I have a 18' Four Winns I/O 190 hp
I have 650+lbs in the ski locker (custom LGR sac...maybe 750+... just haven't measured it yet), 350 in the bow (LGR) and may add 350 just in from of the engine later this year.
PP is 75% installed and I have a AirBoom (Roll cage or Monster next time)
PS If you do PP, talk to me first.
