I have just refurbished a 40 standard shaft 40 plus with a clutch. Thanks to John at SOS for various parts and stainless nuts.
Runs nicely in a bin, not too smoky

I have a small dinghy (3m) for it to go on ahd have discovered that the seagull 40 clamp is just a touch small.
I can relieves the wood a bit but anated to ask if I can use a century bracket and mount and if the century clamp can handle a slightly larger transom and fit the 40 shaft.
Thanks for your advice.
