I have RDE-17 parts list.
But I do not have parts list for RD-17
I would like to make a RD-17 into electric start.
Can I bolt on a ring gear to the flywheel that came with the RD-17.
Or do I have find a different flywheel.
I do not own the RD-17 yet. I am gathering infoSeptember 12, 2019 at 11:25 am #183180The RD-17 (rope start) did not have a ring of any sort, so no you cannot bolt a ring gear on. That is assuming the RD has the original flywheel.

September 12, 2019 at 12:33 pm #183189Ok follow up question-
The part number for the ring gear of a RDE-17 is 203486
The part number for the ring gear of a RDS-20 is 203486
But both have different part numbers for the flywheel.
On the parts list (Marine Engine.com) for the RDS-20 it shows the type of flywheel that accommodates a generator.
The RDS-20 flywheel I own does NOT have the spot that accommodates a generator
Drum roll
Can I use the RDS-20 flywheel which I own on a RD-17 to help make it electric start????????September 12, 2019 at 12:35 pm #183190Ok follow up question-

The Johnson starter mount is rare. Many of us older collectors are tired of pulling on a rope and would rather just push a button.
September 13, 2019 at 9:47 am #183235Will a flywheel from a RDS-20 work on a RD-17 ?????????
The part number for the ring gear of a RDS-20 is 203486
The part number for a ring gear of a RDE-17 is 203486
Both are the same
The RDS-20 flywheel which I own does not have generator ribsSeptember 13, 2019 at 10:14 am #183241According to the quick reference chart, yes.. 580336, 580337 fit RDE-16 thru RDE-19C and RDS-20 thru RDS-21B. Note that they don’t include the rope start RD-17. That might be because of other things such as recoil starter clearance etc. That, I can’t answer.
BTW, the generator pulley always fell off those things. SNAFU design.
September 13, 2019 at 12:04 pm #183251How do i get on of those quick reference charts
September 13, 2019 at 1:54 pm #183255e-bay. That’s where I got mine anyway.
