Well? Watcha end up with?
I would post that I have a 30" setback bracket and a 250 Opti (same weight as the 225 Opti) and I am stern heavy, only on a 20' Wellcraft. I came over here looking for someone that has hung some additional bouyancy on the stern because of this very thing.. Found Hermco here. What a bracket.. Of course Big Shrimpin's bracket, Awesome. What a boat these Seacrafts are. I am a fan, sorry for the derail, weary from walking uphill in my 20 all the time. You may be able to compensate some by putting some additional weight in the nose. Irregardless, it will sit bow proud and look cool. If I could find a reliable/efficient 300 hp that weighed around 425lbs I would be happy, Temporarily...
Post up a pic so we can drool a little.
