Volvo Penta 290 SP-A Ratio 1.61 Complete Sterndrives

Volvo Penta 290 SP-A system is a stern drive (inboard-outboard), where the engine is housed inside the boat, but the drive unit extends out the back of the boat, providing propulsion through the water via the propeller. This setup combines the efficiency of an inboard engine with the maneuverability of an outboard system. Volvo Penta 290 SP-A with the 1.61:1 gear ratio is a versatile and reliable stern drive system that offers a balanced combination of performance, durability, and efficiency. It’s well-suited for a variety of recreational boating applications, providing smooth power delivery and handling for both everyday cruising and more performance-oriented needs.

Features :

• Shift and throttle cables (or electronic controls, depending on the setup) and linkages for steering and throttle control are often included in the complete package.
• The 1.61:1 ratio indicates the reduction gear ratio of the drive, meaning for every 1.61 revolutions of the engine, the propeller completes one full rotation. This gear ratio is balanced for both good acceleration and cruising speed, making it versatile for a wide range of recreational boats.
