Watercraft Tuning Tips & Tricks

 
 
Carb tuning - Bogging out of the hole is from being too rich. if while running you hit the throttle and it dies, then your lean. the difference between rich/lean is whether or not the ski dies when you hit the throttle, sometimes its really hard to know. you can bandaid the problem by adjusting the low speed screw.
 

For Winter - Wd-40 the entire engine compartment, fog the engine with fogging oil, StaBil fuel stabilizer, Remove Battery and store in warm dry place on a battery tender.

Oil Mixture - 50:1 Oil ratio is 2.5oz oil per gallon of gas, 40:1 is 3.5oz oil per gallon of gas, 33:1 is 4oz oil per gallon of gas.
Oil - Almost any TCW-3 Oil will work. For seadoo's we recommend bombardia synthetic or mineral oil. The reason for this is that they have a different ash content that works to lube the rotary valve. For anything else you can run just about anything. Just remember, you get what you pay for and better oil will give you longer engine life. we prefer either either Maxima Marine Pro or Redline oil.
Compression testing - Buy a compression gauge. Remove spark plug wires, if there are ground lugs use them. Remove one spark plug at a time and screw in compression gauge. Hold throttle wide open and press the start button for 5 - 10 seconds. Your compression readings can vary up to 5% on seadoo's and 10% on anything else. As a rule of thumb, most 3 cylinders run about 125 psi compression and most 2 cylinders run about 150 psi compression. In some cases, a milled or high compression head may be installed and the compression will be higher. On engines with compression in the stock range, run 91 octane fuel and anything close to 180 psi needs race fuel.

After use - After riding your water craft, pull your drain plugs if you have them. While sitting on the trailer in the parking lot, start the ski and rev it 3 or 4 times to clear out any water in the exhaust. We also reccomend storing the ski with the hood or seat propped up to allow any fumes or water to evaporate.
