The tow eyes are rated to hold 2.5 - 3 times your boats weight
The talon bracket will rip off the boat from the forces of a tube
A tube that gets submerged will go from 400# of force to 2500#+. A 3 person tube would impart more force
Products like turboswing or rent a boat
rinda and vessel view are looking at the failure prone sensor

OPs engine is a Mercruiser SBC 350 reman with anywhere from a 0.020 to 0.060 overbore sold as a "357" so it could be a 352 cube, 355 cube or 357 cube. Unless you look at the reman tag, neither you or I know the displacement.. you are arguing for the sake of arguing
Manuals are copyright material so I can not share them in open forums
Manual 17 lists 150 psi cranking compression for the small blocks with 9.4:1 CR
Manual 18 list 180 psi cranking compression for the 4.3 with 9.4:1 CR
The difference is the cam timing
That and 40 years spinning wrenches you...
