I am installing a SE Sport 300 Hydrofoil onto my 135 Mariner Outboard. This comes with four rubber washers that go between the cativation plate and the hydrofoil, one set thick and the other thinner. Do the thicker washers go on the front edge, or the rear of the hydrofoil? The directions faded out and cannot make it out.<br /><br />Thanks,<br /><br />Ruben
