I've been playing around with this on and off at the shop. The intention is to be able to change out different tuners without having to pull the whole engine apart. Just pull off the lower unit and loosen the tuner bolts. Here is what I have designed and machined so far...

NICE work there Kevin.

You guys sure don't waste any time lol. 3 replies before getting all the pictures up.
I just have to finish making the tuner and a flange for the water pipe. Not sure when I'll get to testing. It would be nice if I could this season. Have to see what happens...

Thanks. It has a second set of holes so that you won't have to remove the powerhead bolts to take the wingplates on and off. Also, the thickness is the same as a stinger adapter plate so you don't loose driveshaft engagement like a normal 56 adapter plate. It has tapped holes on the front for the steering arm so no need to make up solid mounts either. For all I know, I could be wasting my time with it. In order to get the bolts out, I'm probably going to have to use socket head cap screws, and use a hex bit with a ball end to loosen and tighten the bolts as I'll need to get on them at a slight angle if using a tuner that has the same size at the end as an SST-60. I couldn't make the flange for the tuner any bigger, or it wouldn't fit out the bottom of the mid. Also, I've read there is so much vibration there that bolts will easily come loose. I'm hoping if I use lock washers and blue loctite every time that the bolts will hold. I've found that in this "Sport", you just have to try things for yourself and see what happens. If testing goes well and everything works as I want it to, I will make some of these to sell if there is any interest.
