I’m getting ready to install the type E on my ‘76. I have everything I need except the highlighted gasket. Parts list shows I need 2? unless I’m seeing it wrong, why would I need two? Also can I just make my own gasket or is it more like a fiber washer?

It's actually a copper sealing washer, and I'm not sure why the parts diagram calls for 2 (a mistake probably?) because you only need one.

Thanks for that clarification 5T but what size is it? Can I use an O-ring?

 

[Jim]

Copper. It only takes the one.

I’m assuming it’s an 18mm?

 

[5twins]

The only measurement I know off hand is that it's about 1mm thick. The O.D. and I.D. shouldn't be hard to figure out though. Looking at Jim's pic, you can see the O.D. is about the same as the round portion of the lock nut. The I.D. will be slightly larger than the screw diameter.

It seems this same sealing washer is used on many Yamaha outboard motors, and they charge much less for it, lol .....

Thanks 5T I ordered the 18mm washers off Amazon for $10 with free shipping so I did ok except I’ll have 30 of them. Anybody need one? lol.

Now that I think about it I am probably getting plated Chinesium washers. Probably send them back and order the right ones.

Worth seeing if they stick to a magnet before deciding to send them back?

They’ll be here tomorrow. We’ll know then.

I've gotten plenty of gen u wine copper washers from CHINA.

Well, I was surprised, passed the magnet test and cut one in half. All copper so I’m ready to go..
