2 Stroke or 4 Stroke?

carus007 · 28 July 2013, 20:05

Hi guys,

Just wondering what are the main differences in these engines?

Which one is more reliable?

Which delivers more power?

Pro and cons

Mainly looking at the 3.3 HP Mariner 2 stroke and the 3.5 HP Mariner 4 stroke (Modern version)

In terms of power, the 3.3 will give you roughly about 3.3hp and the 3.5 about 3.5hp. ;-) With tiddlers, weight is usually the deciding factor 'coz you're gonna carry it. Buy the lightest. :-)

Already have the Mariner 3.3 2 stroke, works well, starts first pull.

But my mate has offered me a 2009 Mariner 3.5 mint condition, Like new for £300.

Like the 3.3 but just wondering if the 3.5 would be any better as being the newer more up to date model?

The 3.5 will be just as noisy, heavier, a bit more economical, but will be more fussy about being stored/transported.

Why not ask your mate if you can try his motor out for an afternoon, to help you decide?

Yes I was thinking that.

I have seen it, It runs nice and is in Gleaming condition.

Looks that bit more up to date than mine,

Plus it has a twist throttle, mine is controlled my the main head.

How much for your 2s 3.3? What model is it? Where are you based? PM me.

You will find the longer tiller arm and twist grip much better, and not needing to mix fuel is an advantage.

But those little 3.3s are the ultimate portable engines.

Owning a two stroke oil puking machine, I will always say get a 4 stroke.

it also depends on if you can lie the 4 stroke down on the right side all the time. yes they are great wee engines but lay it down on the wrong side and you will be in a whole world of pain.

I just bought a new Evinrude ETEC 2-stroke, and I LOVE it. I'd never get a 4-stroke if I could have one of these as an alternative.
