Hello! Newbie Here... I just picked up a bass boat from an old bass-pro's estate. It is a 1978 Monark McFast with aJohnson 115 outboard, I have a problem with the tilt/trim system. It tilts up, not down. Tilt motor runs but no real movement down, and the tilt motor sounds strained trying to go down. Works great up. I can use the pressure release screw and it will go down but only to the Trim rods, and they do not move either powered or using release screw with downward pressure on engine. I can not get the engine to drop the trim cylinders at all. I have filled the reservoir and cycled it up/down multiple times to bleed unit. Does anybody have any ideas?
From viewed from the back the Tilt/Trim unit has motor on left, reservoir on the right the tilt cylinder in the middle and on each side of the lift cylinder is a trim cylinder(2 total) the Model number of the Trim unit on the outside of the mounting bracket is 115etL78c and the serial number is j4980804.
Any help would be appreciated.
Thanks,
MP
