Auxiliary engine on Zodiac 4.7 Pro

Anyone got an example on how to achieve this as the stern has a lip on it and with a 40 hp gives very little room to attach a bracket.?

Thanks

Read this: https://www.rib.net/forum/f36/fittin...pro-23132.html

Fit a solid extension bracket. Do not fit, repeat, do not fit an adjustable bracket - it will rattle like a Vauxhall Viva on a frosty morning.

Reckon you should be able to squeeze an auxilliary on there, but do your measurements before you drill holes or order the auxilliary engine. Width of the cowl will determine, with main engine on hard-lock.

One last thing - tether the outboard underway in the up position, there's a fair degree of vibration at the stern underway, unless you want to gift your new auxiliary to Davy Jones's locker.

Hope Rebekah Vardy is ready this too!

I have just done this on my zodiac pro 420.
I bolted a piece of wood wide enough for the auxiliary bracket onto the transom,tight to the top edge.
I found the flap of the tube where it is strapped to the transom was in the way. I glued a large D ring onto the tube and then fitted another d ring to the inside of the transom so the tube can be secured by that. I will also use the original way but not tightly if that makes any sense.
I can get photos of it next week if it will help.
The auxiliary is a tohatsu 3.5hp.
I haven't used it yet but it might be better removed from the transom and secured when not in use.
Definitely worth having as I had engine failure the last time out with no auxiliary motor, luckily for me I got a tow from a passing fishing boat.

Would be interested to see pictures. I had the same engine on my Zodiac Pro, assuming 2-stroke.

BitsNPieces, my advice, where possible have the engine in situ. I’ve seen auxiliary engines stored in front of a console or lying on the deck, but when you need to use it in anger, then it needs to be easy to deploy and start. You really don’t want to be trying to hook up an engine in a F6.

The tethering part locks the engine in the upright position underway. I do the same with my Mariner 4hp. The strap goes around the engine block and exits through the pull start on the cowl. From there it connects to a stainless steel U bolt on the transom knee. Ratchet tight.

Last bit of advice. Treat your auxiliary like your main engine. Even if you don’t use it, flush it with the main engine after a day out and service it regardless of hours. The tell tale on small engines is prone to blocking so carry strimmer cord in your tool box, especially in salt water. Renew starter nylon rope /cord every couple of years.

I've got one of the Trem adjustable brackets and I don't think it makes any noise in either its up or down positions. The benefit the adjustable bracket has is that I can have my auxiliary tilted down all the time, which I'd read was the better position for it to be in when bouncing around on the transom.

Probably a bit late but here are some photos of my auxiliary outboard.
Hopefully the pictures upload.

You will want to get that exposed transom glassed up. That bare wood will wick moisture and will weaken integrity of transom.

Looking at picture 1, isn't it just a block of wood sat on top the transom to raise the motor a bit?

You could be right, but what exactly is holding the main engine on? I count two lower bolts on the transom saddle.

Honestly it’s like a job for Poirot!
