- Much heavier than 4strokes (!!!!!)
- Not as tough as old 2strokes.

OK, you may lay them in the floor on both sides. But quoting E-Tec engines in this thread is absurd.

But E-Tec small outboards (i.e. 15hp) do not have any advantage vs. 4 strokes.Smallest Etec is actually 25hp so is probably just outside the scope of this discussion
- Much heavier than 4strokes (!!!!!) Eh! The lightest 25hp Etec is 66kg, the lightest 4s Yammy is 76KG
- Not as tough as old 2strokes. Says who, I'll fight you for it

OK, you may lay them in the floor on both sides. But quoting E-Tec engines in this thread is absurd Absurd is a bit strong, slightly irrelevant maybe, but so is saying that 2strokes are banned on inland waters & production has ceased. .
We wouldn't want to cause any confusion, would we?

So get yourself a nice 25hp 2 stroke and you'll be handling the same weight but have an extra 15hp to play with.

my mariner 20 4 stroke only weighs 50kg not much more than a two stroke,its quiet,no expensive two stroke oil,consumes less fuel than an equivalent two stroke,and burns clean.
Dare i say four strokes are less complicated than a modern injected two stroke
servicing a four stroke has a few additional items,oil and filter and a new easily changed cam belt every three or four years with the addition of valve clearance adjustments if ever needed.
this is easy to do and parts can be obtained cheaply.
But overall cruising up a river quietly with no smoke wins it every time for me

I loved the lower weight and power (torque in midrange) and simplicity of my previous 2 smokes.... Great for racing....

But the noise after a while!!!! My 4 stroke is so smooth and quiet.....

For performance all round, stick to 2 stroke.. for refinement buy 4 stroke...

we are talking about small outboards, not large modern air scavenging 2 strokes

perfectly put, a four stroke is a day in day out allrounder

and the honda 20hp short shaft is only 47kg.

they also attended the UK's largest boat show as did suzi, yamaha, mercury/ mariner, Tohatsu etc but amazingly Evinrude were the only manufacture that didnt and have a UK office for marine staff like most other manufactures apart from Evinrude!

back to OP question. 2 stroke if you are looking for max power to weight ratio and have a limited budget as they are cheaper 2nd hand than 4 strokes. yes they are older but they also dont cost silly money 2nd hand.

Love the idea of 2 stroke power to weight ratio but preferred the benefits to buy a new, so channelled down the 4 stroke route. Finally decided on a Suzuki DF20A short shaft, fuel injected, at 44kg not a massive weight penalty over 2 strokes, and just manageable to lug around single handed - boat left inflated but engine removed after use. Early days but not regretting it so far - quiet, powerful, economical and under warranty.
