I have a thought/question/ concern. So I'm using cheaper hardware with the 3mm nylon rudder breakaway screw. At 95 plus mph speeds should I be concerned with that screw breaking at that speed? I noticed after I'm done running it, the rudder is tilted back against it. It flipped once and when I brought it in, the screw was broke. In my mind it the screw broke, it would potentially cause a flip because the drag of the rudder helps bring the bow down...right? So lose this down force and front comes up...flipping starts....am I on to something? Was going to use a brass screw...bad idea?

Yes, i have had to ditch the break-away screws on some of my boats because the tiled back rudder changes my set up and sends the bow down during a turn and causes one of the sponsons'steps to trip on the water. IMO, between hitting a branch or a turtle and having a nasty flip, I rather chance the rudder... lol...Too many boats, not enough time...

Alright. I picked up some brass screws. I could care less about messing up a rudder, I didn't want to worry about knocking the transom off lol32" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) wasComment

Actually if we could dig up some aluminum screws they would be perfect for this. I have broke many nylon ones due to speed and the sliding breakaway rudders...
I might add that I have ripped open transom a with brass screws.Comment

This post makes me nervous. The good thing is it made me think a little more about this. Part of my problem is the slack it has with the factory hole and 3mm screw. They drilled it a touch too big. Then I remembered I bought a bag Of 6-32 nylon socket head screws. They are bigger than the 3mm screws and I can fix the slack problem by drilling a tighter hole.32" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) wasComment

One problem with all break-away rudders is the lack of friction between the rudder and the bracket. You will find that if you rough up the part of the rudder which is clamped in the bracket with 100 grit paper, and do the same for the inside of the bracket, your rudder's unwanted movement at high speeds will be greatly reduced or eliminated - shear pin or no shear pin.

I was using nylon and Doug Sick showed me how he uses brass tubing that is a snug fit in the hole and then just crimping the end down so it can't pull out.Namba District 16
