merc 150 verado vs merc 150 4 stroke

[lembo]

hi guys
im not really a mercury fan but been reading a bit about there new 4 stroke range and been reading very good things about them.
in particular the 150 hp sze. but mercury are a bit different and offer 2 very different 4 strokes in the 150 size. the standard 150 and the verado.
I know the verado is supercharged but its the heavier of the two but has a much smaller engine at only 1.7 litres where the standard 150 is quite lighter but has biggest out of all 150s at 3 litres.
anyone know how these two would compare ? obviously the supercharger adds weight and power but how is the torque ? id imagine the 3 litre standard model would have great torque?
anyone with more knowledge then me care to comment?
and what is the best 4 stroke 150 on the market? and why
any pros and cons would be appreciated.

Are you aware Mercury are releasing a new 135hp based on there 150hp fourstrokes?

yeah I have read about that, looks like a de tuned 150 . there making some nice motors .
there 115 looks great too big displacement and light as.

[LittleSkipper]

Believe it or not but there entire range from 75-115 are all 2.1 L. They tweak each one to give more or less KW at the prop and change the gear casing for the command thrust models.

As I have said before, I can't imagine the 75HP being a good seller, it is simply way too heavy for the HP, the Verado compared to the "standard" 150 is a whole different engine, the Verado is like a formula 1 compared to a HR Holden, both motors have the same HP, but one is modern hi tech, the other is simple low tech compared to what else is around, it is a simple choice really, do you want "old fashioned" thinking of HP being directly related to size, or the same HP extracted by technology from a smaller engine?

I own a Verado 150 and it's a pretty amazing engine. The same engine is supplied from 135HP to 200HP with different ECU tunes being the main supplier of horsepower differences. The guy who adjusted my ECU tells me it is possible to get 400hp out of the L4 Supercharged engine, however reliability is affected. An acquaintance down south went higher with his ECU tune and often blows Supercharger hoses off. The standard 150 Verado, out of the box is very torquey down low, and feels similar to a two stroke. Mine is currently running a 26" 4 Blade Trophy 4 prop to 6410rpm. If you are running a performance hull, nothing beats the sound of the Supercharger at high revs.

Out of interest what is the difference in economy between the two?

[aussiebasser]

No idea. I'm spending my time at either full throttle or dead idle, I don't worry too much about fuel usage because I know it will be bad at the rev ranges I run.

I'm running a pair of the Mercury 150 four strokes (3L) and I have nothing to complain about.
I'm regularly pushing 3.5-3.8t of boat and still getting an average of 1km per L.

Went through the process 18 months ago to re-power with a new 150hp engine. Didn't have any brand in mind, just went to the local dealers to see what they offered. Most didn't seem to interested except the local Mercury dealer, so was more than happy to give them my business.
So my choice came down either the new 150 or the verado.
Would have liked the verado but at an extra 5 grand over the standard 4 stroke, I found the choice easy the standard 150 with 7" vessel view.
As for performance, couldn't be happier, plenty of power and good on the juice.

yeah the standard ones are running big displacements. wonder what the torque curve of the two is like ? and what revs max torque is at. as both produce 150 hp. I normally assume super charger or not the bigger displacement produces more torque. maybe the smaller verado revs harder ? im not sure would love to see a drag on identical hulls.

[mitch_wahoo]

I've got the 150hp 4 stroke too. Plenty of balls. Good on fuel. Only got about 70 hours on it so far but really happy with it.

[juggernaut]

I normally assume super charger or not the bigger displacement produces more torque.

Not necessarily - it will depend how much boost the s/c is making at a given rpm. Very generally, if the 1.7 litre motor was boosted to 14.7 psi (1 atmosphere) it would, in theory, be akin to having a 3.4 litre motor.

[kizza1]

haven driven several of both engines i would go the standard 150 over the verado. you will normally get better economy out of the standard 150.

[FisHard]

I'm only going off what my brain has absorbed from reading about these engines, but I don't understand why the supercharger? Wouldn't it just be another component that could fail? If it made for a lighter package, yeah ok, but no, the verado is heavier! I would go the regular four stroke any day.

[fishwpa]

Don't know anything about the engine (I have the baby merc 60hp efi), but having owned a standard V6 holden and a V6 supercharged holden I must say the punch of the supercharge always put a ;D on my dial when I put my foot down. Maybe the same with these two motors?

[aussiebasser]

I haven't heard of a supercharger failing. It's not an add on, it's an integrated screw type. As I said, it is possible to run the L4 up to 400hp, so at 150 there are very few stresses on the internals. It is a relatively low boost system.

[Noelm]

there is a lot more to the Verado than just "tuning" the ECU to get bigger HP out of it, and the thoughts of 400HP are pretty unrealistic for outboard longevity.

[aussiebasser]

I did mention that it affects reliability in my first post Noel. I removed and replaced the ECU myself for the changes in my motor, the motor never left my garage, but performance certainly changed. I'm told it's like chip mapping in a modern car.

[Knotpretty]

I run a 150 verado and love it. They tell me the new 150's are even better. Once you have black you never go back. KP

[lembo]

yeah I must admit im a Yamaha fan, but hopefully my next boat will have twin 150s on it and I am spoilt for choice 140 Suzuki,150 Yamaha,150 merc. are my 3 of choice. think I would stay clear of the verado. but the 150 merc is sounding very impressive.

Ah yes, but that wouldn't be comparing two motors of the same horsepower.
