1986 150hp to mudhole

[sven]

im thinking about going out to the mudhole from atlantic highlands, nj. I would only go when projected weather would call for 2'-4 seas and extended nice weather. Boat is 23 years old but the yamaha 150 runs great and I've already had it out in 5-6 footers right off sandy hook with no problem. I believe the west end of the mudhole is about 12-15 or so miles offshore. I plan to take 10-15 extra gallons gas just in case (have 60 gallon tank). I have radio, gps and of course all other required safety equipment. Anyone have experience taking their 20 footer to the mudhole? any advice is much appreciated.
