The angle will work just fine, checked that out before I got it. The sceptre has a angle of 13 degrees (some say 14 some say 13 mine measures 13). The dusky bracket has an angle of 12 degrees, more like 12.25 degrees so it will be close enough to use. The less than one degree will just let the swim platform have a slight angle down towards the motor. So small you wont notice and it will help the water run off the transom. I have read you can use a bracket at + or - a degree with no worries.

Good to hear that ! Glad it worked out

It hasent worked out yet, angle looks good and it seems to look like it will fit fine but it is mighty heavy. The tub is two inches thick with two 5/8 layers of glass with a 3/4 wood core between them. Took a lot of weight off by getting rid of the splash well and cutting it down but hopeing that the large flotation space will make up for the extra weight.

After seeing Bigshrimpins bracket lift (floor jack adapter) I had to make me one. It will help a lot to have something adjustable under the bracket while test fitting it ect. I could not find a pipe or rod to fit the jack so I had to turn one down on the lathe. Once I got that done with that I welded it to a plate, drilled it so that I could screw it to the bottom of the jig I made yesterday. The jig is a small pallet with two bunk boards on the top for the bracket to rest on and the whole thing sits on the jacks arm in the same hole the cup uses.

That's a really stout looking bracket! Any idea what it weighs after all the trimming?

I think you'll want to mount it as low as possible to get maximum flotation at rest. I think Don Herman mounted mine so bottom of tub is about 4" above keel. Motor AV plate is 3.5" above keel in attached pic. We redrilled the holes to raise it another inch, but it still needs to come up about another inch, because AV plate is still under water when up on plane, so keep that in mind when you drill motor mount holes. I need to make an adapter/spacer plate because lower bolts will interfere with the swim platform if I raised them another inch!

Yea it is defiantly stout! A little too stout! It is around 140# right now but the tub is cut to 24" height and I will lower it down to around 21" or so and that will get it down to the 120# mark I hope. There is a lot of thickness were the splash well was molded in at on the last 2" that will be coming off when I cut it down three more inches and that will help shed some weight. I will be putting some back with the swim platform so not sure what the final number will be but it will be a little heaver than most. I got core-cell foam to core the platform with to save on weight and the bracket will have tons of flotation so I think it will be fine. The flotation tub goes all the way out to the end of the second step almost.
Mine will be mounted at around 4" up from the keel to keep the tub in the water as far down as I can so it will have maxim flotation and no drag on plane. The bolt on lip is facing outwards instead of inwards so 4" is the low as I could get it.
Far as the motor mount, I haven't cut it down yet due to wanting to get it right. The bracket is a 24" set back and with a 25" motor I figured setting the mounting tab at 27.5" (2.5" higher for the set back). Everyone says a inch per foot of set back so that is 2 inches plus I will add a 1/2" to that and may need to go even more. Everyone also says they have to raise there motor up more so I may start at 28"-29" mounting height and them go from there. I will be easy to cut it down more but going up not so easy.

What height do all you csc guys think I should set the motor at to start with for a 24" set back???? The help is appreciated.

Making a little progress on the mold for the swim platform. The weather slowed me down a bit with the tropical storm moving threw but still managed to do a bit today. Primed with high build primer ready for glass tomorrow.
