I finally got a 14x13 3-blade on my 2014 ProStar. Previously with the 4-blade, I got 39.3 top speed at 4460 rpm and full throttle to get a 220 lb skier up. Now it goes 41.9 mph at 4800 rpm. A 200 lb skier seems to need less throttle. and at 30 mph he is at 3380-3400 rpm which is largely the same as before. A 180 lb skier at 34.2 tachs at 3940-3980. No noticeable difference in the wake or rooster tail. I haven't done the math yet, but there's got to be a lot less slippage (more bite) with the OJ 3-blade SkiPro. May be a little more noise, but I had the carpet out

Chuck, I'll be watching for your results on the props. Top speed, tach readings, and pull-up acceleration. Thanks in advance. Bob

My 5.7 ProStar has the 13.25x14.5 four blade OJ. Top speed is 39.3 at 4460 rpm (630 ft altitude). A 220 lb skier needs almost full throttle to get up. A 200 lb barefooter drops it to 37 mph. He's ok, but prefers 38. Has anyone tried the 3-blade 14x13 or any other prop? I want to get a spare anyway, but don't want to make a mistake.

My very cooperative dealer & I have tried 3 different senders & are now waiting to hear back from MC. Since this is my hobby, I put together a temporary one as a "patch" that worked well over 2 tanks of gas. I used a Teleflex swing-arm kit cut down to 5.5 in and reversed the rheostat. Then put a 1 W 400 ohm resistor in series with the 12v supply. This makes the sender produce 0-5 volts and the computer happy. I really don't recommend this. Took a few hours & 2 trips to Radio Shack. More fun skiing & pulling skiers. Video of wake at 38 off 34 mph was awesome (not me skiing)!

Fuel senders used to a bulky swing arm float that operated a resistor. Later compact tubes were developed that created the resistance with electronics. To connect to the newer computers (Why?) the sender needed to produce 0-5 volts. Looks like boat mfgr's went to a tube that relies on the small pressure created when inserted downward in the tank. Problem seems to be that with time & sloshing, the fuel creeps up the tube and we're getting low readings. I hope somebody's working on this.
