Adjusting timing 2004 60hp 4 stroke Johnson EFI

[danford1]

I have a new to me 2004 60hp Johnson EFI on a pontoon boat. It seems to run well but I like to adjust everything as perfect as I can.
I have a 2005 BRP factory shop manual. The manual is clearly intended for dealers. It doesn't give much DIY info.
It says timing is 10 degrees advanced at 3000 rpm, but doesn't say or show how to adjust it. It only says use a timing light to check it...
If I find the timing is off when using a timing light, how would I adjust it?

I can't believe the manual doesn't show you how to adjust it. Are you sure it's BRP ??

This is a sophisticated / computer controlled SUZUKI and maybe sensors look after it.----No adjustments can be made by owner ???

It is controlled by ECM and sensors...is not user adjustable.
