Transom too thick for auxiliary

[MikeSmith1]

The transom on my rib is 60mm thick and I noticed that a lot of auxiliary sized engines (4hp-10hp) wont fit on it. The clamp brackets wont open wide enough to fit. I checked a 5hp Yamaha and it seems to open around 58mm which is slightly too small. Has anyone had this problem before? Do the clamp brackets some in different sizes?

I know I could attach an auxiliary bracket but I'd prefer to just mount the engine straight to the transom if possible.

Agreed, I had this problem and it was about 2mm that was the issue.

I took a grinder to the aux bracket and removed some ridges that took it back just enough to squeeze over the transom. Sounds a bit scarey but really not that bad, I just painted the bare metal where I had removed the ridges.

+1......stealing millimetres here and there with an angle grinder last two boats. Even the cup washers on the clamp screws. How hard would it be for the manufacturers to make the clamp a couple of centimetres wider. I think all the Tohatsu based Merc/Mariner 4/5/6HP use the same bracket and it's the same as the old two strokes. Even if there was no clamp and it had to be bolted on it would be better.
