Outboard noise levels

[codprawn]

Everything I have read lately informs me that modern 4 stroke outboards are the way to go for quietness. Other then say the new Etecs are also very quiet. Old 2 strokes are noisy and smoky.

Yesterday I skived off a job for 2 hours and stood watching boats coming in and out of a small harbour - it was high tide and weather stunning!!!

None of the outboards seemed that noisy anyway but some were better than others - what really suprised me was that an old shetland I saw with a nail of a 40hp Evinrude was actually quieter than a boat with a new Mercury 4 stroke!!!

Another guy had a new Evinrude about 60hp or so - that was pretty quiet but even quieter was an old Suzuki 2 stroke oil injection.

Yes, but isn't a 2 stroke carb V6 outboard on hard acceleration a glorious noise. Even better with 6 holes drilled in the leg

I currently have a Suzuki DF140hp 4 Stroke which is ultra quiet, everyone who has been on my rib always end up saying " I cannot believe how quiet your engine is" even other boat owners as I go through the Lock at Chichester Marina say "if only my engine was a quiet as yours!!"

I have the same engine as N.B. and it's a real luxury having such a quiet motor

I agree with Pete, wonderful noise.

The resaon to have a noisy motor in the first place is that people hear you coming and get out of the way!!!!!!!!!!!!!
There is nothing like twin yams going flat out!!!!!!
But then I am just an anti social git.

On the same subject - nothing beats the sound of a spitfire with the RR merlin engine going into a shallow dive...

We are all just petrol heads at heart, can't agree more about the merlin.
Have you ever heard one of the old MTBs with twin meteors, which I think is the marinised merlin.

Yes Nasher - thats a good sound as well- but that "spitfire" sound when its just coming down towards you- just makes you feel good , and all goose pimples
inside- it means business, and its beautiful at the same time.

This is the CMB (early MTB) that my grandfather commanded in WW1 it was made by Thorneycroft with twin V12 petrols producing 1000hp so basically all fuel tank and engines.....oh it also had a couple of torpedoes as well
Interestingly it had a stepped hull , so there is a new idea and could do 40 knots Des
