If I am not mistaken an asd6 takes the same prop as a #6 and the reason for poor performance in reverse is the design of the prop to move water to the rear and not forward like in reverse.

Also they do stick out from the back of the boat a good ways and if you think a #6 is safe to swim around think again. Youi can build a swim platform further out to cover the props but it will stick out about 3.5-4 feet as seen in these pictures

Arnesons being Twin Disc, parts are readily available in most places. If I can find parts quickly in Europe, then you guys in the US must be able to find them in a heartbeat. It is just a question of knowing where to look. Most people can find replacement Bravo parts in a second because they have been boating with those drives for a long time and have had a chance to visit all places which do repairs and parts. A bit of quality time spent with your Arnesons and you would be able to find a quality source of service and parts. Besides, yes they do break but when they do it's either because they have not been installed/used properly or because they have not been maintained properly. As far as swimming goes, cover them with a large swim platform, like on Magnums. This is where Trimax presents certain advantages as a nicely proportioned platform is integrated in the hull design. This platform has molded steps and grabrails to help you get in and out of water, increases the rear running surface at low speeds which makes the boat able to plane at 15 mph and also has integrated ventilation ducts so you don't have to drill your SSM6 or weld tubes to your arnesons. Attached is a photo of a Trimax quad drive application. As for the mounting dimensions, there are guidelines that you can get from people at Twin Disc. It will depend on your bottom design and your current mechanical configuration. But the new ASD6 is intended to be a direct replacement for a sterndrive so in theory, you would use the exact same dimensions you used to place your Bravos. And forget about positive trim. This is not a sterndrive. They always run at a small angle, for example a Trimax is a fixed shaft which can be pre-positioned at anywhere between 2 and 8. You get to play with neg trim only... As for reversing, I've never had any problems. Yes, you are running cleavers with surface drives and maybe they are not as nimble as sterndrives but the difference, if any, is very small. It's not like a boat with Arnesons is out of control when reversing...

bouyhunter- thats not exhaust. its an air duct that feeds the prop to help free it up when planing. if you look closely at pic #21 you can see the vent on top of the trimax drive also. defenitly interesting how the need air to get the prop to bite properly.
