20HP vs 25HP Outboards

Post by areame »

As it's starting to warm up there have been a lot more outboards for sale and while I still have some money it seems like a good time to get one. I'm building the Squirt and was originally going to go with a 20HP as it seems the most popular but I have also been seeing some 25HP with builders who had beefed up the transom. I was wondering if there was a big weight difference or a power difference between the two motors. I have done some research online and I read some articles saying a 20HP was just a beefed up 15HP and a 25HP was a weaker version of a 30HP. I had also read that the 25HP will maintain speed more when riding with extra weight but would have about the same max speed as the 20HP. I have no idea if any part of those are true but would just like some input on the subject. Thanks for any replies.

Top speed may not change much. But, there may be a big difference when you load up the boat.

Thanks for the reply. I think I'm going to go with the 25HP then, unless I stumble on a good deal for a 20HP, since I will be running with one other person most of the time.

You may want to look at the CC's, bigger is better. More low end and can swing a higher pitch prop with more speed. Now if it is the same CC's it will be a RPM thing.Some time motor builders play with that and port timing.Take a look at the WOT rpm for the motors.Its the hole work over time thing. JMTC
