I'm starting to accumulate the parts and knowledge to convert my Yamaha F40 to electric start. I think it is very doable for several hundred dollars with a mix of new and used parts.
What my question for the brain trust is that I'm wondering about the utility of going full out and adding the charging circuit to the motor. The charging circuit addition requires a different stator and a rectifier & regulator and MAYBE a new wiring harness (I think I should be able to add what I need to the current harness, but I'm not that deep into the weeds yet, the new harness is $400). So with those parts, new I'm looking at 400 (maybe 800) extra or a couple hundred if used and more work (and uncertainty if using used parts vs new). I'd probably buy new parts for electrical components like the rectifier and regulator to be sure they work.
How important is the charging circuit to keep the battery topped off if I'm keeping a large deep cycle/starting battery (100 AH) topped off on a trickle charger when the boat is not in use (I do that already)? I'll still have pull start as a backup. How many starts can you get off a larger battery without charging? My guess is plenty, but I'd like input.
