Bought a ski in Nov 13'..........August 2 2014 ski is finally running good! Bought a ski and had it shipped. Paint was in bad shape, turf was also. Turf came off, sand the paint. Found foot holds leaked, ride plate mounting screw stripped, impeller hammered, pump damaged, pump seal bad, intake grate damaged. Handle pole was covered with carbon.....poorly. Numerous non stainless parts installed and rusting. Repaired, replace, repainted, re-turfed. Try and ride when spring time comes and runs poorly. Re-jett from seal level.....Ride.....Run poorly. Coil is bad....replace. Ride, tune, runs better, but poorly. Stator bad....replace. Ride, tune......runs better but still poorly. New CDI, carb rebuilt kit, ride, tune.....runs poorly. New domes, shorty cone......ride, tune, runs poorly. Try tuning pipe, jet works flow control, ride, tune.......runs poorly! At this point I am determined to get this thing running. I find versi plug leaking, and numerous exhaust leaks. Fuel lines bad, tank with crap in it. Replace fuel lines, clean tank, fix exhaust leaks, change popoff, re-jett, ride..........runs poorly! Now we are into July, I have been on the lake a dozen times and the turd is still not running good. Low end still has a rich bog and the topend is running out of fuel! Its rich and lean at the same time! I try giving it what it needs and on my last ride in July it drops a cylinder. Compression check and one cylinder is reading zero. At this point I say forget it. I am calling Jetmaniac and ordering a new motor with new carbs! Pulling my old motor apart I find evidence that it had a major air-leak, is my guess. Moisture in the stator and oil all over the stator. Also found my pipe had almost rubbed a hole in the side of the hull. Should of pulled the motor in the beginning and done a leak-down test. I decided to completely go through it. Everything I should have done when I first bought it. Repainted the inside of the hull. Found more exhaust leaks. Pressuried my pipe and found that one of my water fittings was not working correctly. Tuned the pipe hooked up to a water hose. Jetmaniac sent my a 781BB with new carbs and stock intake setup, with his best guess for 5000'! One week later I installed and took it to the lake. Its now broken in and jetting was about 1/4 turn on high screws off. Oh.. and the idle was off by only a quarter turn! JM knows his stuff. Super impressed! I don't fault the seller of the ski in anyway because this is used Jet Skis and I wasn't buying new. I experienced what you would call cascading failures. Hey, its August and I am starting to ride my ski now! If anyone needs a Ported 735 with ADA head and stock 38 carbs that, "needs a little work" let me know! I don't know how many times I keep saying "Stupid Jet Skis" but I guess I enjoy the challenge.....sometimes! This is the third used ski and they have all been turds when I get them. I don't know why I keep expecting something different. It is nice once you get them running good though!
