Furthermore, it appears that the gasket between the leg and the Mercury / Yamaha adaptor plate was originally supplied in metal, but subsequently changed to a fibre one as the metal caused accelerated corrosion !!! - Guess which one I had!! - it may be worth your finding out more about this, as changing a gasket is a whole lot cheaper than what I am having to contemplate.
Many thanks for that. I certainly will have a good look at the end of the season, got to take the gearbox off then anyway. Knowing my luck...

That's a seriously good price - comes with all the rigging too, which Yamaha used to charge extra for

Ribcraft's Soozooks are cheap too, but not much call for XL 90s, which may explain why they have 2 year old unused motors in stock.
