Performance & Practical Benefits

A trim and tilt motor might seem like a small part in a big system, but you feel its importance the second it hesitates — or worse, fails. The 8M0031551 delivers smooth, confident movement every time you bump the switch. The motor responds with a quiet, steady push that feels solid and controlled, letting you fine-tune your running angle whether the water is flat or rolling with chop.

You’ll notice how tight the system feels when raising the engine to trailer height or easing it down before launching. That smooth, predictable motion protects the ram, prevents jerky transitions, and keeps your engine exactly where you want it under load. The durable construction means fewer worries about corrosion, moisture intrusion, or sudden sluggish behavior as the season goes on. It simply works — and when you’re miles from the dock, that reliability is worth its weight in peace of mind.

Why Buy OEM

There’s no guesswork with an original Mercury Marine part. The sizing, power output, and electrical connections all match your system exactly, which means no awkward retrofitting or trial-and-error installs. An OEM trim and tilt motor is built to survive long days on the water, heavy cycles, and constant exposure to heat and spray. It lasts longer, requires less maintenance, and protects the components around it — saving you time and money in the long run. If you’re looking for the option that simply works the first time, this is it.
