VF250 4.2 V6 SHO – 450s Supercharger Kit
Look what’s cooking!!
Activate “Beast Mode” on your rig with this easy recipe:
- Add 1 * Nizpro 450s ECU Flash
- Add 1 * Nizpro 450s Supercharger kit
- Get your boat to the water and prepare to have your mind blown… (now that your engine is also!!)
Described in a boat test article as both spellbinding and brilliant, the Nizpro 450s Yamaha V6 will give you the incredible confidence in your rig. With its quiet brutal performance, powerful acceleration and improved fuel efficiency at normal cruising speeds, you need to think of it as having the torque of a diesel and the responsiveness of a petrol engine, and it all weighs in at over 150kg lighter than Yamaha’s 425hp petrol V8.
A Nizpro 450s Supercharged engine is ideally suited to use in boats looking for range, ability to haul decent mass, and ease of operation for prolonged periods of time. It delivers real world punch at suitable revs and will drink only as it needs, which is pretty miserly considering the performance you get. It is also quieter, by virtue of not having to work anywhere near as hard to get you where you want to go.
What about Value for Money?
Compared to running twin 250hp Yamaha six-cylinder outboards, the Nizpro Marine Supercharged 450s Yamaha is over 200kg lighter with no additional drag through water and no additional ongoing 2nd motor service costs!
Easy to install in under 4 hours, your Nizpro 450s kit comes complete with comprehensive instructions where no additional parts or fabrication are required. Do it yourself OR have your marine technician do it for you!
Please note that all NIZPRO ECU Flashing Software is ONLY compatible with Windows Computers.
