Rotax B8ES Spark Plugs

How often are you all replacing these? I have a Rotax 447 and I am replacing the plugs after what I assume was 30 or so hrs. Probably don't need to as the plugs look ok but I don't know when the owner before did them.

 

Michael Coates, you may know mate, what is the recommended replacement by Rotax?

Agreed... 25 hours sounds good, especially if the engine is inverted.

Not inverted but I have been advised 25hrs so that is what I shall do :)
