This time this ski came to Doctor for 150hr medical checkup.

Engine room condition is very good , no rust ,no corrosion.

This ski didn't turn starter motor because starter solenoid terminal was broken.

Won`t engine keep run of Kawasaki STX 12F, 2

All fuel drained from fuel tank.

After drained all fuel then filtered and found a lot of water. It was 700cc of water sitting on bottom of fuel tank!!!!!!

This is main cause of this ski's problem.

Won`t engine keep run of Kawasaki STX 12F

This ski had problem which won`t keep run. It was engine start but stop immediately at any time after strat.

Checked fuel pump performance.

Test results was satisfied.

But found a little water from above test.

I will check fuel tank and report tomorrow.  

Found something inside of water box of GP1300R

I heard something noise from inside of  water box. It was more noise when shaking. I found something inside,,,,

It was broken pieces of catalytic converter. Must be this motor`s catalytic converter was broken before and then change to fit D-plate instead of  catalytic converter but didn`t check well left of broken pieces when replaced parts.

A piece of broken core of  catalytic converter

Water box hole repaired by weld.

Water leak from water box of GP1300R

Water box sitting just under the battery box.

This is water box and bottom of barrel was damaged.

The barrel has 2 of deep line damage and big hole.

Why water box was damaged because protection rubber was missing on top of trim tab fitting insert nut bracket. In short water box sitting on top of bracket directly for a long time because damaged and got hole. Since this ski got hole of water box always water and exhaust gas leak from that hole, must be ski runs bad also lucky ski didn`t sink.

Another funny news of this ski I will report tomorrow.

Water temperature sensor problem of GP1300R

This ski came up warning sys on and now won`t start.

Ski checked by PC diagnoses and found problem. It was water temperature damaged. After replace sensor engine was start and not come up warning sys on  but I found another problem which water leak from rear of exhaust sys (under the battery box).

I will check that tomorrow.

Engine damaged Kawasaki STX1100

Customer said engine won`t turn.I thought impeller locked by cause of impeller housing becasue I disconnected jet pump unit but still engine won`t turn.

Next step, check spark plugs. #3 spark plug was very dry and gray color,in short this mean something happened #3 cylinder.

I found a few of  looks like roller bearing of small end or big end at front of  flywheel cover.

Picked up and checked, I was convinced these are part of roller bearing.

I found more damaged broken piece between crank case and engine bed. In short damaged piston or connecting rod smashed crank case.

So this ski decided to go wrecker with out dismantle motor because cost to much for rebuild motor.

This ski was 13yers old and had been used 258Hr.
