I just bought a 2000 115 hp evinrude. The engine works great but the second time I put my boat in the water, the Tilt/trim would only lower the engine, and it would not let me raise it. My friend (A marine electrician) tested all the wiring. We even reversed the polarity to see if the hydraulic motor has a burnt coil. It worked in both up and down when we tested it. We checked all the fuses and relays (bench tested the relays) they all seem to work. The entire test we did seem to pass except the raise is not working. Could someone tell me what is wrong? Also when you push the raise button on both the engine and the throttle leaver you have the voltage but you don?t even get a sound from the relays or anything. Please help. Leroy
