My guess would be around 25-28 mph.

My 22' with a 90 hp 4 stroke gets 25 with 2 on board. You should see a little more depending on your weight, I'd say 24 to 28 mph!

Hi, I have a 20' Bennington with a 90hp Mercury 2 stroke, 2 people on board I can get 23-25 depending on how calm the water is

OK just checking if I was doing the same as everyone else and I can do 24 with just me and 23 with the family onboard.

Two toons, whole family on board, calm water, 23 mph. I usually cruise at about 18-20 mph at about 4500 rpm. This is with a 90 hp 4-stroke Suzuki.

My 22' Sweetwater with 60HP Yamaha 4 Stroke tops out a little over 19 mph spinning 5800 RPMs. That's with the family on board, and I might hit 20 mph under perfect conditions. At 4200 RPMs I run about 14 mph; that seems to be the most comfortable cruising speed.

I got a new 20' with 90hp.

I get 27-28 mph (GPS) with 2 heavy adults. WOT = 5500 RPM Redline = 6000.

The speedo says 30. But I believe the GPS...

I have a 60hp Big Foot and I get 23-24 GPS WOT with 2 people.

I would guess your gonna get upper 20's with a 90

I have the same setup and do about the same as Lunker. I just don't run WOT very much. It sounds better on the motor to me at ~4400 and that is still 18-19. Fuel economy is better too.

I have a 22' with a 90 4st, 27" toons, and got 27.3 GPS with 3 on board and 1/2 tank. You should do better than I do.

Greg F what prop do you have on your 60. I have a 20' Lowe Suncruiser with a Merc 4stroke 60.....I max out at about 17-18 GPS @5300 rpm. Not sure what prop i have now, but i dinged it up a little at the end of last year and am going to replace it soon.


Same question for Lunker also....what prop? (Although mine is not a bigfoot)
