lopster3 yes I halve lookt at the video I need to no ware o tds shod be at idle with timing light

No not at idle.
The static timing can be done while not running.
Otherwise the motor needs to be running with a load on the prop and operating at wide open throttle.
This means running the boat at wide open while operating a timing light.
This also means the motor/prop is right and will reach 5500rpm's at wide open.
This is real dangerous and can be tricky.
The static timing is relatively easy.

One of the top posts in the forum is a post on setting timing.
​Setting it at idle while running you can be as much as 30d or more off????????
The post covering static timing is what you need to do.

You can damage the motor.

Timing an outboard in NOT like timing a car.

Please wright your posts with punctuation marks and comma marks. It is almost impossible to read and understand you. It will make it alot easier to understand and help you.

When you set the timing on most OBs you set it at WOT. It is fixed at idle.

Most Chrysler/Force OB have 30dgr advance BTDC at WOT dynamic. If you set it static it will be 28dgr BTDC.

Dynamic setting is when you run the OB at WOT in water at the right rpm and under load.
Static setting is to set it when runing with starter motor or if it has points setting it with identify when the points start to open (no runing motor).

Dynamic setting is the best for proper setting/tuning.
