    Default Ignition system correction

    Apologies all; The Firefly ignition is an inductive ignition system (not CD).

    Default End cap work

    The top end cap was machined and now sports the Firefly pickup stator installed. Images also show the rotor that includes 5 magnets. On the bottom end cap, the two original front mounting bosses were removed, and a new one welded in place to match the second block. This week, the ignition coils and rotor will be fitted. It turns out, Firefly creator Matt Richardson recommends the ECU be mounted in the boat to avoid vibrating critical components.Name:  Pickup.jpg

    Hi Tim, is it the Michigan air that brings out the MAD MACHINEST in you and Dick Austin ? Looking forward to the results of both of you.

    Hi Al, Pretty sure Dick and I have the corner on the radical outboard projects business lately. The site is not letting me load images, but the oil pump & methanol tank have been fitted, and the rod pivot pins tack welded. Tim

    Default Mock up looking good!

    If BRF is behaving itself, images of the 888 mockup are attached; looking vicious! This is the extent of my work until fall due to an impending move. Look for updates in September. If all goes according to plan, the completed 888 will be displayed at Mark Suter's October 2016 AOMCI meet. Thanks for your many helpful comments and suggestions. Best regards to all, Tim

    BRF not behaving today....... I'll try different methods for posting over the next few days. Stay tuned.

    God help you! I'm in the process of completing one myself (after 36 years in the same place). A nightmare!

    Likewise..... 28 years here. Moving the machine tools, fixtures, engines, and parts is way worse than the house!
