Does Yamaha still make 2-stroke outboard engines?
Yamaha and Mercury have stopped producing direct-injection 2-stroke outboards (Tohatsu still builds a few), but the latest-generation 4-strokes weigh the same as 2-strokes and offer the latest digital advances.

When did Yamaha start making 4 stroke outboards?
1980
Yamaha first began work on developing 4-stroke outboard motors in 1980. In 1984, it launched production of a 232 cc engine with 9.9 horsepower, the F9.
What should I look for when buying a 2 stroke outboard?
Used Outboard Check 2: Visual Inspection for Damage Give the outboard motor a thorough visual inspection. Check out the cowl to make sure it’s undamaged and in good condition. If the cowl looks brand new, make sure to ask why. Inspect the propeller for damage and for debris around the shaft.
Why are Yamaha outboards so expensive?
Boat motors (outboards) are expensive because they are equipped with high-quality parts that are not only designed to resist constant working at max RPMs but made with materials meant to resist corrosion well. All of this needs significant work in R&D (more money), resulting in a pricey product.

It had proposed a ban on two-stroke three-wheelers from April 1, 2019.
Which is better 2 or 4 stroke outboard?
Because a 2-stroke engine only uses two piston strokes to generate one revolution of crankshaft power, it generates much more power than a 4-stroke engine of the same horsepower. This gives 2-strokes better top-end speed and acceleration. 2-stroke outboards are ideal for use on smaller boats.
When did they stop making 2-stroke boat motors?
In 2004, the Environmental Protection Agency (EPA) put an end to the 2-strokes dominance by enacting stricter limits on pollutants, and then in 2007, making the restrictions even stricter. It became evident that it would be necessary for the 2-stroke outboards to be re-engineered to become quieter and cleaner running.
