I have a '72 merc 1400. I finally got my electrical worked out on my trim. I can hear the motor buzzing when i switch up and down, but the motor does nothing. I unhooked the hydro lines to swap it for another unit. I bled the lines till the fresh oil came out. My question is i have 4 hydro lines on the bottom, 2 big, 2 small. Is it possible that i hooked the hydro lines up backwards?
