Does anyone have any real world experience with different 4 stroke 25 HP outboards?

I can't seem to find real world fuel consumption from Suzuki, Evinrude, Mercury. Yamaha has theirs posted but I was surprised that their fuel burn seemed a lot closer to my 2-stroke than I originally thought. I need to get a 1 gallon jug and just measure it out more accurately.

I have been on the fence about upgrading to a four stroke for the last 4 months, I can't seem to make the leap.

What your average fuel burn on your 25 2 stroke? Mine is 1.25 gph roughly. The Yamaha 25 4 stroke is a beast and has a lot of low end. It’s a heavy motor than the 2 stroke but I think it would make up for it with the low end. I would call the Yamaha four stroke burn closer to 1gph just ballparking. It does suck more fuel than the 20hps

I think my fuel burn is more than that. Closer to 2-2.5 gph with a fresh power head and carb clean/tune this is pretty close to the studies ive seen for the 2 strokes. The Yamaha Website on their test platforms has a fuel burn max of 2.8 gph with an average cruise burn of 2.1? I've been really happy with the 2 stroke umph down low with my old stainless prop. I need to throw an Powertech SRA prop on it I think though.

The big fuel efficiency is seen on the big motors.

The draw is how quiet they run.

Keep the two stroke and quit playing

Don't go to the dark side.

I have a SRA3 for a Yamaha if you want to try it out. Can’t remember the pitch off top of my head but it’s 12 or 13

I'd take you up on that in a heart beat! I run a 13 now!

Just checked it’s a 12. If you still want to test it I’ll PM my number so we can figure out details.

Tohatsu still lists a 25 and 30 horse two stroke motors on their website. 112 pounds. Prolly only available outside the US?

Probably. It might be like the mercury seapro series same old 2 stroke but only available outside US

Fwiw, the relatively new ( 2-3yrs ??) Yamaha F25s 4 stroke weighs only 126lbs. There have been some reviews on this forum.......

From a review on the web the F25c uses 9.10 litres per hour and does 23 knots WOT. That converts to 26 mph and 2 gallons per hour. 13 MPG WOT is better than my Yammy 25 2 stroke. The boat used was an aluminum V hull that weighs 376 lbs.

The electric start is 132 lbs. 126 lbs for manual start.
