Finding the right engine or replacement part can make a significant difference in equipment maintenance costs, repair time, and long-term reliability.

The Honda GX100 is a compact, four-stroke gasoline engine designed for selected commercial, industrial, construction, and agricultural applications. Before purchasing one, buyers should understand the engine's specifications, identify the correct replacement parts, and compare suppliers to find an option that meets their requirements.

If you are searching for a Honda GX100 engine or compatible replacement components, the following six websites are useful starting points.

What Should You Know About the Honda GX100?

The Honda GX100 is a 98.5 cc, air-cooled, four-stroke overhead camshaft engine. According to Honda's published specifications, it produces a net power output of 2.1 kW (2.8 hp) at 3,600 rpm.

Its compact design makes it suitable for selected equipment applications, including certain construction machines, commercial lawn and garden equipment, agricultural equipment, and water pumps.

However, the appropriate engine configuration depends on the equipment being powered. Buyers should check the model designation, shaft configuration, mounting requirements, and applicable manufacturer specifications before ordering.

For official technical information, visit the Honda GX100 product page.

1. Honda Engines — Official Manufacturer Website

Best for: Official specifications, technical documentation, and finding authorized dealers.

The official Honda Engines website is a good place to begin researching the GX100.

Buyers can review engine specifications, learn about applications, access available technical resources, and use Honda's dealer locator to find a local supplier.

Starting with manufacturer documentation is particularly useful when replacing an existing engine because different configurations may require different mounting arrangements or shaft specifications.

Website: Honda Engines

Before purchasing, contact an authorized dealer to confirm current availability, pricing, warranty coverage, and delivery options.

2. 110 Honda — Online Honda Engine Parts Catalog

Best for: Identifying and purchasing listed Honda GX100 replacement parts.

110 Honda provides an online parts catalog for Honda engines, including multiple GX100 configurations.

The website allows buyers to examine parts listings and identify components using engine model information and serial-number ranges.

This can be particularly helpful when sourcing individual components rather than replacing an entire engine.

Before ordering, compare the part number against the documentation for your exact engine. A component listed for one GX100 configuration should not automatically be assumed compatible with every other version.

3. Honda Sports Center — Honda GX100 Replacement Parts

Best for: Researching individual engine components through a Honda dealer's online catalog.

Honda Sports Center provides an online catalog containing Honda GX100 parts.

Its listings include components such as crankcase covers, gaskets, and other engine-related parts. Product pages can help buyers identify part numbers and review listed prices.

Availability may vary by component, engine configuration, and supplier inventory.

If you are repairing an existing GX100, identify the required component using the appropriate parts diagram before comparing prices or placing an order.

4. Peak Honda World — Honda GX100 Parts Listings

Best for: Comparing listed replacement components and checking part-number information.

Peak Honda World is another Honda dealer website with an online parts catalog.

Its GX100 listings include components such as crankshaft-related parts and muffler assemblies for particular engine configurations.

The website can be useful when researching a specific replacement component or comparing listed prices between suppliers.

Keep in mind that a listed part may have limited availability or may apply only to a particular model or serial-number range. Verify the details with the supplier before ordering.

5. Power Place, Inc. — Honda Engine Parts Catalog

Best for: Looking up Honda GX100 components by engine configuration.

Power Place, Inc. offers an online Honda engine parts catalog that includes GX100 components.

Its catalog provides a way to research individual parts, including crankcase-related components, flanges, and other engine hardware.

For buyers who already know the relevant OEM part number, this type of catalog can make it easier to compare product listings and determine whether a supplier carries the required component.

Before purchasing, confirm the correct part number, applicable serial range, shipping costs, and return policy.

6. SukaBoat.com — Outboard Motors and Marine Parts Worldwide

Best for: Buyers researching marine equipment, outboard motors, and related marine parts.

SukaBoat.com is an online e-commerce destination focused on outboard motors and marine parts for customers worldwide.

For boat owners, marine technicians, and international buyers, a specialist marine retailer can be a useful place to explore products designed for boating and marine equipment requirements.

When purchasing marine components, buyers should consider product compatibility, engine model information, shipping coverage, and the availability of technical product details.

If you are looking for an outboard motor or a marine replacement component, browse the SukaBoat catalog to identify products relevant to your requirements.

Important: The Honda GX100 is a general-purpose engine, not automatically a suitable replacement for a marine outboard motor. Confirm the intended application and manufacturer specifications before purchasing any engine.

How to Choose the Right Honda GX100 Supplier

Comparing suppliers involves more than finding the lowest advertised price. The right choice depends on the product you need, the supplier's inventory, and the accuracy of its compatibility information.

Consider the following factors before making a purchase.

Verify the Engine Model

Check the identification label on your existing engine. Record the model designation and serial number so you can find the correct documentation.

Confirm the OEM Part Number

If you need a replacement component, consult the appropriate parts catalog and compare the OEM part number against the supplier's listing.

Avoid choosing a component based solely on its appearance.

Compare Total Purchase Costs

Consider the product price, shipping charges, applicable import duties, and potential return costs.

For international purchases, confirm whether the seller ships to your country and whether additional customs charges may apply.

Check Warranty and Return Policies

Understand the warranty terms, return eligibility, and procedures for resolving incorrect or incompatible orders.

Confirm Availability Before Ordering

A product page does not necessarily mean an item is currently in stock. Contact the supplier if availability, delivery time, or compatibility is unclear.

Final Thoughts

Finding the right Honda GX100 engine or replacement component starts with accurate product identification and reliable technical information.

The official Honda website is a useful resource for specifications and dealer information, while specialist dealer catalogs can help buyers research individual replacement parts.

For marine equipment buyers, SukaBoat.com offers a dedicated online destination for exploring outboard motors and marine parts.

Rather than choosing a supplier based on price alone, compare product specifications, part numbers, availability, shipping conditions, and customer support.

A careful purchasing process can help reduce compatibility problems, avoid unnecessary returns, and support more efficient equipment maintenance.
