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. At 80kg the 50H is 7kg heavier than the single-carbie Enduro 40, but 22kg lighter than the cc three-cylinder Enduro 60 which, like the 50H, has three carbies. Of course, the Yamaha 50H is up-rated from its 40V counterpart whereas the Yamaha 60 is de-rated from its 70B counterpart, so it develops at lot more torque. The Yamaha 50H develops Consequently, the fuel was a bit stale, but after a couple of tugs of the recoil starter the engine roared to life. It was only after 15 minutes or more of idling and trolling that oil smoke started to appear on the post break-in 10 hours on mix of unleaded petrol and oil make unknown at

Make sure fuel pump is rebuilt, fuel system from tank is clean and in good operating condition and if you are skeptical, run on a remote tank with fresh gas and make sure the spark plugs are clean if not new. I have been running straight gas since it does have the oil injection system. JavaScript is disabled.

For a boat owner, understanding how to read and use a Yamaha 50 Hp Wiring Diagram can be crucial for running the engine correctly.

Perfecta pump

Not sure what pitch I have on mine right now but it seems like I can pump it up some. Providing the anti-ventilation plate was kept immersed, power astern was good and no cooling water starvation occurred. Small black plastic piece that threads onto rod with ball and socket. 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. Your input is appreciated!! Anti Corrosion Yamaha's unique marine alloy, YDC, has been developed exclusively to handle the harshest of marine environments and is the result of years of Yamaha research and testing. The Fission is unusual in that it has a broad 2. I ended up doing the following: cleaned gas tank, replaced all fittings, replaced gas line from tank to motor, replaced bulb, replaced onboard fuel filter, replaced motor fuel filter, replaced gas pump, cleaned jets and carbs. Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. The shallow water drive system allows the engine to be quickly set and operated at a tilted angle allowing safe navigation through shallow water.

Run like a top but slow to get up and would only run Took the carbs out again, cleaned, and replaced the floats and gaskets. Power Tilt and Trim Wide range power tilt and trim allows convenient engine operation and adjustments to the boat attitude to meet changing conditions while underway. I may try to cup it some.

The capacitor discharged ignition system provides strong spark and precise timing, preventing plug fouling, improving starting performance and reducing maintenance. Transom Height mm [inch] S: [ Good Luck! I think instead of thinking you need to tell Jack Foreman what to do to make that prop work you should give him numbers and how those numbers change in different scenarios.
