Low speed for marine diesel engines

Low Speed Mode is an ideal feature for docking, exploring canals, or slow-speed trolling while fishing. When activated, your boat’s idling speed can be reduced by up to 50%, from 5-6 knots to 2-3 knots, with simple adjustments using the throttle/gear lever.
Adapt to your adventure

Maneuver with ease

Focus fully on operating your boat when you activate Low Speed Mode, giving you more time for maneuvers and adjustments. Enhanced drivability and improved control at reduced speeds make operating in tight spaces easier.
Marine excursions

Reliable and straightforward

Time on the water should feel like a getaway. Whether navigating a busy marina or cruising through an inland waterway, experience enhanced control and improved manageability. Low Speed Mode is available for Volvo Penta engines from D3 and up.
The low speed function

How it works

In Low Speed Mode, within the first 12 degrees of throttle lever movement, the engine remains at idle while your boat’s speed is moderated by a 50% transmission slip. Once the lever exceeds 12 degrees, the gearbox fully engages, allowing speed to be controlled by the engine's rpm.
Low speed marine experience

Effortless and precise. A Volvo Penta dealer can assist in adjusting the angles where the clutch and slip reduction are controlled, ranging from a minimum of 25% to a maximum of 75%. Experience improved maneuverability at low speeds, all controlled with a single lever.
