Murphys Law,Sounds exactly like an Outrage 18 to me. This problem has been discussed before here on the FORUM. While it could well be a clogged vent I suspect it is merely the way you are filling the tank.
I owned a 1983 Outrage 18 and had exactly the same problem you describe. I learned that to fill the tank without a mess the nozzle of the gas pump must be inserted from the inside of the boat. By this I mean the curvature of the nozzle must match the curvature of the filler tube.
By doing so the tip of the nozzle will not hang up on the part of the filler that holds the retaining chain for the filler cap and the fuel ill flow much more easily into the tank.
If I held the nozzle from the outside of the tank as I would naturally do if I were standing at a gas station the gas would back up and splatter all over. I could just turn the nozzle 180° but I found it was much easier to just climb in the boat and sit on the RPS while filling.
I always had paper towels around the filler ready for any spillage that might occur. I never relied on the shutoff on the pump itself but rather made my best estimate of how much fuel should go in the tank and then stopped short of that. Nobody likes having gas spill out the vent while driving down the road even if the gas went into the tank without incident. A very full tank and a hot day can cause an overflow from expansion as well.
If you are careful to fully insert the nozzle with it pointed the correct way, go slowly and do not top off then you will be just fine.
