Starboard Pull-Out Strength

[boatnamesue]

I've got a mini stern saver fixed to my transom for transducer.  For those unfamiliar with stern savers, it's basically a square piece of starboard 3/4" thick.  Anyway, I want to use this stern saver to secure my bait pump, but I want to be able to remove pump when not in use.  The bait pump has a backing plate with 3 slotted holes. 

I was thinking to under drill 3 holes into the stern saver 1/2" deep, screw in 3 large head screws with flat washers.  When using the pump I'd slip the backing plate under the screw heads into slots, then snug down screws. 

My question is....will the repetitive turning in and out of these screws (1/4" at most) cause the screw holes to become "stripped" or lose screw bite over time?  Or is starboard so durable that it won't be a problem?

Why not use say 3/16' stainless nyloc nuts & bolts with the bolt countersunk & inverted?

I may have just answered my own question. The starboard is already attached to your transom isn't it?

The Starboard is kind of soft.  My guess is, the screws would eventually wear out the hole.  You could always instal threaded inserts like these: https://www.boatoutfitters.com/8-32-press-in-threaded-insert?gclid=EAIaIQobChMI3ubr6e2O2wIV3rjACh2M6QHSEAQYASABEgLM2PD_BwE

Indeed it is.  But that's a good idea had the starboard not been fixed to transom.

Fantastic!  First I'm learning of these inserts.  Put a dab of 5200 in the starboard holes to firmly secure inserts in.  I'll look into these, thanks.

Oops, disregard my last.  Just recalled that 5200 doesn't bond with starboard.

You can actually get a good bond useung 5200 with Starboard.  Just rough it up.  I’ve even used a table saw to kerf the back of Starboard blocks for mounting accessories.  It also helps to pass a torch over the surface of the Starboard, not enough to melt or char, just to alter the surface for bonding.

Good to know, thanks!

Thinking more about your suggestion here ^^^, despite the starboard already fixed to transom.  Let's say it wasn't fixed and thus had access to the transom-side of starboard.  I countersink the bolt head into the starboard on transom-side....when I go to lock down the nylon nut won't the bolt head turn as I apply clockwise torque to the nut, even turning by hand too?  Since it's a bolt and not a wide pitch threaded screw, I would think the bolt will spin freely, no? 

How about a hanger bolt for such an application?  Certainly won't spin.

There is also a stud you can get that has wood screws on one side and machine screws on the other side.

No reason they wouldn’t work.  You could also use t nuts from the back of the block.

That's what I mentioned in my previous post, hanger bolts.  Gonna give these a go.
