Mercury – 12 Volt Trim and Tilt Motor for OMC | Power Trim and Tilt Series | Marine Grade Construction | 8M6007538

Overview

If you have spent any time running older OMC powered boats, you know how much you depend on that trim and tilt switch. You bump the button, watch the bow rise or settle, and you can feel when the boat is locked into the right attitude. When the motor responds instantly, it makes everything feel easier and more controlled. That is what this Mercury Marine part brings back to an aging system—sharp response, smooth movement, and a little extra confidence when the water is not playing nice.

With part number 8M6007538 on the transom, you are not wondering if the tilt will stall halfway or chatter on the way up. You tap the switch, the motor hums with a steady tone, and the engine glides to where you need it. It is one of those upgrades that quietly makes the whole boat feel younger.

Performance & Practical Benefits

On the water, you feel this motor every time you trim for the conditions. The movement is smooth and steady instead of jerky or hesitant. As you bump the switch, the engine rises or lowers at a comfortable pace, letting you fine tune the ride for chop, following seas, or a smooth afternoon cruise. That tight, even sound from the motor tells you the internal bushings and armature are working the way they should.

Over the season, that reliability shows up in less strain on the hydraulic system and fewer awkward moments trying to dock with a half responsive trim. The epoxy protected armature and copper bushings help this unit shrug off heat, moisture, and constant use in a marine environment. It is the kind of part you install once, bleed the system properly, and then simply rely on. You will notice how much easier it is to dial in the perfect running angle when the trim and tilt respond exactly when you ask.

Why Buy OEM

When it comes to trim and tilt, guessing with a generic motor can turn into a long season of chasing leaks, odd noises, and uneven movement. A genuine Mercury Marine part like this is built to original equipment specifications for output, mounting, and electrical draw. It is designed to match the hydraulic pump and actuator that are already on your boat, so everything works together instead of fighting itself.

In real life, that means fewer surprises at the ramp and a lot less time wrestling with parts that “almost fit.” If a friend told me their older OMC rig was getting slow or weak on trim, I would point them straight to a correct original equipment style motor and to this part number 8M6007538 when it matches their application. It is the practical, long term choice when you want your boat to respond right the first time.
