the 70 yamaha is a good motor 13x17 or 13x19 aluminum will work good.I think WOT range is 5000-6000 rpm so pick the one that gets you closest to high end of the scale.I used to run a boat for Sea Tow that had a 70 yam. that everybody beat the sh@#$ out of.we overheated it seized it ran it out of oil,towed and ungrounded boats that were way too big for it.and it just kept on going!the newer 70's have 'primestart' which automaticly chokes the engine so all you have to do is turn the key.No need to advance the throttle or push the choke.its a light weight fuel efficient motor

If you want to waterski much with adults, you'll regret not having a 90 or 100 hp motor, preferably one with a lot of torque (e.g., the Merc 90 with it's greater power over a Yamaha 90). A 70 hp will do if you don't want to slalom much - I would avoid a 50 unless you only want to waterski with children.

A marina near me has a used but brand new condition 2000 or 01 70 Yamaha complete for $4300 I believe. My 90 on my montauk used a 17" but gera ratios might be diferent.

Just a point of information, concerning netiquette. Using capital letters in a post is the convention for shouting. It is generally considered impolite to use all caps.
