It also had a powerhead-mounted oil tank, weight of 70 hp yamaha 2 stroke, saving valuable onboard space in a small hull. Available in only one model with longshaft and remote control, the OEDA one-star-rated Yamaha 70B develops 69hp at rpm from its three-cylinder loopcharged cc powerhead and has a WOT range of rpm. The engine is fitted with electronic ignition-timing advance and a cold-start fuel primer, eliminating the need to fiddle with electric chokes, but the 80W alternator is a bit weak and needs upgrading in line with the direct competition.

If anything, I would definitely give the edge in 'overall' performance to the F What this allowed one to do is research outboards by model and year to see what the actual rated power was.

I have tried several Yamaha 70B outboard motors on a variety of hulls since my first review, but the best combination was the old Haines Hunter R runabout rated to 90hp with the 70B engine swinging a 19in stainless steel prop. It also had a powerhead-mounted oil tank, saving valuable onboard space in a small hull. The classic Yamaha HP two-stroke-power-cycle engine was not particularly powerful. Yes--the boat was loaded beyond recommended capacity but the water was extremely glassy and we took our time. Of course the modern F70 is much easier to live with than the old two-strokes: less noise and smoke, idles forever without fouling plugs, and dramatically better mileage. A new Yamaha four-stroke-power-cycle F70 will probably weigh more than the classic 70, and the extra weight will take maybe 1- or 2-MPH off the top speed. My Boston Whaler 15 had a Yamaha 70 two-stroke-power-cycle engine. Post by El Rollo » Tue Nov 21, pm. OEDA Stars. Post by jimh » Thu Nov 16, am. You can expect similar performance overall, but the characteristics are different.

We have put together a comprehensive weight chart for all current Yamaha outboard models, making it easier than ever to compare the different power and shaft options. Dry weight refers to the total weight of the motor without any fluids, such as engine oil, or gear oil. Generally, a higher value is more desirable, as it indicates better performance.

Provided the anti-ventilation plate was kept at least three-quarters immersed power astern was good. Available in only one model with longshaft and remote control, the OEDA one-star-rated Yamaha 70B develops 69hp at rpm from its three-cylinder loopcharged cc powerhead and has a WOT range of rpm. I recommend indexing the plugs on the F As for performance, I cannot say what the total horsepower is for either the engine, but I can say that it seems extremely close. What this allowed one to do is research outboards by model and year to see what the actual rated power was. I used to own a pair of them. As always with proper outboard performance, the propeller is all-important, as is mounting height. You can expect similar performance overall, but the characteristics are different. Good Luck with your decision. In years past when looking through all the data, generally the 4 stroke offerings were a little softer on power than their comparable 2 stroke counterparts.
