Post Outboard Starting.

Do marine outboard engines need a starter ring gear?
How is the cranking with a rope is done, does it have a Starter ring gear?

Outboards with electric start will usually have a ring gear. Pull starts have pawls that rotate out to engage a notched pulley/wheel attached to the top of the flywheel when you pull the starter cord. They retract when the flywheel spins faster than the starter cord wheel.

example: part 3 engages part 21, bolted to the flywheel when you pull the cord

Haven't checked lately, I would assume electric with no pull has been appearing on smaller and smaller engines. Our club had a 40 hp that was only pull start years ago and a 50 hp that had both. I was able to pull start the 50. At the other end I've seen 9 hp engines with electric starts.

There has to be 100s if not 1000s of models of outboards that use a ring gear.
Look for engines with electric start then see if you can find what kind of starter it uses, if it has a pinion it's almost positive to have a ring gear.

It's been years since I worked on one of these, I'd forgotten about it. This is a kind of a ring gear for a pull start

I would guess at least 90% of the electric start outboards have a fairly traditional ring gear. I won't say 100% because there's always some oddball out there with their idea of a better mousetrap.

Here's a result of a google search of: yamaha outboard flywheel ring gear diagram

1992 40MLHQ Yamaha Outboard ELECTRIC STARTER (40ER 40PR) Diagram and Parts

Pick an engine, any engine with an electric start and check it out.

Re: Outboard Starting.

Besides that most of the electric started ones up to 60hp have an emergency manual start.(Yamaha always) Usually a v groove in the flywheel. Then you have to take the top cover off and manually wrap a rope around the flywheel. But at least you have back-up.

It would be more of a challenge to find those companies that don't offer an electrically started outboard. Off the top of my head I can only think of two(and one of those is bound to offer it I. The near future).

Re: Outboard Starting.

Could you fill us in on why and what this information is going to do for you? I'm pretty sure than even tiny 8 and 10hp models can have electric start as option. Many small outboards might not come with ring gear as a standard, unless electric start is ordered. at some point the ring gear is standard on all engines. Are you looking to buy a new outboard? Or need a ring gear for a science project?
