678999 is not a valid engine serial number (it must have seven digits!) Can you check it?

Mea culpa. Engine no. is 6759989.
On the Type C gearbox inside the housing halves are raised numbers "6810021" and "6810011".
Also, on the prop side half are raised numbers: "94 (encircled) 1286" while the other half has "05 (encircled) RX01 SCF". However, hand etched near the edge is "KF 74".
Rotaxese is a difficult language to translate.

6759989 was produced 08-Jul-2008
Engine Type: ROTAX 582 UL Mod.99
Model Number: 395820010
Original Factory Configuration:
with oil pump
with rewind starter
with 2 Bing-carburetors 887833
water outlet socket bent
That engine doesn't have additional sub-assembly part or serial numbers listed , so I can't tell you the original gearbox it shipped with (on some engines we have this information available, but not this one).
"6810021" and "6810011" are actually the part numbers for the gear housings
(properly "810021" and "810011"...)
Sorry I can't be more helpful, but that's all that the factory database has for you on that engine.

Re: Finding gearbox serial number via engine serial number
by Ronen Shtekel » 7 years ago
Our 912ULS 100 HP engine serial number is 5646675. We would like to know the gearbox serial number that was originally fitted whit this engine and the serial number of the replacement gearbox. Our main gear (the larger one) serial number is 061314, should it be the same as the gearbox serial number?
Thanks for your help
