For those that own the 20 Outrage Classic with a 150 hp, what kind of WOT speed are you getting?
I'm thinkng of buying one and wondering if 150 is enough or should I go to 200?
I'm looking for a WOT speed of mid 40's, which should give a good cruise at 30-35mph.
Thanks

Are you talking outrage or V 20 ?
I ran a 150 Johnson before this 200 & on the right water she would push 50 real hard but mid 40s was easy.
Your gonna run the 150 harder then the 200 to cruise at 35 & use more fuel.
The 200 will twist more pitch thus more speed at lower rpms.
I would definitly look at the Evinrude FICHT 200 hp,....5+ mpg at 30 mph.

Also, if it takes, say 100 horse to move a V20 at 35 mph, wouldn't it be the same fuel economy? Assuming that you are using the same technology [ficht].

The difference is, the "V" 20 has a much flatter bottom [ less dead rise ].
In order to go 35 mph with a 150 hp, you would need to put the throttle approx 3/4 of the way forward with a 14.25 x 17 prop, or approx 4,500 rpms
Now put a 200 hp on & put a 14.25 x 19 or 21p & you will only need to put the throttle a hair over 1/2 throttle [ 3,500 rpms with the 21p & 4,000 rpms with the 19p ] , - 500-1,000 rpms less then the 150 hp.
It's the rpms that cost the money.
When you go past 4,000 rpms, your fuel economy gos straight down.
The 200 hp will alot less then the 150 hp at 35 mph.
