Yamaha/Mercury Four Strokes

I am looking for a 40-50 four stroke tiller and when looking at the specifications for the 40hp and 50hp motors the displacement and weight figures are very very close.

I thought Mercury was on their own since 2006 I believe in regards to 4 stroke motor production. But maybe not?

Any other feedback on 4 strokes this size? thanks

I’ve ran a 60hp Yamaha since 2008, it’s been flawless!

There isn’t much difference in those motors. a little change in the computer. basically same motor.

Not a 40-50hp but I like my 60 yamaha. Only had it for a couple weeks now but it’s sweet. Trolls down nice and gets up on plane fast. It’s not to big for my Modv Jon at 18′ 6″ boat weights in at 700 dry. Pushes along at 42wot with me full 7gal tank and 2 batteries up front and 1 in back and gear. Happy with service so far with yamaha and dealer checking in on how it’s running.

I run a 40HP older carbed Yamaha 4 srtk. Been a great motor for me. I do take some extra precautions in draining the carbs when not using it for extended periods. I also have a 10 micron inline filter I use so the carbs don’t get plugged.
