Totally agree those old yams are solid workhorses, unfortunately they don't meat the emission rules under the new standards. You also can't use the modern 2strokes on most freshwater dams as these are used as our drinking water.

The gap has really closed up. My Merc 115 4 stroke is 163kg (dry weight, long shaft), which is the lightest engine I could find at the time. The next lightest was the 115 Opti at 170kg, then the Eninrude and twatsoo at 177 and 178kg. I'll admit, the heaviest in the range is a 4 stroke though. The Honda at a monstrous 217kg. The new merc is about the same weight as a 1986 Evinrude 120 loop induction (according to the best info I found).

I chose the 4 stroke on weight, but it would have been a 2st had they been lighter. I do like the quiet and greatly reduced smell though.

Not really too qualified to comment on this one but for me ,I was just chuffed to get out of the old inboard scenario ,especially when you look at the whole picture ,my ally highfield 5m with 90hp four stroke honda(@163kg) sits on an unbraked trailer ,and that's a big bonus in my book ,only real concern was when somebody suggested it was a Honda Jazz engine on its side ,I had to question whether in my early fifties I was really ready for a Honda Jazz .. (sorry only 25 hours so far)

Those were a great engine, I sold a boat with a 90 Honda with over 5000 hrs and there are plenty with way more than that on them from the commercial side. You often find engines that run longer hours per day will out last the ones that do a short trip then allow the engine to cool before blasting off on another short trip. The Honda jazz was an extremely good little car, the body normally gave up the ghost well before the engine.

Not sure that a spark ignited 2 stroke diesel is the way forwards, without the high compression there really is not much benefit in diesel... However as the Navy don't like to carry petrol on board their ships, needed something to fill the gap.

I'm not dissing the etec but there is no mention of the props on each engine.

I notice the etec 40 has a nice shiny stainless job on it.

Yes the E-tecs ship with a stainless prop. I guess just another tick in the box for E-TEC

However interesting to note that all the outboards give similar top end speeds other than the e-tec 30, suggesting they are propped correctly.
