So far I have only found 1 brand of surface drive strut hardware, the Speedmaster.

I'm just curious to know what others make such hardware. Application is for a 1/4" drive.

Thanks

Octura, Warehouse Hobbies, Top Secret Boats, Aquacraft, M&D Designs, Aeromarine and Accu-Tech (I think that's the name) right off the top of my head.
Most of my boats from nitro to gas have Speedmaster hardware hanging off the transom but I've also used Top Secret more lately.

And the price is right at Bill's Top Secret Boats.

Have used ALOT of top secret hardware and love it had an issue with a part I bought from them and they took care of it very fast and very friendly people to deal with.
