A 90 HP outboard on a classic Montauk is good for 42-44 MPH (69 KPH). 100 HP is good for about 46 MPH (74 KPH). 115 HP is good for about 50 MPH (80 KPH).
I've driven a Montauk 17 with 115hp 4-stroke, and no problem at all to handle. I would guess a 140 would work just fine.
Howcome the Montauk 17 is "that slow". I used to have a 800 pounds center console v-hull (18 degrees) which made 42 mph with 60hp 2-stroke Mariner alu propeller. It also pulled a 160 pounds water skier out of the water on one ski.
If the Montauk weighs 900 pounds , sholdn't it be capable of at least 46mph with a 90hp?
By the way, I know that boat handles a 140hp 2-stroke.
