So I found this, no clue what it is.

Out of curiosity, what does the cutout on the outside (toward the engine control panel in your photo) fit on the boat? Is it the right shape for the aft corner or swim platform of your transom? I'm thinking that 8" is too small for propane, but what about the top or bottom of a dive tank? Looks like it is made of Starboard. Any wear on the surfaces, or fasteners to secure it to the boat?

8" is a great fit for the guard on top of a propane tank.. the center-to-center distance is about right for the smaller tanks 5-10 pounds. Thinking a bungee from bottom across the middle and down would hold two 5# tanks

I'll add my guess - was the previous owner a diver - some sort of stabilizer for a couple of dive tanks.

View attachment 135515 I found this part buried in a locker on a new to me 2006 H38. Anyone have an idea?
On our boat (2005 Hunter 45 CC) we have a propane locker outside on the port side of the cockpit. The locker holds two separate propane tanks and the piece that you are asking about fits down over the 2 tanks, separates them and helps to hold them in place. Hope this helps.

Alright, alright now. Not everyone wins something they want every time.
SHEESH! Must suck where you're from... in most of the Good Ol' U.S. of A. ..... EVERY kid gets a trophy! Even the losers!
;)

I still think the photoshopped image with the instruments in it PROVES I'm right and I DEMAND MY TROPHY!
.
so... does this have any edges/ledges on the side we can't see in the pic?
How about screw holes?
Might it not even belong on the boat?

It reminds me of something that needle workers use to hold their yarn.

Similar item came with my new 2007 41DS in the propane locker. Keeps the tanks from moving around in the locker.

Like I said on a previous post. Previous owners put things on boats before delivery to mess with our minds
YEAP ... and I'm still giggling about the odd kitchen gadget I stole from my wife's gadget drawer at home and threw it in our previous boat after survey!!! ;)
