Just repowered my 1973 19'4" Whaler with a 115 Yamaha 4 stroke.With a 19" Yamaha prop and a good load -3 men and 35 gallons of gas I got 38 mph WOT 5800rpm.As per Gps.
The motor is a screamer.It goes way beyond my expectations.I laugh at the gas pumps now.It appears I use at least a third less gas.
I replaced a 115 hp Evinrude 2 stroke and will never look back.
The Yamaha prop gives the hull great bowlift.

Wow. I have the same boat (1975) and have a 150 Johnson (1990). It is really fast (upper 40's) @ 5400 RPMs but gets about 2~2.5 MPG. I bet you get twice the gas mileage I get. Don't you love these older hulls. I would like to see the modern 19 ft. BW (if there is one) go 38 MPH on a single 115 HP engine.

This is a true story.The first time at the ramp,taking the boat out of the water I had to stop the retrieval of the boat.I could not remember if I had shut the motor off.I had to walk to the end of the ramp to see if it was really off.The motor is that quiet.

Most of us don't have to listen; we just look for the blue cloud...

Yes, there are advantages to a 4-stroke.
