Trolling plate

[chowder]

I cant seem to figure out how to really lock my Cabelas pro-troll plate into the down position. The latch/shear pin goes into the plate, but just at idle my 40 hp Merc 4 stoke pops it up. It seems like I need to put a wedge or a screw driver into the gap to keep it from popping out- anybody have a suggestion?

I can't help you with that plate, but, I used this one http://www.cabelas.com/prod-1/0000915012282a.shtml on my Merc 50 4s, and I couldn't be happier. It gets me down to about .5 mph GPS without any loss of top speed. My son thinks it has a bit more top end, and well, kids KNOW top end.
