150 Johnson Timing

[dartman]

What idle and WOT timing spec for a 2003 150 Johnson? Do you need a special OMC tool, or can an automotive inductive type timing light be used?

You can use a timing light but it may interfer with the electronic eye. The electronic box is the best thing to use.<br /><br />I believe 20 is the wot timing. That may not be right. There should be a sticker on the plastic housing.<br /><br />All this is assuming its a carb'd motor.

Where can one buy or rent the OMC electronic box?
