Above is the site that gives you the specs of the 150 & 175. I think the 150 is just a detuned 175.
I run the 150 on c-pearl. I would be interested to know what pitch prop is on the one you get and how it fits getting you into the higher rpm range.
If you join the crowd let me be the first to welcome you 8)

The real difference between the 175 and the 150 is at the top end. I run two 150's on the Tom Cat. On that boat there is no advantage to the 175. I doubt if you would see much difference on the C D 25 either.
The Suzuki is an outstanding engine (but there are several very good outboards in this size).

Unless the weight is substantially higher, you will never be sorry to have too much power. My CD25 has 130 and I wish it was 200. I average (guessing) about 2 smpg, and I am certain that more HP would be more economical for my heavily loaded boat. I have also wished for more umph when on the CR bar swells and the water speed measures four times the GPS speed and the motor is lugging to climb the hill. I think the initial cost difference in your two motor choices will more than cancel itself out over the life of the motor.
I was incorrect on the difference between the 150 and 175. The difference is in the torque in low to mid ranges. This is due to variable valve timing--see the brochure. The two engines have the same block, the same weight, same fuel injection but the 175 has the variable vale timing-to give more torque at the lower end. The Suzuki's have the biggest displacement in this HP range, and swing a larger pitch prop--and slightly larger diameter than some of the others.
I could not find any studies where the 150 and 175 were compared on identical boats--which would better answer your questions. I certainly cannot disagree with Tyboo as long as the boat can handle it, more hp is probably better.

Thanks for your inputs. We went out on the boat with a 150 but had only 20 gals of fuel and no water or other things but pfds. The boat was very responsive and acceleration was great. I was wondering if we loaded it with 100 gals fuel and water and maybe 5 -6 people plus equipment would I wish I had the 175? Sounds like I would??
I have the Suzuki 175 on my 25. I really like it so far, with about 30 hours. I'm still working on the prop. I have a 21" SS Suzuki prop, it seems just a little big, can only get 5300 - 5400 rpm on the motor. I tried a 17" but it was way to small. I'm thinking a 19" might work.
Marc, what do you guys run on the 25 with this motor?

Not if you are running toward Hammond, off the CR bar, on a bull ebb, there are big waves stacked up behind you, and over taking you. When a non-breaking wave overtakes you, it is the vertical displacement of the water that moves; there is no net horizontal motion of the water. All bets off for a breaking wave, though, when the crest topples forward, and then you do have water down your butt!TyBoo":2y5brsjm said:
No idea what the SOG is when the wave breaks across the transom!
Time to fish, Mike!
Dave , We tend to like the 16" diameter Suzuki props for the big bite [ and bow lift] they provide, especially on heavier boats. I think the 3X16"X18.5" would work for you . When we get the next 175 powered 25 on the water [which I believe will be soon] we will try and Ill post numbers . Those 16" props come in 1.5" increments of pitch .

Most of the time we don’t use all of our Suzuki’s 140 hp on our CD 25 turning a 14X17 factory prop. That said, it would be nice to have the extra hp when you have 5-6 people on board, when trying to climb a wave on a trailing sea, or when trying to climb another boat’s large wake while overtaking. If I were to do it again I would opt for twin 90’s or a 200hp OB. The down side is $$$.
On another note the 140 Suzuki is a bit light on the stern of our boat. The 50 foot of chain rode in the bow might account for some of this but the 140 Suzuki is a light motor compared to most. So some extra weight on the stern would be a bonus especially in a trailing sea.

Well Volsman....Which one do we congratulate you on getting? :lol: These are cool boats !
Bob,
I knew the 90/115 shared displacement and it looks like the 140 shares the stroke, so it’s probably just a larger bore and fuel system. I’d opt for more weight and hp if I had to do it all over again. That said, we still rarely use all the hp we have now, it would be nice to add some weight and have some reserve at times. All said the Suzuki 140 is a quiet smooth running engine with very adequate power. I put my big cooler and extra water to add some ballast in the stern.
