Checking the Timing on a Watercraft

The first thing you need to do is make the timing marks on the PTO. First mark TDC (top dead center) and then mark the timing mark on the PTO or coupler. This info can be found in your manufacturers manual.

Once you have those two done you can hook up a strobe light that can work at 6000 rpms. You also need a tach so you check the timing at idle and at the specific rpm that the manufacture suggests. Now once that is set and you are ready to start the craft. Holding the timing light straight above the marks you can see the marks and if they match the TDC center mark you made on the fixed side of the cases as a reference point.

There are also pointing tools you can buy also, but as long as you have the marks where you need then you can make sure the timing is right. If the timing is off follow the instruction in the service manual to correct the problem before any damage is done to the motor. If you find a problem contact your local dealer or supplier.

Note: If you run your motor more than 15 seconds hook the flush kit up to the ski!
