Yamaha outboard fuel tank

I purchased a 20 hp yamaha outboard for my 14 ft fishing boat. The EPA designed fuel tank is a disaster. The venting of tank is horrible. During the recent hot spell the tank would blow up like a balloon eventually causing a major fuel leak where the fuel line connects to the tank. Smelly and dangerous to say the least. I spoke with the local dealer who shared my frustration. Yamaha solution is to remove the tank from the boat after every use. I dont know if this is unique to Yamaha but I just drilled a small hole through the gas cap to vent the tank, safer than a boat full of gas. Good job epa
