I wouldn't go back to a 2 stroke, I'm sure the same would be true for 2 verses 4 stroke 40hp comparison. The fuel consumption difference makes it a no brainer. My son has a 2 stroke 25 Nissan on his 1844 tunnel. We fished all the same spots one day in the Burns. He was by himself, my wife was in the boat with me. When we got back to the launch he was running on fumes, I had burnt 2 gallons.
I've heard the new Tohatsu 40 four strokes are slightly faster than the Tohatsu 2 strokes. I haven't run one yet myself though.

Sounds like you and your son have very similar boats. Besides fuel economy, how do your motors compare performance wise?

I can't speak for the 25, but I have a 2016 tohatsu 30 hp four stroke. I had a 2000 model 30 hp tohatsu two stroke and the new motor performs better. Better holeshot, better load carrying. I haven't gotten top end numbers loaded down yet but I am confident it will be better than my old motor by about 2 mph. I can't believe it gets a loaded boat on plane as well as it does. I run an alweld 1448

Mine is a light gauge Alweld. GPS at 26 with just me, fishing gear, Minkota 80, 3 batteries and an Atlas jack plate as extra weight. Running an 11 pitch prop for better holeshot. 12 pitch only got me 1 more mph but holeshot suffered. It's the best all around marsh setup I've had yet.
My son's is a Styron shop built hull. Appears to be very similar weight wise to mine. He has a rebuilt 1993 25 Nissan. I think he is running a 13 pitch prop. GPS at 29-30 with him, 12V trolling motor, 1 battery and fishing gear. He travels a lot lighter than I do. We both wieght in the 245-250 lb range. The old motor performs really well, mpg just sucks.

When the sun hits it just right the dark blue Tohatsu looks black. Close enough for me.

Even though Tohatsu builds ALL Mercury motors 30hp and under, and they build ALL Nissan outboards, neither of them got the new gear ratio. Mercury has a 1.92 ratio which sucks on hole shot. The 2015 and newer tohatsu 25 and 30 has a 2.08 gear ratio, a stump puller. I tested the 25, it is a nice unit. No other new 25 will run with it in the marsh.
As for a new 40hp outboard, tohatsu 40 is 53ci. There's no replacement for displacement! That is why APBA races motors by cubic inch rating, there is no fair way to race otherwise.
