Motor goes down all the way, but this only gives me a neutral trim (90 deg to water surface). I need some negative trim. I opened the valve on the PTT unit and the motor dropped to where I want it to drop to. I closed the valve on the PTT. As soon as I raised it and then try to lower it again, the relay clicks the movement off right to where it's original limit was. The manual instructs on how to adjust the upper limit, but not the lower limit. How do I do this? My boat is getting a ridiculous amount of bow rise before planing out and I'd like to try solving this with negative trim vs. drilling for a hydrofoil if I can avoid it. For reference, it's a 14' Twin Vee with a 60hp motor. It's got a 12 pitch stainless prop which hits 5750 RPMs, so power is not an issue.
