Its not a 225 4 stroke Suzuki, its an old two stroke efi one the same as codprawns, as used on Noahs ark

Looks like an older engine than mine but it's hard to see from the photos. They are brilliant engines and they use no more fuel than the modern stuff - about 4mpg cruising - same as most people report their 4 strokes are doing!!!

Much lighter than a 4 stroke and much more acceleration!!!

At least it can get the Ark onto the plane - a 4 stroke would never manage!!!

i doubt if your engine returns the same consumption as DFI 2 strokes and 4 strokes unless you have got a very very special engine, i agree at wot there is not a lot in it but at lower revs the other engines are proved to be more economical by a long way.
i used to have a suzuki 85 and that could not get fuel thru it quick enough and changing to a honda 90 made a huge difference for river work and gentle cruising.

Does 2 spark plugs per cylinder - fuel injection and ceramic reinforced pistons with boron cylinder walls qualify???

Seriously I read on here how much people are using with their 4 strokes and my setup seems about the same. Maybe under 1/2 throttle there is a difference but my boat is very rarely driven like that!!!

your boat is quite a big beast and the engine is quite small in comparison so i expect you are having to push the engine most of the time to get reasonable performace,

if you are getting around 1l -1.1l to the mile then i would say you must be chuffed to bits if that is typically at the higher throttle settings.

i seem to average out at 1l to the mile on mine, need to compare this to the latest run out we had at the weekend but for me 1l to the mile is very good and very happy with that. i would have thought i would have used a lot more fuel if my engine was pushing a lot bigger/heavier/wider boat.

I get about 4mpg when cruising about 4000rpm. Flat out it hits 85-90 lph which is exactly the same as the 4 stroke. If it wasn't for the obscene price of fuel I would be quite happy with the cruising figures.

Yes my engine does have to work quite hard but it's mainly down to the fact the hull is so good - it just feels slow unless you are out in a Force 6 or above!!! Imagine how good my engine would be on a lighter boat - not bad for an "old design"!!!

i could imagine you would be getting loads more mpg on a smaller lighter boat.

when you come to sell it to get a 300 i expect there will be quite a queue for it.

Don't know if I will - it's such a lovely engine - may keep it and find a nice fletcher 199 or Ring 21 to stick it on!!!
