We had a 115 Merc on ours, great for pulling up skiers.

A few years back, I put a 115hp Evinrude FICHT on my 1985 Montauk. Boat was fast, too fast. Hydraulic steering was a must due to chine walk and swinging a 25 pitch prop at the river, I had 67mph on the GPS. Maybe an inch of hull in the water at WOT, that was it. I wouldn't recommend going over the 100hp manufacturer recommended hp.

I repowered a 1974 17 montauk II with a brand new 115 Johnson in the early 90's (It was origionally powered with a 115!). It was a great combination, and just as stable at speed as my friends with a 90hp's. I see the boat to this day, and the new owner still says it is an excellent set up. I would not hesitate to repower with any 4 cylinder 2 stroke.

67mph, not possible with a 115hp on any Montauk, not even on a 15 footer. Finnigan (Larry) has a 115hp 6 cylinder Merc on his Montauk, and I'm sure his won't anywhere near that fast, and he could squeeze the last mph out of any boat. Maybe he will chime in.

Ours would only do in the low 50's. That was on the boat's speedo (pre GPS).

It's possible, I did it. See what Larry says. You can always calc it. Very low slip #. I believe RPM was 6,100-6,200ish, banging on the limiter. Takes the right prop and a light boat.

Sorry ShadBurke, I have to call BS on your claim of 67 MPH. It would take almost 200 HP to get a Montauk to 67 MPH, except on a trailer on the freeway.
A 115 HP could be good for well over 50 MPH but not 60. I know the FICHTs were hot motors, but not that hot!
There used to be a Menemsha here in Seattle with a 175 HP Johnson V-6. It was rumored that boat could touch 60 MPH.

Down in Texas where they race 16 ft. trihulls with 135-140 OMC outboards they can run in the low '60's.
They would all use 17ft, Whalers if they could run 67 with a 115.

Have read the 120 is about 20% heavier than the 90, approximately 360 vs. 300 pounds. Something to consider if true.

From the old brochures I have checked from 1961 (75hp) - 1975(85-135hp), all the OMC V4 outboards were similar weights 224-267lbs, The difference is the trim and tilt that some motors had or didn't have. What years were the 90 and 120hp versions made.

Stick with a two stroke 90 ,small , light and 40 plus mph is fast enough for a 17

Ok all you speed freaks and doubters. Just remember. there is a max hp on a capacity plate for a reason. Must importantly is to keep all you motor heads and I( dont care about anybody els on the water in check.

I have a 1979 140 hp merc tower of power on my Montauk of the same year. This is a great combination for me. My reason for doing this was i purchased the 140 hp to rob the power trim parts to put on the 90 hp of the same year. I looked at it and just changed out the motors instead because it looked faster. The two motors share the same weight and cowlings. Used responsibly it is a great combination. I am aware of the implied risks of running over the recommended horsepower. With modern bass boats running 300 hp and some jet skis running up to 240 hp this does not seem to out of whack under modern standards. The boat probably goes slightly over 50 mph before it reaches max hull speed and begins to chine walk. It is not the set up for the unsupervised 15 year old kid but non of these boats are. it is really fun in bigger rolling seas. Lots of fun due to the throttle response.
