Volvo Penta IPS: The future of Inboard Marine Performance
Article Page 5: Dockside Handling

What Are The Advantages of Inboard Performance System?

Volvo Penta IPS sets a new, higher standard for marine diesel engine efficiency, vessel performance, operator enjoyment and boat builder ease of installation.

In a comparative sea trial between two identical boats with the same installed diesel power (370HP), Volvo Penta IPS achieved 6 knots faster top speed, consumed 30% less fuel at 30 knots and had 15% better acceleration time out of the hole. In the same test, sound decibel level readings were up to 50% lower on board the Volvo Penta IPS compared to the conventionally propelled sister ship.

Exhaust fumes are truly minimized with the Inboard Performance System because the Volvo Penta D6 has very low exhaust emissions. The exhaust is emitted underwater into the propeller wash through the propulsion unit.

Volvo Penta IPS has extremely low service requirements since there is no need for shaft alignment, and all running gear exposed to seawater is fabricated of either bronze or stainless steel, yielding excellent corrosion resistance. Routine maintenance includes an annual visual inspection and anode change while an oil and filter change is to be scheduled at the earlier of 2 years or 400 hours of operation.

Should there be a severe impact or grounding, the propulsion unit is designed to part from the vessel at predetermined separation points.

This may reduce the likelihood of hull penetration and resultant fiberglass repair which is common in groundings of a conventional inboard shaft, strut and rudder arrangement.

Overall engine maintenance is made easier by the space created by the system’s compact envelope. With no need for a large exhaust muffler system in the engine room, engine access and inspections are facilitated.

Whether you are a boat owner looking to improve performance without sacrificing fuel economy or a boat builder looking for ways to offer more value to your customers, Volvo Penta’s Inboard Performance System is without a doubt, the solution.

I for one will want it on any powerboat I buy over 38 feet... just for the performance improvement alone. Or, is that performance savings?
