We are proud to introduce you to the
NEW RSRacecraft Hydro-Blaster 2.0. The design team took our tried, tested and proven Hydro-Blaster and went to work on trying to improve it for 2021. With the fast evolving mini jet boat industry we felt it was important to re-evaluate our super successful Hydro-Blaster and give it a few tweaks to help maintain optimum performance.
Here are the changes:
Raised Intake height:
The reason for this was with the bigger 4 stroke PWC engines oil plan clearance was becoming tighter and tighter. With adding UHMW the nuts would would protrude into the engine compartment under the oil pan and with heavy rock strikes we found that the nuts were getting a little close to the oil pan. By increasing the height of the intake it instantly rectified this problem.
Rear Steel Wedge:
For 2021 the Hydro-Blaster now comes with more durable steel wedge.
Stomp Grate Compatible:
Our New 2.0 Hydro-Blaster now comes with a stomp grate option, all 2.0 Hydro-Blasters are compatible so if you wanted to upgrade at a later date this is also an option. Having spent 2 years testing and developing we have finally developed a stomp grate that doesn’t hinder intake performance. Having tested other stomp grates we found that the flex in the intake bars caused by the stomp grate would cause disturbance in the water flow into the impeller thus causing unwanted cavitation. We ensured when building ours that the tolerances were extremely tight for the stomp bars, this solved the problem of the bars flexing and eliminated cavitation.

In a very short time mini jet boats have evolved a great deal…. What started as a grass roots effort in home workshops using wrecking yard jet ski parts has now turned into a purpose built industry capable of extremely high performance. What began with 60-90 hp repurposed jet ski drives in now 100-500hp boats reaching speeds well over 70mph.
The simple sheet metal inlet ducting that was adequate with low horse power projects of the past is no longer a realistic option in the current high- performance mini jet boat applications.
When the team at RSRacecraft began to transition from 30 years of building world championship level PWC to developing high performance mini jet boats we saw an opportunity we needed to apply our years of jet pump development to building the ultimate mini jet boat intake. We committed over 9 months of development to the design of the Hydro Blaster. Calling upon our experience both on the water and in the workshop using the latest CAD software, rapid prototype technology, as well as our in-house CNC facility. The goal of the project was to optimize the Hydro Blaster performance by: • Shallow Water Capability • Rocky and Abrasive Environments • Ballistic Acceleration • Top Speed • Rough Water Hookup Previously Not Available to Mini Boat Builders
Due to the low inlet floor and velocity friendly shape of the Hydro Blaster a level of performance never before possible are easily achieved with PWC base jet pumps while still using a well designed intake grate to keep large stones and debris out.
STOMP ACTUATOR KIT
This kit ONLY works with our Hydro Blaster Stomp Grate in WattsCraft Boats. You may be able to use it in other applications but we do not support other uses or have technical support if you choose to do so.
* Each Hydro-Blaster is machined to order to fit your model of PWC donor. Depending on your donor and current inventory lead time on shipping is approximately 2 weeks. For more information on lead times and inventory please call or e-mail sales@rsracecraft.com
