Looking at the 1st pic again I think you're right.I think you're probably right about having one made to fit too-the pad doesn't look like any standard aux bracket pad I've seen.That may well be what's been done.

I am glad someone else is working on this situation. I am in the middle of doing that same setup on mine. I have a 50HP Mariner and a 4HP Mariner on the way. I found this bracket and I think it is possible to make it narrower if the need arises.

I fish a lot with two or three in my RIB. And having a reliable backup/trolling motor just makes sense.

I will post some photos of the process. I need to do some transom work before I mount the engines.

If you google Garelick, they have a fixed mount for an auxilary outboard.

Hi, i also have an older Pro 7 with a 40HP Mariner ( Yamaha 2cyl).
I tried to fix a 4hp Mercury, but ther wasn`t enough space for that little engine. The solution will be to fix a bracket to the hull and store the auxillary
engine inside. In case of trouble, you will run the engine in a blocked straght position and control the direction by the main engine with the normal steering.

Greetings from Stuttgart/ Germany

That's not very good for the tubes. It overpressurises them.
Although the webbing strap goes over the boat, it is not over-tightened. I also used padding so the strap is not in direct contact with the tubes. No marks are left - and the tubes are only pressurised prior to launching.

Worst case scenario - I could fit a bracket on the transom and store the auxilliary on-board, however this isn't ideal, especially in in moderate sea.

Thank you Mike - do you have pictures? I know the Pro (Mk 1) has a different transom set-up, but I'd be interested to see all the same.

Thank you.

Hi there.
The transom is a little different in design , but not in size.

Here is my Zodiac.

My boat should have a long shaft , however i have just bought a 3.5 tohatsu and Iam hoping that hinged mountiong bracket will overcome the problem .

The simple brackets have the most movement 370mm . The idea is that tohatsu will stay in the down position and the bracket will lift it clear of the water .
Ill know for sure when the bracket arrives , if not its back to plan 1 of removing the motor when not in use .

the guy i bought the tohatsu from used it on a shetland cruiser and said it pushed that ok even against soem tide tide tamar estuary so hopefully it will do the job because there is no way a bigger motor will fit .

Just taken delivery of my Tohatsu 3.5hp, 2-stroke, long-shaft auxilliary engine. Weighs 17kg. 4-stroke wasn't much more in terms of cost but it weighs more, is 4" wider and is likely to be more expensive to service. As space is of a premium - it was a no brainer.

The garage never stays tidy during the winter - kids eh!

I'm still investigating options for fitting it. The transom bracket (pictured) may prove key, however I think it will require modification. Any thoughts?

I'll try and post some transom shots at the weekend - so you have a better idea of the angles I have to take into account when fitting.

i found a transom bracket similar to that at the weekend , exept it has a dovetail plate on the transom end so it can just be dropped on and off . i can send you some pics of it if thats the way you need to go.

i don't even have enough room to leave the bracket in place .

Got sell the hinged one i just bought now .

I have thought about this too. I held the auxilliary engine in position on the transom over the weekend, and although it's tight there is enough space at hard-lock both ways. I plan to fit it on the port side, as I have a stern light and flag on the starboard which is all wired in.

If you were storing the engine - would you custom make some sort of bracket inside the boat? The only place I can see it would be out of the way is behind the bench seat. (see illustration)

My only concern with the auxilliary engine on a transom bracket is the vibration - coming of a big wave, etc, which could damage the tilt mechanism, even although I'd probably strap it down for extra rigidity.
