135 Mercury 4 stroke?

I agree thier must be a large torque difference between the 140 suzi and the 135 merc

When i was shopping for motors someone recommended I get 150hp instead of the 135 merc as they had a similar Glacier Bay with 140 hp suzukis that needed 4500 rpm to make 20 knots.
The Merc 135 only requires 3700 rpm ( full fuel / 3 people) to achieve 20 knots

The suzi uses significantly less fuel at the same rpm of course tho according to this website below

fuel use at the same rpm is a useless comparison. So is litres per hour. A true comparison has to take into account the speed that is being achieved. If both boat/outboard combos are doing 20 knots for example, which one is using less fuel at the same speed? Who is going to use less fuel getting to their destination at the same time?

the 140 Suzi is often bagged for being gutless etc, but it takes a while to figure out how it generates its power. I reckon they should shorten the throttle length to increase revs with less pushing of the throttle to work better with the motors strengths. I went from the big V6 200 Suzi that loved to cruise about 3800ish to the 140 that cruises at about 45-5000 (on different boat). Fuel use on the 140 is great, despite the much higher revs. On my 19' Cruise Craft, I have to push it up over 5500 rpm to get worse than 1l per nm, and that's over 30 kts!

Looking to buy a motor in this range in the next couple of months so have been following this thread.
The Merc 135 is going to be a bit too heavy so the Zuk 140 looks ok but was wondering if anyone has had any experience with the new Yammie 130. Any info appreaceated.

i looked at the yamaha but the prices were more than the others plus it is only a 1.8 ltr so likely less torque than the suzuki. The Mercury 115 is pretty well priced at the moment with the deals they have on, i looked at this as well. "apparently" its output is more than 115.

It's pretty much bang on 115hp (I believe Mercury claims 113hp to be exact in EPA filings), but at 2.1L it's a big 115, so the torque curve is going to be superior to everything in class this side of a V4 E-TEC. I water tested a command thrust 115 and they are really nice, the big gearcase helps a lot.
