>>>How dare ye abandon the world of 2-smokes!
Well yes indeed. Funny thing is the more I looked into this Suzuki 20EFI the more I realised the ideal SIB engine was a last of the Mariner/Mercury/Yamaha 15hp 2-stroke models.... and that I had a minter one of those in the garage already.
But I was on a downhill slope with no brakes so it's happened anyway!

That's interesting as I was wondering about making something that would both take the outboard and alternatively hook into the bow handle of the Aerotec so it was held off the ground then when taking it along the road for a distance you are not trying to lift with your hand awkwardly behind you and pull as well.
Something similar would do the trick.
