In this way, how do you manually lift a Mercruiser outdrive?

In this way, how do you manually lift a Mercruiser outdrive?
Hand the other end of the rope to the person on board. Grasp the bottom of the outdrive behind the propeller. Pull the outdrive up and hold it until the person on deck ties the rope onto a cleat, completing the manual raising of the Mercruiser outdrive.
When that happens, the motor will usually tilt all the way down and will not go up or will stick. Hydraulic fluid doesn't evaporate, so if you can hear the trim motor running but your outboard won't tilt up, you likely have a leak. here
How do you bleed a Mercury trim?

Those fins are real tricky to straighten. Real easy to bend em too far or too many times and they like to break because of them being poor quality cast aluminum.

I find that if the best blade is traced onto paper, then cut out, it makes a good "gauge" to hold up to damaged blades to identify the bad spots, or to make them all even.

Tilt is the mechanism that allows the outboard motor to tip radically forward far enough to raise the part of the motor below the actual engine (called the lower unit) as well as the propeller to the surface or completely out of the water. Tilting the motor up and down is usually done with the motor turned off or in neutral. Trim is the mechanism that moves the motor over a minor range from fully down to a few degrees upward. On hydraulic models, trim is usually activated while the motor is running and in gear. here
All outboard motors are hinged to allow varying the angle of attachment of the mostly vertical alignment of the motor, drive train and propeller in relationship to the mostly horizontal plane of the stern of the boat to which the outboard is attached. This adjustment can be manual or mechanical. Most large outboards above 100 horsepower feature electrically actuated hydraulic tilt and trim, most small outboard motors of 40 hp and below have manual T&T. In-between, the standard is manual, but hydraulic systems are an available option.
To work properly, the lower unit and propeller of a boat needs to extend into the water deeper than the bottom of the hull of the boat. In extremely shallow water or when launching or loading a boat on or off a trailer, the lower unit of an outboard in the tilted-down position could drag on the bottom of the lake or boat ramp. Once on the trailer, an outboard in the tilted-down position could allow the lower unit to hit or drag on the road.
Occasionally, a motor’s propeller will foul with weeds, ropes or fishing line. Tilting the motor into the fully up position facilitates removal of whatever is caught in the prop so the boat can get back underway. [links]
When boat powers up from standing still to high speed thrust of the propeller suspended below the bottom of the boat causes the stern of the boat to push down into the lake. Trimming the motor to the extreme “down” position directs the thrust of the propeller upward to a small extent as well as forward, thus lifting the stern as the boat gains speed. The result is faster acceleration. Once the boat is up on plane, meaning it’s skimming across the water’s surface instead of pushing through the water, a motor trimmed completely down tends to push the bow of the boat down, now slowing the boat. To compensate, the helmsman can trim the motor up gradually until the boat rides fast and level. On a manually trimmed boat, the motor can’t be trimmed while underway. The boater needs to experiment with various trim settings to determine which gives the best combination of acceleration and high speed operation.

I just had this problem on my 1996 175 HP with the triple ram style trim system. - trim motor still runs with both up and down buttons, but motor wont move. - I am familiar with the old style merc trims with the hydraulics inboard, amd hoses out to the cylinders on each side of the motor, but this unit looks like the motor is outboard at back under the engine?? Where would I find a manual relase on this puppy to try out ? [links]
It's a 75 model bass boat, don't know what type unit it would be or where the manual release is. Can you elaborate please. Thanks
i have the same problem but mine is a 80 hp merc it worked once now it is stuck can hear solinoid trying but won't budge where is manual release and the pump can u please elaborate more on how to manually get it down or up any help will be appreciated more
