Review MERCURY 9.9hp 4-stroke Outboard Grommet Bushing fits 1997

The **Mercury 9.9hp 4-Stroke Outboard (Models 23-826618, 25-828129, 1997)** is equipped with a **T144 grommet bushing**, a critical component designed to ensure smooth, reliable, and long-lasting performance of the engine s lower unit. This bushing serves as a precision-engineered seal between the propeller shaft and the outboard s housing, preventing water ingress while reducing friction and wear on the drive components. Crafted from high-grade **nitrile or EPDM rubber**, depending on the specific application, the T144 grommet is engineered to withstand the harsh conditions of marine environments, including exposure to saltwater, UV radiation, and constant mechanical stress from propeller movement. Its tapered design allows for an optimal fit, ensuring minimal play while maintaining flexibility to absorb minor misalignments, thereby protecting the internal shaft seals and reducing the risk of premature failure in the outboard s lower unit. Over time, these bushings can degrade due to age, chemical exposure, or physical wear, leading to leaks, vibration, or even complete seal failure making replacement a crucial maintenance step for preserving the engine s efficiency and longevity. Whether used in recreational fishing boats, small watercraft, or utility vessels, the T144 grommet plays a vital role in maintaining the integrity of the Mercury 9.9hp s lower unit, ensuring quiet operation, reduced drag, and extended service life between major overhauls. Proper installation, using the correct lubricant and alignment techniques, is essential to maximize its performance and prevent premature wear on adjacent components.

### **Pros and Cons of Buying a Mercury 23-826618 (25-828129) 1997 9.9HP 4-Stroke Outboard with Grommet Bushing (T144)**

1. **Affordability** Older Mercury 9.9HP outboards are generally inexpensive compared to newer models, making them a budget-friendly option for small boats, canoes, or kayaks.

2. **Lightweight and Portable** The small size and low horsepower make it easy to handle, transport, and store, especially for recreational use on small watercraft.

3. **Fuel Efficiency** 9.9HP engines consume very little fuel, reducing operating costs for short trips.

4. **Simple Maintenance** Being a basic 4-stroke outboard, repairs and upkeep are straightforward compared to larger or more complex engines.

5. **Compatibility** Fits well on small boats, canoes, or kayaks where power isn t a primary concern.

6. **Potential for Restoration** If you re mechanically inclined, restoring or upgrading it could be a rewarding project.

7. **Low Environmental Impact** Lower emissions compared to larger engines, making it a better choice for eco-conscious users.

1. **Age and Wear** A 1997 model is nearly 30 years old, meaning parts may be outdated or harder to find, and the engine could be worn out.

2. **Reliability Issues** Older 4-stroke outboards from this era may suffer from common problems like fuel system clogs, worn gaskets, or electrical failures.

3. **Limited Power** The 9.9HP rating is extremely weak for most practical uses beyond very small boats or trolling. It struggles with waves, wind, or any significant load.

4. **Fuel and Emissions Regulations** Some areas may have restrictions on older engines due to emissions standards, though 9.9HP models are often exempt.

5. **Part Replacement Challenges** Finding original or compatible parts (especially for the grommet bushing or other worn components) can be difficult.

6. **No Modern Features** Lacks electronic diagnostics, fuel injection upgrades, or modern efficiency improvements found in newer models.

7. **Potential for Hidden Damage** Without a thorough inspection, you may inherit rust, corrosion, or internal engine issues that require costly repairs.

The Mercury 9.9HP 1997 model is a viable purchase if you need a **very low-cost, lightweight, and simple** outboard for **small, calm-water applications** (e.g., a canoe, kayak, or tiny boat in a sheltered lake or slow-moving river). However, if you expect **any real performance, durability, or long-term reliability**, this engine is likely not worth the investment. The **grommet bushing issue (T144)** suggests the engine may already have internal wear, and without a full inspection or service history, you risk buying a problem.

- You have a **very small boat** and need minimal power.

- You re **mechanically skilled** and willing to restore or replace parts.

- You re using it **occasionally** in **calm conditions** and don t mind limited speed.

- You find it at a **very low price** (under $100) and inspect it thoroughly for leaks, corrosion, or mechanical issues.

- You need **any real speed, reliability, or modern performance**.

- You plan to use it **regularly or in rough water**.

- You cannot afford **potential repairs or part replacements**.

- You want a **long-term investment** consider a **used but well-maintained 4-stroke from the last 10-15 years** instead.

For most practical purposes, a **new or lightly used 5-10HP outboard** (even from a different brand) would be a far better choice for balance between cost and functionality. If you re set on this engine, **inspect it thoroughly, test-run it, and budget for repairs** before purchasing.
