Trem auxillary bracket

If you have one of these brackets fitted as a back up for main engine, do you keep the engine on it (3HP) or do you store it in the boat. Just wondered if it would damage transom when bouncing around as the bracket seems sprung loaded?. Cheers

Used to have something similar (Plastimo) on my Zodiac Pro. You need to secure the auxilliary outboard with a ratchet strap under tension or it will rattle like a bag of spanners.

I use one of these:-

OUTBOARD ENGINE BRACKET AUXILIARY 35KGS 15HP STAINLESS STEEL BIRCHWOOD PAD | eBay

It locks solid.

I have a lifting one with a spring, however it also locks on a screw (the spring is to aid lifting only). Its like the ebay one but without the mounting plate angle adjuster (which looks good actually!). It may be fine for a yacht but in rougher seas in the up position it bounces around and I'm concerned it would eventually fail. The clearance on the bolts that form the pivots for the linkage is enough that in the fully up position there is free play. My fix has been to lock it in the half way up position so that the linkage makes a rectangle, not a diamond, and is much more rigid. I then chock the aux up with a bit of wood and strap it down solid.

I have yet to see what I think is a suitable lifting aux bracket for a powerboat. I don't fancy lifting an aux onto the transom in a pooh/fan moment, so go with the best I can find.

It's not fun when an aux bracket fails on you at speed at sea. I was very lucky!

Make sure and aux bracket has bolts and not welded pins. And even then be wary, check regularly for ware etc.

That's good, so it ok to keep on the bracket but making sure its it is secure. I was worried it could damage the transom.

Might clear a 9 inch-I'll measure it for you when I'm next down at the boat.
