FYI...

The Lowrance gimbal screw fits the Humminbird 997. So now I gots 1 gray screw and one black screw on the 997. Gotta be a hybrid...

Havta buy 2 screws if you order. I only need one. Geez.....I will loose the spare and prob have to order another pair,...continuous gouge loop.......

Keep your gimbal screws, they can cross pollinate.:p

Both screws prob made by kids in the same sweat shop in China.

Keep out of mouth as the knob may have lead in it's paint....

Lowrance and Humminbird needs a dummy rescue bag with spare parts for us old farts.....included at purchase. Don't know why it costs 10 bucks to ship 1 oz worth of screws???

Engineers must be doing the packing. They ain't doing much fixin'.
