hi guys, i'm new to the forum here so please bear with me . i have a 1972 chrysler 18 foot bow rider with a volvo AQ170B and penta drive 270T. i got a leak in the power trim . i have the seloc manual but it only shows the screw type system. mine is a cylinder on top of the drive inside the engine compartment. i know it's leaking from the seal on the shaft but i am unsure how to remove the yoke or do i have to take the cap off the ram cylinder and unbolt the shaft to remove it? is there any one who knows how or where i can get some info on the web to figure out how to get cylinder out.
