I never knew that Yamaha still had a manual-start version of its long-running 50H Tiller Steer outboard motor — until I tried one last year. Originally released on the Australian market in , this was the engine from which Yamaha developed its 40V. In commercial circles this engine tends to be overshadowed by the Yamaha Enduro 40 and 60, which are incredibly popular in Africa, South America and the Pacific Islands. The Yamaha 40 has a gear ratio and the 60 has a hefty 2. Still, for tiller-steer planing hulls the taller ratio does reduce prop-steer torque when planing, whereas the Yamaha Enduro 60 really builds up your arm muscles. Having three cylinders, the cc Yamaha 50H is much easier to start than the cc twin-cylinder Enduro It also idles and trolls more smoothly, whereas the 40 tends to shake your teeth out below rpm.

YDC delivers superior anti-corrosion properties that Yamaha outboards are legendary for. Loop-charged scavenging creates a circular fuel flow for efficient transfer of exhaust gas and even distribution of the air-fuel mixture. The result is greater combustion efficiency for excellent performance and better fuel economy. The capacitor discharged ignition system provides strong spark and precise timing, preventing plug fouling, improving starting performance and reducing maintenance. Wide range power tilt and trim allows convenient engine operation and adjustments to the boat attitude to meet changing conditions while underway. Years of research and development have made Yamaha's power trim and tilt units reliable and extremely durable.

Your outboard has a red line which is the maximum RPM it can effectively run without risking damage to the power head. The Yamaha 50H develops AVS Forum. All the floats were replaced with new. Getting about 35 mph when properly trimmed. Years of research and development have made Yamaha's power trim and tilt units reliable and extremely durable. Enquire Now. Your outboard has one forward gear so you need a prop that can make the best out of the power band which is the RPM range the engine is designed to run. Prop diameter, pitch, cup, cup placement, number of blades, rake, blade shape, barrel size, barrel flare, porting etc are all factors that can be combined to make a prop do different things. The filter media breaks down and will cause a massive engine failure Head Wear. Later that day it would start to die randomly while at idle.

There are many more factors involved as to how a prop makes a hull and outboard move than just pitch and three vs four blades. Lots of people think they are able to run a boat but could use some help. Alloy White G Series These props deliver Yamaha's high-quality design and performance in a low-cost, lightweight propeller. They went through and cleaned the carbs and the water line for the cooling system. There is also a myth about hole shot props are four blade and speed props are three blade. Looking for some insight and expertise here before taking it to a mechanic.
