Benelli B3S Review

The history of Benelli jet skis started in 2006 when the Italian manufacturer acquired the successful Hydrospace. The latter was the boutique European jet ski manufacturer producing the race-intended Hydrospace S4.

After the acquisition, these skis were rebranded to HSR-Benelli, but they were offered in unchanged form.

The all-new Benelli PWC lineup was introduced in 2008, featuring a new runabout model, the Series-R, and a new stand-up labeled Series-S.

Unfortunately, these new Benelli skis didn’t really become popular due to reliability issues and limited availability.

In 2012 Benelli decided to rebrand its fleet again when the Series-S stand-up was renamed the Benelli B3S.

Let’s now get down to the nitty-gritty and talk about these machines in detail!

Benelli B3S Features and Dimensions

The Benelli B3S was available in two configurations, the turbocharged B3S Extreme and the naturally-aspirated B3S Dynamic. These skis shared all the same features except for engine power and color schemes.

The platform of the Benelli B3S was designed from scratch and was made of CMHPCTM (Compression Molded High-Performance Composite).

This hull featured built-in front sponsors and a sharp-contoured aft for the best high-speed stability and cornering. The large hood also ensured easy access to key engine features like the dipstick, oil filter, plugs, and the e-box.

Regarding dimensions, the ski measured 96.46 inches in length, 28.74 inches in width, and 26.38 inches in height, while its dry weight was 439 pounds.

The Ergal handlebar had co-molded grips and was mounted on a lightweight aluminum handlepole. For safety reasons, there was also a soft pad placed on top of the handlepole.

Standard features included a 4.5-gallon fuel tank, aluminum scoop grate and ride plate, easy-release fuel cap, safety lanyard, integrated rub rails, drain plug, and a factory bailer.

Benelli B3S Engine

There’s no question that the most exciting part of this ski was its outstanding 4-stroke engine.

This 1602cc, 3-cylinder DOHC I3C16 Benelli Marine engine featured a dry-sump oil system, multi-point fuel injection system, digital ignition, open-loop cooling, and a water-cooled single-stage downpipe exhaust system.


This triple power source was available in two configurations, the Benelli B3S Dynamic had a naturally-aspirated version that was rated at 135 HP, while the turbocharged Benelli B3S Extreme cranked out 180 HP out of the box.

Thanks to this extreme engine power, the latter hit a 62-65 mph top speed under ideal conditions. This speed was amazing, especially on such a tiny stand-up ski!

What’s more, the B3S Extreme offered an unmatched aggressive sounding exhaust.

Engine power was delivered to the single-stage axial-flow jet pump via a direct drive shaft.

This pump featured an aluminum HPDC housing and a stainless steel sleeve to avoid cavitation, and a stainless-steel, 3-blade impeller.

Benelli B3S Problems

To the regret of many stand-up PWC enthusiasts, the Benelli B3S models never became commercially successful.

As reported by The Watercraft Journal, the hull of these skis suffered from manufacturing issues, which often resulted in hull failures. Because of this, the official release was delayed several times.

When the skis finally hit dealerships, buyers had to face limited availability, as these machines were only marketed in certain parts of Europe, Australia, and New Zealand.

They were never sold in the U.S. as they didn’t meet the strict requirements of the U.S.C.G. Since the company missed out on this huge market, future opportunities were severely limited.

Since only a couple of Benelli B3S were sold, the company eventually dropped its stand-up line in 2016 and rebranded its runabout ski (again) to Belassi Burrasca.
