Not sure a rib is the best option.. Just bought a 4m with 60 2 stroke, actually tomorrow will be the first ski attempt.. So far the wake is quite small.. I was luck to get a ss plate reinforcement on the transom with tubes bolted to the floor.. Very strong ski bar.. But interior space is a small issue.. Bonus is I can pop on plane instant cos ribs are light!!
For 3 ppl mine is a nice size.. Just enough room for everything plus beers
Look into the mercury spitfire 4 blade props.. Better holeshot and grab.. Plus they retro fit onto any motor.. Received mine last week, very happy so far..
