Rebuilt motors

[Sgt Wagner]

Just purchased 2-2001 Kawasaki 1100 ZXI PWC. Both motors have been rebuilt and I have paperwork on both. They both run and need to be broken in. How should that be done?

welcome aboard.

for break in, follow the process just like it states in the operators manual.

this is for 2-strokes

None of the jet-ski engine break-in steps can be done with the jet-ski out of the water. This condition applies to all models of jet-skis. Jet-ski engines that are improperly broken in due to negligence or by attempting to break them in out of the water can experience loss of power, frequent shut-offs, reduced performance, piston ring failure, and even piston seizure.

DI model jet-skis should not have any oil added to their fuel tanks.

For jet-skis that utilize an oil and fuel pre-mix system, the oil to fuel ratio should be enriched to a ratio of 32:1 for the first ten gallons of gas that is run. If the jet-ski is equipped with an oil injection system, then a 50:1 ratio of fuel to oil is recommended to be run through for the first ten gallons.

Upon initial startup, let the jet-ski idle for ten minutes to allow the engine to warm up and to allow oil to permeate internal gaskets and engine components. During the initial ten gallons of fuel being run through the jet-ski, the jet-ski should never be operated at full throttle. Doing so can potential cause damage to piston rings, pistons, and engine cylinder walls.

Begin cycling the throttle from idle up to 20% capacity and back down to idle for a full half hour while riding. Bring the jet-ski back and shut off the engine to allow it cool for at least half an hour.

Restart the jet-ski and bring the throttle to 50% capacity for a full half hour while riding. Bring the jet-ski back and shut off the engine to allow it to cool for at least half an hour.

Restart the jet-ski and bring the throttle to 90% capacity for a full half hour while riding. Bring the jet-ski back and shut off the engine to allow it to cool for at least half and hour. Repeat the process of riding the jet-ski at 90% capacity for half an hour and letting it cool for half an hour until all ten gallons of fuel are gone.

Never hold the throttle at a static level for more than a few seconds ? it is important to cycle the throttle as much as possible during the engine break in period.

After the first ten gallons have been depleted, replace the spark plugs in the jet-ski with new plugs. Restart the jet ski and operate it as you normally would for the entire second tank of gas without bringing the throttle to 100% capacity for more than five seconds at a time.

Once the second tank of gas has been depleted, your jet-ski is broken in and you may ride it to its capacity.

Now that deserves a sticky!

Thanks you. Looks like I also need to get an owners manual.

Do you know why they needed to be replaced to begin with? All too often, something else is wrong (like a lean carb) that causes the engine to seize. If you just replace the engine and run it, you'll end up the same way.

If the carbs have not been done recently on those engines, it would be a great idea to get them redone so you know the won't be causing a problem

btw... +1 on Scott's post!!

Took them to a shop. Carbs on both skis need rebuild. Didn't realize they were so expensive to have repaired. $750 each. Thank you.
