The BZx4 Ultra Mod infuses your boat with rocket-speed without sacrificing reliability.
Recommended Configuration for Top Performance: Our modified engines will achieve top performance with our pipe systems. Specifically, the BZx4 will achieve maximum performance with the Bonzi’ 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, a BZx4 requires a much shorter pipe than a stock engine. Be sure to follow the manufacturer’s recommended lengths for tuning for your particular pipe configuration. Many factors will affect the performance of a modified engine. These include: hull weight, hull type, propellers, altitude, humidity, salt or fresh water and your individual setup.

At BONZÍ Sports, we have a wide variety of engines and modifications to help you be the very best, and definitely the most stylish. We offer three Zenoah engines: the G230RC air-cooled, the G260PUM water-cooled and the BONZÍ I2 inline engine. These engines are known for their reliability and ease of use. You don’t want to constantly adjust/fiddle with your engine, now do you? That’s sure to suck out the fun r/c boats have! In case the water-cooled stock engines aren’t quite enough for you, we offer three original BONZÍ modifications: our BZ1 Mild Mod, our BZx2 Race Mod and our attention-grabbing, super-powerful BZx4 Ultra Mod. Each step up in modification adds on average an extra 5MPH to the already powerful stock Zenoah water-cooled engine (pushes a 50-54” boat around 40MPH). To help make the most stylish boats, we have anodized hardware to help you out. We offer a brilliant rainbow of colors: red, orange, lime green, blue, purple, black and silver. There is a color to suit most everyone’s most particular of tastes. We also offer matching BONZÍ Mounts and clutch to complete the stylish look inside your boat, along with matching antenna mounts, water pickups, water outlets and a BONZÍ CZ Out-Drive to continue the style outside. There’s much more to being stylish than strictly custom paint and graphics!
