Ah brilliant, thanks for the tips everyone!! Iíll definitely go for a type similar to those yellow ones. 350mm might be too big, Iíll have give them a measure at some point, but Iím sure thereíll be an alternative if so.
My transom wheel arms angle back instead of under the boat as I didnít mount the brackets low enough, but that seems fine for my 6hp. They do flex out to the sides a bit under load (or if I forget theyíre attached and lean on the transom). If I ever went for a 15hp motor Iíd need a beefier set like yours Fendlander with the lower button that the legs hook onto. Removing the old brackets and replacing them fills me with dread... what to do with the old holes!! Buy well buy once, eh...
But tbh by that point in the future a new SIB might be on the cards. I canít warrant a heavy motor for use twice a year... can I? One for another thread!
ďBut for just a few quid more we can get the next size up...Ē
