Engine codes, tips, DIY’s

[Winerocks]

I think it would be very helpful if we started a sticky page with information like this for Scarab owners. Many of us are no longer under warranty, or prefer to fix things on our own. Following are codes, some of which do not apply to our boats. These are CEL codes for Rotax 4-tec engines.

Agreed. These codes should be at the top.
