Are you doing 12" extension boxes and keeping it side by side? Leaving the transom straight no notch?

yes , yes and yes.


Mocked up:

Dan if I am seeing correctly in your mock up the prop shaft is level
with the hull. Given the stand off box would you not want it 1 or 2 inches above and space down if need be. Just asking. Rick G.
I know you are talking to team Archer he knows his **** .

Actually 3/4" above the bottom when cross referenced propshaft and centerline.
So the final resting place will be 1.5" above that making the drive 2.25" above bottom.
That`s the best part about a soggy transom, you can drill holes and mock things up and if it`s off that`s all good, it`s getting replaced anyway .
I talked to Dan once he does know his stuff that`s for sure!

Side note, I was using a level on the bottom in the past trying to figure out X dimension and I was wrong all these years . The laser is so easy to use and accurate.

Oh, yes!

Hey Dan,

In moving from the SSM 5 to the SSM 6, how does that change the cutout and bolt pattern? Wondering if I can mate up a 6 drive to my boxes...

I know you're replacing the transom and starting fresh, looking for info on changes needed.

Can someone post a SSM5 template and a SSM6 template / print? Bolt pattern with dimensions?

No you can`t , the bolt pattern is different as is the cutout as is the transom assembly.


Dropped off 2 weeks ago ... some progress .

Right, I get that Dan. I would have the option of welding up my boxes bolt pattern, and re-drilling it to match the #6 bolt pattern transom assembly.

Do you have the #6 pattern just like the #5 pattern you just posted? That would tell me how much modification would be needed. I have "#6" boxes but drilled for a #5 drive (or enough real estate to land the #6 drive and bolt it up). It may not be as bad of a switchover as I originally thought. Running drivelines and drive shafts now. I saw the prop shaft to drive shaft input dimension is within a 1/16" from a 5 to a 6. That makes the install pretty simple for me, just re-drill a pattern (and all the hydraulics. But all of that runs through the box for me right now anyways, so no real transom work needed.)

Unsure if my transom could handle the forces though. It was built pretty stout as-is with the #5s on boxes setup. What's minimum reinforcement, transom thickness, or any bracing required for the #6 setup?

Also, I have 3 sets of 4 blades and 1 set of 5 blades if you need any for testing.
