse over time.

Eventually the boat will no longer get up on plane, so I am assuming it is getting water logged.

You can get a replacement part from your Boston Whaler local dealer.

If you local dealer is not interested in helping you, then contact Sue Lodel, the parts manager at a long-time Boston Whaler dealer who is interested in helping owners. See

I am not certain what type of drain you are asking about for the c.2003 13-footer. If the drain is a brass tube, you can get information about replacements in the FAQ. See

If the drain is made from a plastic, you may have more trouble in the replacement process. Read in the forum archives at

If the hull weight has increased due to ingress of water into the interior of the Unibond hull, that would be a more or less permanent weight change, not something that could come and go depending on how long the boat sat in the water.

Once water gets into the foam in a Unibond hull, it is not coming out at the same rate as it went in. Removal of water from the interior foam of a Unibond hull tends to be a long process. For some background read the FAQ at
