Mercury Marine’s New

Quicksilver Thunderbolt

Propellers

Mercury Marine introduced the

Quicksilver Thunderbolt line of propellers for Volvo Penta

Duoprop drives (DPS). The

Quicksilver Thunderbolt is made in the U.S. at Mercury Propellers investment casting foundry in

Fond du Lac, Wis. Performance gains are driven by the

Thunderbolt’s cutting edge four- blade front propellers coupled with a three-blade rear propeller. “For this system, we made the front propeller a four-blade for superior holding and acceleration,” said Dirk Bjornstad, brand manag- er for Mercury Propellers. “As it turns out, the system is also faster on the top end as well.”

The Quicksilver Thunderbolt is available in seven options from a 19 to 28 pitch. It also features

Mercury Marine’s proprietary pro- peller alloys providing superior strength while offering the corro- sion resistance required to stand up to freshwater and saltwater appli- cations. www.mercurymarine.com

Volvo Penta offers comprehensive range of SOLAS approved engines (M.E.D. and US Coast Guard) for fast life and rescue boats. The range comprises three base engines, with no less than 14 output options from 110 to 435 hp, all of which are in-line diesels with common rail and the lat- est in electronic management for sterndrive, inboard and water jet propulsion. The SOLAS range con- sists of the D3, D4 and D6 engines, all featuring the very latest in tech- nology with common rail, 4-valves per cylinder and supercharging with aftercooler. The SOLAS engines are based on standard engine design with a SOLAS kit mounted and tested in factory before delivery to boat builders. The kit includes a shut off valve for crank case ventilation and a tilt switch, to be mounted on the engine room bulkhead.

The new D3 is the smallest in the range with an in-line 5-cylinder arrangement, 2.4 liter displacement and very low weight – only 260 kg bobtail. It is also equipped with a variable diameter turbo that gives the engine massive torque throughout the speed range. D4 is the in-line 4- cylinder model with a full 3.7 liter displacement. This large swept vol- ume provides the basis for solid per- formance, further enhanced by turbo and – on the high power model – also mechanical compressor. D6 is the in- line 6-cylinder version of the D4, with all the same features in a larger size and 5.5 liter displacement.
