No room to move engines up and forward. Extension box needed so a driveshaft can be used and engine can stay in place

Did you buy the jig plates? Very nice, I think I read Glass Dave had some.

If you want the propshafts 2” below the bottom set the crank centerline measurement at shaft to shaft +2”. The boxes move the drive straight back, they look like they have rise in them, but that accounts for the 13* transom angle so the drives don’t end up lower.
2” above sounds like a good spot for them, the Old School top gun with a notched transom was 1” below the bottom, transom notched, no boxes and had no issues getting on plane. I was trying to talk Kevin into going up 2” with that setup when he had it.

OK ! I'll do it Jamie! I'll do it!

Make sure you calculate your driveshaft angle if can't move the engines, it may dictate how high you can go.

Transom to propshaft is 5'.. that`s going to be out there ... these #6 things are heavy, gotta somehow mock this up on theboat https://cimg5.ibsrv.net/gimg/www.off...c619802a3b.jpg

Several top guns had 6’s on boxes. I had an album stored in one of my old phones of all the ssm 6 guns.

5’ from transom to leading edge of propeller?

To the end of the propshaft.

F6- Speedy, I`ll have my guy do the "racelayup" Glass Dave special on the transom
