When a trim/tilt unit fails, your outboard can feel like it's stuck in the wrong position, and getting back to normal usually means a full assembly swap. The Power Trim Tilt Assembly 8M0055011 830250T3 is positioned as a replacement for Mercury and Mariner outboards in the 35HP to 60HP range, including EFI and Sea Pro variants. If you're in the middle of that horsepower bracket and want a single part to restore tilt function, this is the one to evaluate.
Quick Verdict
For boat owners running a Mercury or Mariner 35-60 HP outboard with a matching serial range, this assembly at USD 467.10 offers a complete trim/tilt unit in new condition. It includes the 8M0055011 / 830250T3 part references and is described to replace multiple OEM numbers, so it covers a fairly wide retrofit window. The main thing to confirm before buying is that your motor falls into the listed 35HP, 40HP, 50HP, or 60HP family and matches the "1C453840 & Up" or "7E60452IZ" serial references.
Who It Suits
This makes the most sense if you already know your outboard's horsepower and serial range and you're ready to handle the replacement work yourself. It also suits owners of Mercury or Mariner 60HP EFI models from 2007, since the description specifically calls out that application. If your motor is outside the listed horsepower or serial brackets, you'd need to source a different unit.
What Stands Out
The biggest draw is the all-in-one format: you're getting a power trim tilt assembly, not just a hydraulic cylinder or a pump. Weighing 11.6 lb and measuring roughly 15 x 7.7 x 5.5 inches, it's a compact, manageable package. The compatibility list is also specific-Mercury 50HP, 50HP EFI from serial 1C453840 & Up, plus 35HP, 40HP, 60HP, and Mariner 60HP 7E60452IZ 2007-so you can cross-check your own serial number against the unit before committing.
Trade-Offs to Consider
Fitment hinges on your specific motor's serial number rather than a simple year/model match, so you'll need to verify that before ordering. The listing also includes a request for your vehicle VIN to confirm suitability, which may feel out of place for a marine part. Be ready to provide your outboard's serial number and, ideally, confirm the original trim/tilt part number before purchase.
Power Trim Tilt Assembly 8M0055011 830250T3 Replacement for Mercury Mariner 35HP
For Mercury and Mariner owners in the 35-60 HP bracket, this new assembly brings the core trim/tilt function back in one package. The strongest reason to choose it is the wide application list: 35HP Jet, 40HP, 40HP EFI Sea Pro, 50HP/50HP EFI, 60HP/60HP EFI, and the 2007 Mariner 60HP at serial 7E60452IZ. The limitation is that fitment isn't universal-you need to match your motor's serial range to the "1C453840 & Up" or the Mariner-specific number, and if your outboard doesn't sit in that list, this isn't the part for you. At USD 467.10, it's a complete assembly option priced straightforwardly for what it offers.
Bottom Line
If your Mercury or Mariner 35-60 HP outboard matches the serial ranges in the product description, the Power Trim Tilt Assembly 8M0055011 830250T3 is a direct way to get a new trim/tilt unit without tracking down multiple OEM parts. Confirm the serial range first, then use the price and dimensions to plan your install.
