Quietest small outboard?

Any nominations for the quietest 5ish hp outboard? Presumably it will be a 4-stroke, but is there much difference between makes?

Are the 2.5/3.5hp motors noisier than the 4/5/6s?

You're not trying to sneak up on wIllFish again are you? He's wise to it, and he's waiting brandishing a copy of 'Pigeon Fanciers Weekly'.

IMO the 4/5/6hp motors are significantly quieter.

The twin cylinder motors are quieter (smoother) than the singles, although they generally start at 6hp and are heavier too

The air cooled Hondas I've heard made a right racket.

The air cooled hondas are very noisy, I changed mine for a little Mercury two stroke that was silent in comparison. Going a bit bigger to 6 & 8 hp, the Yamaha 2 strokes are also much quieter than the equivalent Mercury 4 strokes.

Spot on. We experimented with different outboards on my dads sailing boats. Quietest single cylinder 5hp was Yamaha 2 stroke, he bought a 5hp Honda to replace it and it was significantly noisier.

However the 2 cylinder, 6hp+ 4 strokes are really nice and quiet (All major brands)

Is there such a beast a a two cylinder 6hp outboard? A quick look at the specs for the main manufacturers shows everything below 8hp as singles.

Is a 4 stroke single much quieter than the equivalent 2 stroke?
