Power Packs

Which Reversible Power Pack For Me?

If you need help feel free to email or call us and we'd be happy to assist you with determining with Lecomble & Schmitt reversible power pack is the correct one for your specific application. Or you can use one of the two formulas below.

For boats equipped with a hydraulic steering, it will be necessary to determine:

• The volume of the steering cylinder (take the biggest volume in case of a single rod cylinder).
• Available voltage on board (12 VDC, 24 VDC, etc.)

For planing or semi-planing hulls, the power pack will be selected in function of its flow rate so that the steering cylinder will run its complete stroke (lock to lock) within 10 to 12 seconds.

For displacement hulls, the power pack flow rate must enable the steering cylinder to run its complete stroke (lock to lock) within 15 to 17 seconds.

Examples:

Speed boat, planing hull with a 239cc cylinder – Available voltage 12 VDC

"Required time" is the time the cylinder will take to travel lock to lock. After completing the calculation we can determine that the flow rate of the required power pack will be 1.19 liter/minute, therefore we will select a reversible power pack with adjustable flow rate type RV2.

A boat, displacement hull with a 707cc cylinder – Available voltage 24 VDC

"Required time" is the time the cylinder will take to travel lock to lock. After completing the calculation we can determine that the flow rate of the required power pack will be 2.8 liters/minute, therefore we will select a power pack type RV3.
