There are a few things you need to be aware before purchasing any vertical shaft engine to ensure it fits your mower.
- Bolt Pattern
Our engine has Briggs & Stratton, or Honda bolt pattern. You can see refer to the images in the description for the schematic of the bolt pattern. If you have a B&S or Honda engine, the bolt pattern will be a perfect match. The bolt holes on the engine will require thread tapping. - Output Shaft Size
The output shaft on our engine is 1” (25.4mm). Most ride on mower engines with HP ratings between 10 to 18 hp have 1” shafts. But please make sure this is the same for your mower. - Engine Displacement
The displacement of the new engine shall not be less than your current engine to avoid any underpower issue. - Physical Size
If your mower has only limited space for the engine to fit into, you will need to check the physical dimensions of our engine carefully before purchasing. An illustration of the physical dimensions can be found in the images in the description.
Please note this is a universal fitment engine and some modifications to the engine or mower might be needed, including but not limit to the muffler, exhaust system and/or electrical wiring. If you are not familiar or confident to do so, please consult small engine mechanic before purchasing, installing and using.
