Recommended Configuration for Top Performance: Our modified engines will achieve top performance with our pipe systems. Specifically, the BZx4 Ultra Modified Zenoah G260PUM will achieve maximum performance with the BONZÍ Race Performance Pipe. At a minimum, a quality, dry, race type (tuned) pipe is essential for all modified engines. Optimum performance will also be affected by your header pipe. For example, the BONZÍ BZx4 modified Zenoah requires a much shorter pipe than a stock Zenoah engine. Be sure to follow the manufacturer’s recommended lengths for tuning for your particular pipe configuration. If you have questions, do not hesitate to ask.

Many factors will affect the performance of a modified engine. These include (but are not limited to): hull weight and type (cat, v bottom, hydro, outrigger, etc.), propellers, altitude, humidity, whether it is being run in salt or fresh water, as well your individual setup. Contact us via e-mail with any questions.

For a great deal, try the BONZÍ Power Packagewhich includes a Zenoah engine, Mounts, Collet, Clutch, Water Pump and choice of the Quiet Power Tuned Pipe or Performance Race Pipe Systems. Or opt for the package without Clutch & Water Pump if you prefer!
