hey rowdie, i just made the switch last year and am really enjoying it... got a 20' g3 with a blue 90 and added an elite 7, 80# 60" terrova with i pilot on a puck, and some ram rod holders... most toons have either 7/8" or 1 1/4" rails, and you can get rod holder mounts for either and fit fine under my tarp with holders removed... 80# works well for me, but anything bigger, or for fishing current, i would go bigger... it is in the way when not in use, but comes off with 1 pin pulled... the head sits about 2' above the motor base unless it's really rough...
it is different than running a boat, but not alot... i thought i would get blown around bad, but is much better than expected... seems "planted" in the water even in the wind... for example, if you cut power, the bow doesn't spin around in the wind like a boats will... the storage is less than a boat, but the floor space, ride, and stability is incredible... the 90 pushes me about 24 with 2 people, 18 with 4, and trolls down to about 1.5 for pulling cranks...
my attitude about toons has changed 180 degrees... my next boat will be a 22-24 foot triple tube with a minimum of 225 horse with a wot of at least 45...
wish you were closer... would let you run it for a day to see what you think... good luck!!!
