While vintage motors are what look best on a Feathercraft, there is a reason that two strokes are no longer being made. They are incredibly polluting. A 1997 study concluded that they were by far the greatest source of pollution in US lakes and rivers. They were dumping the equivalent of 15 Exxon Valdez spills into American waters every year. In addition to being quieter, more fuel efficient, and more reliable, modern four strokes are 98 percent cleaner. No one should feel apologetic about running one.
There are several Vagabonds with 4-stroke 25HP Suzuki's on them at our Arrowhead gatherings. I have the same Suzuki on my Deluxe Runabout. I can touch 30 mph in my DR when I'm alone in the boat with everything just right. Under more typical conditions I expect a solid 28 mph from it. I've run alongside one of the Vags for comparison, and we are about neck & neck, so they're getting 27-28 mph from their Vag with the 25 Zuke.
One of the nice side-benefits of a modern motor is that they all have options for digital instrumentation, displaying engine data similar to what's available for a modern car. I see water speed (with an added paddlewheel sensor), RPM, temp, oil pressure, and instantaneous MPG from my motor on a dashboard display.
I find your almost apologetic post for putting a modern 4stroke on your boat familiar, I felt much the same, but having environmental asthma I had no choice if I wanted to enjoy the boat. Took my Honda 25 long shaft off my LUND fishing boat and converted it to short shaft with a seized donor motor. Wanted a bigger motor for the LUND so it worked out well. I believe my boat will run close to 30 MPH but feels faster in my Vagabond 2 with no windshield….

I have a 1956 Vagabond 2 and I am looking for a new Mercury 25 HP... Saw this post!
Exact setup I want to do... What exactly did you order to get the setup you got? I have 2 daughters and we want a setup like this!
Thank you & Respectfully
