I did mine 2 seasons ago. I favoured the port side and used loads of sikaflex between the shoe and transom and also between the backing plate and transom on the inside. Bolts only minimally tight to hold everything in place, wait 24 hours, then tighten fully. Clean up any squeezed out sikaflex straightaway. Everything worked great, but I had some of Scotland’s finest anyway! I use a Suzuki 2.5 4-stroke. Vroom vroom!
