fly wheel rotaion direction

[mntboy]

58 johnson sea horse 35hp. Which way should my starter suppose to turn my fly wheel? Does it matter?

it always turns the flywheel clockwise. the bendix turns counter clockwise in order to do it.

Re: fly wheel rotaion direction

why does pull starter turn it the opposite way as electric starter?

If you are saying it has a pull starter and an electric starter turns it in the opposite direction, you have an add-on electric starter that is not the right one.

The electric starter turns counter clockwise and turns the flywheel clockwise when the starter gear hits the flywheel ring gear. Basically a gear to gear deal. The pull starter spins clockwise since the pawls engage the flywheel on the top of the flywheel.

Re: fly wheel rotaion direction

so my fly wheel should be turned clockwise with the electric start and counter clockwise with the pull start? All i know is you can crank mit right now with either electric or pull starter.

No. Any starter, manual OR electric should turn your flywheel CW.

If you are saying it has a pull starter and an electric starter turns it in the opposite direction, you have an add-on electric starter that is not the right one.

That assumes that noone has changed the rewind starter to something not-standard....

Can i have the starter rebuilt to turn the other direction. I cranked the boat with it turning clockwise, will this "F" up my motor?

Re: fly wheel rotaion direction

The motor is supposed to rotate clockwise at all times.

You may have your battery cables reversed; be sure to have negative ground.

That's what I was going to say, cables sound reversed. Any electric motor is capable of spinning in either direction, all depends on cable polarity.

Re: fly wheel rotaion direction

If the starter mtr has permanent magnets in it for field coils, Yes it will rotate in either direction depending on battery polarity. But if it has wound field coils in it as most old mtrs had, battery polarity doesn't make any difference. Will still rotate in the same direction The only way you could change the direction of the old mtrs was to change armature or brush plate position.

Take an old starter on the bench and try it. Bet it rotates the same direction either way.
Come on, you know you want to......

Sorry about the double post. Hit the wrong buttons.

Re: fly wheel rotaion direction

hold on. If your cables are reversed, or for any other reason the starter motor spins opposite the way it was designed for, the bendix will never rise up to engage the flywheel. It can't, because it's on a threaded shaft.

I know this because I once reversed the brushes in the brush holder during reassembly. The motor bench-tested fine. Clockwise, which look ok to me. Spun like crazy on the motor but the bendix wouldln't engage. Scratched my head for an hour or so fore I figured it out.

besides which, didn't you say it cranks fine either way?

reread dhadley's post above, it's the most clear explanation you'll find:

The rope start engages the *inside* rim of the flywheel, so that mechanism turning CW makes the flywheel turn CW *with it*.

The electric start engages the *outside* rim of the flywheel, so it spins CCW and makes the flywheel go CW.
