Almost all putt putt boats have 2 outlet pipes, but Rob of Brisbane Australia found a rare, single pipe design. I wondered if filling the boiler could be a problem, but Rob wrote,
“I fill the boiler by inserting a length of small diameter nylex tubing down inside the outlet tube, and then run water into the metal tube. The inner nylex then acts as an air release bleeder tube and the boiler fills up. The first expulsions of water and steam seem to push out whatever is excess, and the remainder commences to pulse in the usual Put-put manner. “
Rob replaced the missing cabin and repaired the leaky boiler. We would both like to know more about singe-pipe pop pops!
