Re: 33 johnson
Hi ron. I used to have a '66 33hp Johnson myself and I currently run a '66 20hp as well. You've pretty much laid out all of the pros and cons already. While both motors will more or less achieve the same speed, the ease with which they can do it will vary greatly. The 25hp is probably best if you're going to be running fairly light loads (1-2) guys fishing. However, if you plan on carrying heavier loads on a routine basis, you might want to stick with the 33hp which should get up up on plane more easily and allow you to cruise at lower rpm, which may actually save you gas in the long run when compared to running the 25hp at WOT all the time to stay on plane. It's kind of like comparing a Truck to a Sports Car. They can both hit 60mph, but they do so in very different ways.
