I would like more information. Are there drawings showing how it is mounted? Does it require a different engine mount? I live in Virginia.Yep, glad you are enjoying it Gerry If anyone is interested 'over there' - its £485 or $678. The last one delivered to the US cost $730 including carriage from memory. The only alternative apart from the original (stick out the back) Rotax starter (heavier) is the GPL which weighs 12lbs and costs $800. I also offer 2 years warranty, compared to my competitor's 1 year mainly because there are M4 units ( the previous model) still operating after 20+ years!
Can I download the template before buying one?Hi Woody, it simply replaces the recoil start unit, it's no deeper, and the motor lies alongside the crankcase. No different mount required. See these pics. You can choose where you orient the motor, simply download the full size backplate template, offer it up to suit your application and mark it up based on the 12 O'clock position and we drill the plate to order.
==================We've updated several of the Rotax 447's installed on our 'pushers' with the GPL electric starter: some retain the pull start option and others didn't. They are simple to install and work fine. They are relatively heavy, a bit expensive perhaps. Out of 5 installed, we've only had one bad one. I like what I see in the M5 starter and will give that a go next time around. We are using the Shorai LFX 18 or 21 mAh batteries with a weight of about 2.5 lbs. GPL recommends an 18 amp or higher battery. So far, so good.
Well, I can tell you that the M5 can't be made much cheaper! I have to make a profit, otherwise there would be no point in producing them. I'd like to see you make one as you describe; believe me others have tried. If I could make it for $100 I would, believe me. The main pulley is manufactured on a $400k machine, it wouldn't be possible on a hobby lathe as the tolerances to accept the sprag etc. are critical. The M5 is a far more sophisticated unit than the GPL design and also lighter and far more compact. The lack of a recoil start facility has never been a problem, and on the one or two occasions someone has had a flat battery, they have actually been able to hand swing the prop (!).GPL Starter setup adapted to the Rotax 277. A guy named Monte did it years ago. He never Published what or How he did it. GPL has (3) different Starter Housings. It's been a while, but I think he did mention, he used the D4 GPL Housing. The Cover Plate could be 3D Printed today or even made from Clear Lexan Plastic. Maybe even the Housing could be 3D Printed today, at the very least be used to make a Casting. You could use Hardened Steel Inserts. The Spacer could be also 3D printed. The Tooth Flywheel you would probably have to Source unless you're a good machinist. If you look close the GPL Tooth Flywheel is made from a Flat Disc with (4) Holes and the Tooth Ring is Welded on. Both can be Water Jetted out and Welded together. There are some Billet Tooth Flywheels out there, but they're expensive. For the Rotax-based starter, setups think Seadoo's 580/587, 650/657 that used the same Horse CDI.
