Forward facing propellers have proved to be superior in terms of performance, drivability and not least – fuel consumption.
By working in undisturbed water the propulsion efficiency is far greater than on conventional inboard systems. The fact that the propeller thrust is aimed horizontally means that all power drives the boat forward. Volvo Penta IPS also enables the use of flat-surface hulls, which means the boat can be designed for minimum resistance. 30% less fuel – 40% longer range When it comes to fuel economy, the benefits of Volvo Penta IPS are obvious – an impressive 30% possible reduction of fuel consumption at service speed compared to inboard shafts. That translates into over 40% longer operating range, and of course a huge drop in exhaust emissions.
It seems like an impossible combination, but while decreasing fuel consumption, performance is also greatly improved. In a match-up against inboard shafts of the same power, the differences are obvious. The boat equipped with Volvo Penta IPS accelerates much faster, and has a higher top speed.
Volvo Penta is also making the forward drive technology available all across its small-block V8 lineup, which includes 300, 320, 380 and 430 horsepower engines.
