Anyone know why the text font is so bloody small on the replies...need a magnifying glass to read them.

aha - looks like you found a patent for such a blade.

Other than the Yamaha LU plugs, I haven't been able to google up even a hint that the concept exists

Easy enough to make from a nice big flat head screw driver...if you have a bench grinder.

What do most hate most about flat bladed screw driver bits? They slide out of the damn slot.

Why not a bit to prevent this?

Try the new screw. Assume the dealer is paying for it. If that doesn't work, helicoil as mentioned.

Suggest the postimage for posting pics. Rodbolt can't view the format you used.
He uses an Apple II from 1977.

Ok - just did that Scott. Can RodBolt view them on the post image website
or am I to move them to our forum somehow

+1 ^^. VERY easy to use, free too! Set the image for a 19" monitor...

What do most hate most about flat bladed screw driver bits? They slide out of the damn slot. Can bugger up the screw or worse, adjacent structure. Or allow one to stab oneself in the hand.

Why not a bit to prevent this? So Yamamoto can install screw after screw after screw without buggering up a brand new pristine lower unit.

Yamaha has tools that defy my ability to adequately describe them.

Picture the water pump tube on an F250 with a 30" drive shaft. Lower unit is removed. A tool goes up inside the water pump tube. A drill motor turns the tool. The tube is cut from the inside out by a distance of 5 inches. Another tool then fits over the cut end of the tube. A drill motor turns that tool and rounds the end of the tube so that it will nicely slide into the water pump housing. Voila, the water pump tube is now the length that is needed for a 25" motor.

I totally agree - it is so simple but when a dealer is on the hook he's got to go
through his progression before hitting the end of the trail. I just downloaded
some pix off my I-Phone into my computer. If I can figure out how to get a couple of pix onto this site, you'll understand what led me to surmise that thre is a problem with the plug itself.

Here goes - It says I have uploaded two files.

production tooling on the assy line is a tad different than the tools we use.
while I might do 4 or 5 plugs a day the line may do hundreds.
it is a stupidly simple two flat surfaces with a gasket. one surface is damaged.

[ausnoelm]

I think he means to "vent" the air in the hole the magnet goes into when it is pressed into the plug, as mentioned, it is a pretty simple concept, a nice flat surface, mating to a nice flat machined surface on the plug, with a gasket/washer between them, as long as the plug screws in nice a square, and the two surfaces are OK, it cant leak, so, something is wrong, it was/is cross threaded, stripped, or damaged.
