ahh i now see the issue you all are talking about..i just went and looked at plate and i thought it was hinged but looking under the boat ,its all one piece..
i guess i can just the whole bennets 12 inch trim tab kit with plate and install it in place of the existing plate...??
More work but still i like the plates on the newer supras,they work great for planing quick and then dropping the hull all the way back down and lets the weight sink the boat when all in the full up position..
