Re: performance numbers for 18 and 20 secraft with 150
I used to run a Mercury XR4 2.0L 150 carb'd model on my Seafari. It would get a GPS measured 46.5 knots (53-54 mph) on a good cold day with the top down and just me in it. Loaded up with 4 adults, fishing gear and full fuel dropped it to 41-42 knots at WOT. Cruise with that motor was best at 25-28 mph, which is just slightly more than I cruise now with my 90 hp Optimax
Another 20' SeaCraft owner locally is running a 250 Yamaha HPDI on a Porta-bracket. He claims well over 60 mph at WOT, but I don't remember just how fast at the moment.
