Photos as promised. It has a modification to it to tilt the whole bracket up a bit, as it tilted back too much on my transom and I couldn't get my aux out of the water (the lifted position on the aux was only a few inches higher than lowered. The mod is a pair of stainless plates (red outline) on the mounting bracket but they can easily be removed if needed.
It only has 2 mounting bolts but you will probably want new anyway as mine are trimmed to fit my thin transom.
The bracket has 5 positions. It has only been used on about a dozen trips but has been sat in a pile of dust in the barn to looks scruffier than it is.
Similar ones on ebay go for anything between £70 and £120 + p&p new. Make me a sensible offer and its yours.....
