Honda Engines Dealer in Central New York

Honda Engines builds GX, V-twin, iGX, GC and electric eGX engines for mowers, pressure washers, pumps, generators and construction equipment. Clinton Tractor in Clinton, NY is a Honda Engines dealer, and Honda's parts catalog looks up parts by engine serial number.

Mini 4-stroke engines

The GX25, GX35 and GX50 Mini 4-Strokes can be used and stored in any position, the maker says. The GXH50 and GXV50 are 49.4 cc commercial engines for horizontal and vertical applications.

GX and V-twin commercial engines

Honda's GX and V-twin series are its commercial engines, listed for water pumps, tillers, generators, pressure washers, mowers and construction, forestry and agricultural equipment. Single-cylinder GX engines run from 98.5 cc to 389 cc, and the V-twins are 688 cc.

iGX engines

iGX engines add an integrated electronic control unit with a self-tuning regulator governor. The larger V-twin iGX models add electronic fuel injection and drive-by-wire control.

GC, GCV and GS residential engines

GC, GCV and GS engines for residential mowers and pressure washers, with the GS models listed by Honda for light commercial and residential use. The GC and GS models use an internal timing belt that Honda says is designed to last the lifetime of the engine.

eGX electric power units

The Honda eGX is a battery-powered motor for OEM equipment. Honda says it is meant to match the output of a GX100 or GX120, mounts like existing GX models, and suits indoor work and noise-restricted sites.

GX warranty

Honda says GX engines of 100 cc and larger carry a three-year commercial warranty.

Warranty terms

Honda's warranty page says the warranty applies to all Honda GX engines, 100cc or larger, purchased at retail or put into rental service since January 1, 2009. It excludes the Honda GXV160 model.

Emission control system warranty statements are posted by emission label year on the Honda Engines warranty page. Read the full terms there before relying on coverage.

Fuel limit

Honda engines are designed for gasoline with 0 to 10% ethanol, and Honda says not to use more than 10%.

Fuel recommendation

Honda says its engines are certified and designed for regular unleaded gasoline, and are not certified to run on E85 or other alternative fuels.

Honda also says to follow the storage guidelines in your owner's manual if the engine will sit more than 30 days.

Options

Honda lists these options on its engine pages. Which ones fit depends on the engine model, so check the model page or ask about your application.
