16HP JONO & JOHNO VERTICAL SHAFT ENGINE
Top of the range, 16HP vertical shaft engine. 2 year warranty.
Equal to any brand name engine on the market today.
There are a few things you need to check before purchasing any vertical-shaft engine to ensure it fits your mower.
Bolt Pattern: Our engine has a Briggs & Stratton bolt pattern. You can view a schematic of the bolt pattern in our thumbnail pictures. If you have a Briggs engine then the bolt pattern will be a perfect match. Bolt size: M10 x 1.5 (bolts not included).
Output Shaft Size: The output shaft on our engine is 1” (25.4mm). Almost all ride-on-mower engines with a HP rating between 9hp and 18hp will have 1” shafts. The thread pitch for the output shaft is 7/16 20 UNF -2B.
Physical Size of Engine: If your mower has only a limited amount of space for the engine to fit into then you will need to check the physical dimensions of our engine before purchasing. A schematic of the engine’s physical dimensions can be found in the thumbnail pictures of our listing.
PLEASE NOTE: THIS IS AN UNIVERSAL FITMENT ENGINE AND SOME MODIFICATIONS TO THE MOWER MIGHT BE NEEDED, INCLUDING (BUT NOT LIMITED TO) THE MUFFLER AND EXHAUST SYSTEM.
FEATURES:
- Optimized balance system, vibration reduction and more stable operation.
- Overhead valve (OHV) design and lower engine temperature
- Secondary oil filtration system enables better lubrication of engine, reduces wear and prolongs engine life
- Cast iron casing does not only effectively improve lubrication, but also makes engine more resistant to wear and prolongs engine life

Please note:
Two of the mounting holes require thread tapping to suit your application.
