225 Vmax is over kill and really too much weight. Better suited to a 23'. Even half of that power is sufficient to satisfy a 20 in most cases. Case in point, I think it was bitsamonkey that recently re-powered his 18 with a Suzuki 90 and showed 6.9mpg at 27mph cruise, topping out at 37mph. I have a healthy 115 tower of power on my Seafari 20 and have yet to actually "need" more power.
