I received an email from Paul Chernikeeff at Rotec Aerosport who gave me permission to share the details on their alternator kit for the Rotax engine.

Hi Brett,

Our Rotax kits are not so well known but they do work great.
Our Rotax alternator kit has a large pulley that slides over the Rotax prop flange drive dowels and center spigot. The pulley gets sandwiched between the prop and flange and is 5 mm thick and so would push the prop forward the same amount.
The kits are well received and work perfectly.

Will be interesting to see if it fits inside the ss7 cowling.
If I get one, I'll post a thread in the Product Review section.
