Starter Diagram

[ImgMkr3]

Many thanks for the info on the firing order on my 70.

Now I've got a question that's gonna be stretch.

I need a diagram of how your basic outboard starter works.

Long story short I think the bendix on my starter locked up. I've read the principal on how this thing is supposed to work but I'm trying to figure out what should be moving up to engage the flywheel that isn't. If I grasp the armature and lift up on the gear it won't budge. Nothing moves and there's no way the armature itself is moving.

Hopefully a diagram will help my mechanically challenged mind to grasp how this thing is supposed to work.

Thanks in advance,

Not much of a stretch at all.
You gotta try harder than that to stump us.

Re: Starter Diagram

Many thanks Supreme Mariner, never thought I'd wake up this morning and see a diagram. This is amazing.

Now I'm going to expose just how little I truly know (but at least I'm honest) 8)

OK so part 14 which I don't know the name of...(is this the bendix or just a part of the assembly?) It appears that under pressure (i,e,, if I pull up on it) it should move upward. Then the spring pushes it back down when the starter switch is turned off.

The reason I ask is that if part 14 should be able to move in the assembly then I've found my problem with the starter.Right now nothing on the entire armature will move. It's locked up hard.

Having said that I'm off to buy a new starter I guess.

Thanks again for all the time and trouble. For a newbie this place is like finding the leprechan's pot of gold.

Re: Starter Diagram

Every part of that starter can be bought separately from Mercury.
The entire starter is $220.
Iboats sells one for $155.

Part 14 is called the pinion, or "starter drive assembly" in the parts catalogs.

You might want to try a couple drops of PB Blaster and gently tapping on it with a screwdriver handle.

Re: Starter Diagram

You don't pull up on that pinion (bendix) It is on a spiral on the shaft. When the motor starts spinning, inertia causes it to rise up the spiral and engage the ring gear on the flywheel. To check it you need to spin it up. Before you buy a new starter, take the old one apart. you may have a little rust inside on the armature which can be lightly sanded or the bearings may be dry and need oil. I have had them so tight, that they couldn't be turned with a wrench yet after a little PB or WD 40 they became serviceable. Give it a try--you have nothing to lose

Re: Starter Diagram

you might also want to consider bringing it to your local starter/alternator repair shop....i've had 2 different starters rebuilt at mine at it comes back from them in new condition with a 1 year warranty for $95....anything goes wrong with it you bring it back to them for free...

Re: Starter Diagram

Thanks again to all who posted. The suggestion of hitting the pinion with a hefty shot of PB and letting it sit for a minute did the trick! Took a hefty twist to get it loose but once I cleaned it and lubed it again it's back to normal.

Between the advice on the firing order and the help with starter I've got the boat purrrrrring again and she's up for sale.

When I get the money for this one I can dump it into more goodies for the party barge!!!

Thanks again to all! The advice we can get up here is the only saving grace a "poor" boat owner's got.
