Generally speaking if only cruising then diesel !

2 strokes - slightly lighter than most 4 strokes, simpler to maintain, more grunt and acceleration from the get go, noisier than most 4 strokes, thirsty in terms of petrol and oil. and dont like spending alot of time going very slow.

4 strokes - quiet, sophisticated, slightly heavier than 2 strokes, more complicated than 2 strokes, better fuel economy generally.

having said that the most modern 2 strokes are much better than older 2 strokes in terms of emissions and fuel economy.

so im not sure I have any answer for you.

Very few two stroke motor bikes these days, don't know of any two stroke cars. This side of the pond I would say 80-90% of boats are 4 stroke. Maritime, marine rescue, water police, house hire boats, comercial fishing boats etc all use 4 strokes here. https://www.boatsales.com.au/editori...e-2018-111436/

Is that because they are “ better”? & if so better for whom, the consumer, manufacturers, dealers? Modern 2 strokes are generally lighter, easier ( cheaper) to maintain, better power:weight, higher torque ( better hole shot) than 4 strokes. On paper 2s are a much better option for marine use than 4s, so why the demise? Clever marketing, lack of dealer support (dealers make MUCH more money servicing 4strokes), consumer ignorance (2 strokes are illegal.....aren’t they??), environmental concerns (modern 2 strokes are as clean if not cleaner than 4s, especially when you take the disposal of used engine oil into account)

Nope, fell for the hype & bought a 4s. It’s already cost more in servicing in 3 years than my twin Etecs cost in 6.[emoji849] hey ho!

some interesting points below OMO 4 stroke for me had both so been in both camps with ribs, sibs, cabin boats & dories had a ride in a rib with a diesel outboard years ago [crap]

Careful Dave people might get the impression Yorkshire Folk just like a good Moan

I'm afraid You were always gonna miss those 90 horses on a New Boat less than a meter shorter and a much deeper V Hull Mate.
....But surly If it's THAT Bad... why suffer?

[Inflatable]

Short answer 4 stroke my opinion

[Bushrider]

5 years long distance with 2 stroke [emoji12]

You know me, only happy when I’m miserable.
I’ve seriously considered swapping the engine, even got clearance from Mrs PD to do so “as long as it made me happy”...... I thought that was a big ask[emoji6]
I suppose after having a 585 with a 175 DI 2 stroke & a 6.4 with twin 115 Etecs, my expectations were maybe too high of the DF140. After jiggling about with props & engine height, I think I’m probably getting the best out of it, I just miss the grunt & kick in the pants you get with a 2 stroke.
I would still maintain that the mechanical simplicity of 2 strokes suits the marine environment better that 4s, but that’s just my opinion fwiw.
