PRODUCTS Yamaha unveils newly designed F350
Yamaha has unveiled a newly designed F350 outboard along with new Helm Master EX features and more pitch options for Saltwater Series II propellers. “The F350 is the perfect big-power, lightweight option for a wide variety of applications,” Ben Speciale, president, Yamaha U.S. Marine Business Unit, said in a statement. “In addition, we expanded Helm Master EX variable-speed bow thruster integration for single through quint configurations to give more boaters access to the ultimate in boat control. We also added new pitches to the reliable Saltwater Series II propeller line, giving a broader array of boats access to great performance and fuel economy.”
The 4.3-litre V6 F350 has larger intake and exhaust valves than the F300 and uses the same diameter electronic throttle valve as the 450-hp 5.6-liter V8 XTO. A new crankshaft design offers a longer compression stroke, which should provide more torque at lower speeds. The engine has an 11-to-1 compression ratio, and tailored intake manifolds have surge tanks that are 40% larger than those on the F300. The 81mm electronic throttle valve is 8% larger than the 300’s valve and is center mounted.
New MX4 is a four-blade evolution of the company’s flagship series
The MX4 is a four-blade evolution of Sharrow Marine’s flagship MX propeller series, first introduced in 2020, and uses the same True Advance technology to deliver maximum efficiency and performance, now for larger and heavier boats.
Unlike traditional four-blade propellers that compromise top-end speed, the MX4 propeller is said to outperform even the fastest three-blade options on the market. In a recent test on the MJM 43z powered by triple 300hp Mercurys, results showed that the MX4 was faster than conventional three-blade propellers at every RPM from idle to WOT.
New ECO Pro thrusters from Max Power
Max Power, the Lalizas-owned thruster manufacturer from Italy, has launched its new ECO Proportional range of brushless thrusters.
Max Power describes the ECO Pro series as an “evolution in the market of thrusters” due to its AC brushless electric motor, resulting in reduced power consumption. It consists of three models based on their thrust – the ECO Pro 90, ECO Pro 110 and ECO Pro 130 for boats from 28ft-60ft in length.
The AC brushless motors offer numerous advantages compared to traditional DC ones, says Lalizas, including increased energy efficiency, power density, durability, reliability, less noise, less vibration during operation and no maintenance.
Due to the high efficiency of the AC brushless motor, ECO Pro thrusters consume much less energy of what the DC conventional thrusters do. Offering more than 95% efficiency means that the motor does not generate heat, so the temperature is almost stable, and the motor can work for a long period of time.
