Auxiliary brackets / engine

For those of you that use and auxiliary engine this is new to me for 3003. Do you keep it on the bracket or bring it in to the rib when going along. My bracket is rated to a 20hp engine and I have a 5hp on it. Will the continual banging damage the bracket in any way, should I be lifting the engine into the boat or is it ok to leave it on the bracket.

The brackets work well on a yacht at 5 knots, but on a rib at 30 knots, hmm. This has always worried me to the point were I made a bracket and secured the engine on to the deck up the bow out of the way. The transom bracket was only to be used if we broke down.

This is what I am thinking. Ribs have a habit of falling and in a force 6 + the chances are that the forses will be sidways as well as up and down. I got the biggest bracket I could and my 5hp is very light. But will it work. Lets face it the time that I am most likly to have my main engine fail is not going to be flat calm so do I realy want to be trying to fit an auxiliary over the stern in waves. I have had one 7.5hp go swimming a few years agoand don't want to make that mistake again. has anyone cruised extensively in all weather with their axuiliary on an outboard bracket off the transome.

More theory I'm afraid...... I've heard that a good solution is to mount a hardwood pad directly onto the transom, and then to mount the auxilliary back to front on it, ie with the leg inboard and the weight of the power head directly over the transom. You still have to remove the aux. from the transom in order to turn it around and operate it of course. I imagine also that because of the height of the transom mount only a long-shaft would be able to reach the water in this configuartion .......anyone tried it???

I have fitted an aux engine bracket on my RIB.
I have an 8bhp Mariner permanently on it whether I do 1 or 50 knots.
To secure the engine so that it does not vibrate I have tied a rope from the end of the engine to the top of the A-Frame. This holds the engine tightly and had no problems (so far that is).
Many other friends of mine have done the same thing and still no problems. So is safe and provided that your bracket can hold the weight of the aux engine you will be OK.

I mount a 6HP Mariner 4 Stroke direct to the transom. I tighten the tilt fixing bolt to stop excessive bounce. Have had no trouble with over 2000 miles covered on the Rib.

You can have them for a bigger boat too.
