A Guide to Replacing Your Lower Unit
A Guide to Replacing Your Lower Unit
When disaster strikes, like hitting a submerged object that damages your boat’s lower unit, knowing the steps to take can save time, money, and frustration. This guide walks you through diagnosing damage, understanding your options, and choosing the best replacement for your gearcase lower unit.
Step 1: Assess the Damage
If your boat motor has stopped functioning properly or you suspect internal damage, don’t ignore the issue. While minor damage to gears may not show immediate symptoms, continued use can lead to further wear and eventual failure.
- Thorough Diagnosis: Have your motor inspected by a professional to confirm internal damage.
- Check for Insurance Coverage: Many boat insurance policies cover accidental damage. Contact your provider to understand your coverage and follow their instructions for filing a claim.
Step 2: Choose the Right Replacement Option
When it’s time to replace your lower unit, there are three primary options:
Brand New Manufacturer Unit (OEM)
A brand-new OEM unit is produced by your motor’s manufacturer (e.g., Mercury, Volvo). It features original factory parts and guarantees superior quality and reliability.
- Pros:
- Outstanding quality with precise manufacturing.
- Includes a warranty (varies by manufacturer).
- Ships quickly (usually within 24 hours).
- Cons:
- Higher price compared to other options.
- Best For: Boaters seeking the highest quality and can accommodate the premium cost.
New Aftermarket Lower Unit
Aftermarket lower units are typically made overseas, often in China, and are designed to mimic OEM specifications. While more affordable, their quality control is often inconsistent.
- Pros:
- Significantly lower prices compared to OEM units.
- Some manufacturers offer a 3-year, fault-free warranty.
- Fully compatible with OEM drives.
- Cons:
- Quality control and manufacturing standards can vary.
- Warranty replacements can be time-consuming and inconvenient.
- Best For: Budget-conscious boaters who are willing to take a risk on quality.
Remanufactured Lower Unit
A remanufactured lower unit combines the benefits of OEM-quality parts with a more affordable price. These units are rebuilt by trained mechanics in the U.S. and offer a reliable alternative to brand-new OEM units.
- Pros:
- Priced at deep discounts for significant savings.
- Rebuilt with OEM parts by expert mechanics.
- Typically include a 1-year warranty (varies by provider).
- Ships quickly (usually within 24 hours).
- Cons:
- Warranty periods are shorter than some new aftermarket options.
- Best For: Boaters looking for a balance between quality and affordability.
