Transom thickness on a Gulfstream

That suprises me that 4 stroke 200s where offered based on weights...

Mine are V6’s, and based on all paperwork appear to be original on the boat. I believe the weight spec is about 580lb ea. The newer 4-strokes are 490. Maybe that’s the difference? Still, Grady sold it with the 2003 motors attached.

Well, this just gets more and more interesting. Attached is the 2003 photo that Grady sent me, demonstrating that the thru-hulls are out of the water. Those are Yamaha V150's on there, but I don't know if they were 2 stroke or 4-stroke. The 2-stroke specs in 2003 are 426 lb ea. That's a far cry from the 583lb that my Yamaha owner's manual is showing for the F200's. What do you think happens if you hang an additional 314 lb on the bracket of that Gulfstream in the photo??
