I did find a vented filler neck that should alleviate the problem.

CB, the vented cap you show...is it somehow vented with the cap on, or does it vent for the purpose of filling the tank only?...
MJ, one thing to consider is gas expansion...when fresh from the pump, it just came outta the ground and is cold...sits in your tank for a while, warms up and expands, finding its way up your vent-line and out. Do you store the boat w/a full tank?...or fill it on the way to the ramp?...if you store full, try not topping it off at the pump...I know you want all you can get in there, but if it's burping it back out, you're losing what you would have left out by not topping up...and you don't pay for what went on the ground...
If you fill on the way to the ramp, you'll probably be burning it off before it has time to warm and expand...
