I know the trim system and motor pretty well. I agree if the motor has compression the rest can be done to make the motor 100% on the cheap. The old inline 4 50hp is about as tough as a cut nail. The trim pump inside the boat looks factory. It is the same pump that the I/O's use. The hydraulic cylinders are mounted outboard of the clamp bracket. If you start to tinker with the hydraulic hoses be real careful threading the stainless fitting back into the aluminum housing. The three buttons were the same as most all the Merc controls. Down, Trim and Tilt as I recall. With that setup you only need a up and down type switch. The trim pump motor has a brush card and is easy to refurbish if the windings are still good. Had one on the back of a flatbottom boat. Not a ball of fire in the hp dept. but it would absolutely scream and was silky smooth. The good ole' days
