Thicken epoxy for quick spot hold then 5200 the rest
Old skool RTV silicone,if you ever need to remove the shoe for any reason.Dam,you guys are brutal with some of the sealants you use.Just go buy a chisel and sawzall for later removal
Silicone was used for 20 plus years without issues when properly applied.What happened!?

Bag of Quickrete from home-depo aughta do it. Seriously though any flexible adhesive that doesn't mind getting wet will do. Keep in mind it's sandwiched in between the hull and pump pretty good. Take your time and make sure the surfaces are surgically clean and send it.

100% silicone adhesive (clear) for me. I'm not a fan of 5200 for a whole bunch of reasons. 5200 as an adhesive to me is like wrestling shoes as a riding shoe is to me. Over hyped and wrong for the application.
I have used 5200, haven't tried to remove one with 5200 yet, I might regret it if I ever have to. I removed one that someone else installed with thickened epoxy and the joint between the epoxy and the shoe was completely loose, it was only held in by the mechanical interlocking of the shape. I think it's too stiff, something more flexible is better.
Next one I do I might use regular silicone.

Whatever I have available at the time. Last one was microballoons and epoxy and it worked well.
I'm interested in the reasons you don't like 5200.

Back in the old days the pump shoe was also part of the pump, not seperate like they are now.

technically could move some when the pump is installed. Or intake grate putting pressure on it pulling it down and lose......

It's polyurethane based so its acclaimed 'flexibility' deteriorates over time especially if exposed to UV. It's not viscous enough, so it runs like a MF'er and makes a mess. It's adhesion qualities and vibration resistance is over rated. I've had 3 bilge pumps come free from my hull using 5200 to bond them down. I've never lost one in 15 years using 2 part marine epoxy. Plus if you ever have to remove it, good luck, unless you have some DeBond and a weekend to kill.
My plastic shoe was installed with epoxy. I Was nervous too remove it during an upgrade and possibly damaging the gel coat or hull.....
Turns out silicone breaks down when heated and releases and epoxy breaks down when heated To just over 200 degrees with a heat gun...
I got the shoe out without any damaged to the hull or gel coast using the heat method..

What's this about silicone breaking down now? I have an x2 with a stock pump so I'm always interested in any way to remove silicone more easily.
As far as epoxy...if the hull is made with epoxy resin, seems dangerous to heat the pump shoe to a temperature that would soften epoxy.

“Technically” anything can happen,but for the most part l haven’t had any issues with rtv.And don’t say cause l don’t keep a ski long enough
