Correct Outboard Size for 6 Mtr RIB

Could someone assist me, trying to understand what would be the correct outboard weight for my Narwhal 6 Metre RIB.

Typically anything from about 90hp to 150hp I would say.

Depends on the max stated number of passengers and HP that size Rib will handle according to the transom's tech plate. But if will be boating constatnly with much less the stated number of passengers you don't need to go for the full HP. A less HP motor with a maximized prop pitch will do the trick...

Happy Boating

Nice watercraft. Will it be made with PVC or Polyurethane tube fabric ? With now many souls do you plan boating with as not to go towards the max HP motor which is rated for 15 souls.

Happy Boating
