Finding screw for old 28 hp Evinrude 1964.

[csisommout]

Just got an old 1964 28hp,2cycle,2cylinder. Model#28402m.

Looking for L U drain/fill screw. The one comes with it does not seem to fit right.

Is there any where to buy it. modify it?. Thank you.

Is it a slotted screw or a phillips screw?

If it's the standard slotted drain screw, they're the same for decades of engines and real easy to find. Any dealer will sell em. But I'd be more concerned why it was not fitting. Is it cross threaded?

The oil drain and vent screws for that gearbox are of the straight slot variety. The one with the phillips head is not a drain or vent screw - do not remove it!

If you have already removed this screw, you may or may not have a problem, because its function is to provide a pivot point for the "Shifter Lever," located inside of the gearbox. This is the assembly that moves the clutch dog back and forth, providing forward, neutral and reverse shift postions of the dog.

Try putting the screw back in, before you do anything else to the motor. Do not move the motor at all and do not try to check the shifting function, until it is in place. Hopefully, the shifter lever (looks like a cradle with a pivoting tail) hasn't moved and you can get the screw/pin back in place. If the shifter lever has moved, you are going to have to open the gear case to fix your problem.

Always buy a factory service manual, which is specific to your motor, before attempting to service a motor that you are not familiair with! Generally speaking, they can be purchased right here at iboats. If iboats doesn't happen to have your manual, there are other online sources. Do not get fooled by the scores of bootlegged manuals available online in "CD fornat." Most of them are junk and aren't any better than the typical aftermarket manual that covers scores on motors in one document.

It is a phillip head, but it looks like pointed self tapping screw. it goes in about a turn and stick out very far.

I think, It should be like a phillip head silver color like the one is used on the gear case fill screw.

Thats not a drain screw.That holds ur gear mecinism in place.Both drain screws are slotted.Ain't going in cause the holes are not lined up.Don't run it in that condition.You may have a mess there.You got to take the prop off and get into the gear case to line it back up.

You can get the screw back it but it takes a lot of patience. Get an awl or an ice pick, get someone to wiggle the shifter and try and get the hole lined up with the pick. It works best if the engine is sideways, hole up, but sometimes that's a lot of work on the larger electric start engines. Try it, be patient, you can get it lined up without taking it apart. You cant do any more damage to it by trying. Just don't run it until the pivot screw is firmly in. Otherwise that will/can cause problems.

This is a LU from a '62 40hp. should be the same. Your screw is # 40. It doesn't show it well but it goes through the cradle, part #15 and screws into the other side so that the cradle can pivot.

And if this doesn't work, try standing the motor on it's head. You'll need another set of hands to keep if from tipping over of course. After some picking in the hole the shifter yoke should line-up.
Honestly, this worked for me, as F_R suggested this method in an old thread.

Also, send me a PM. I'll try to help you out with that manual.

I'm confused. Please look at the picture and tell us what part number you want.

Re: Finding screw for old 28 hp Evinrude 1964.

Are you talking about the screw for the shift linkage cover, their aren't many screws? Post a pic if you can.

Cisommout: In your one post, you state it is Phillip's head, but pointed like a self tapping screw, and stick's out to far. Is it by chance a self tapping screw?

Re: Finding screw for old 28 hp Evinrude 1964.

If you can, take a digital photo of the screw that you removed and the place on the motor that you removed it from. Once you have done that, please post it here. This will help us a great deal in providing the best advice that we can.

BTW, the drain and vent screws are the ones labled #14 in the diagram that jasper provided. One is located under the nose of the lower gearcase half and the other is located above the cavitation plate, towards the leading edge of the upper gearcase assembly.

It's possible someone put the wrong screw in the drain hole b/c he dropped the right one overboard. Possible, too, that the threads of the hole were damaged. You've got 45 years of opportunity to screw up on that motor.

When you get the right screw get the gasket, too.
