I think the three blade prop was OEM, the two blade for racing. Before you try swapping props, make sure the compression nuts on the water tubes are the correct ones. They were not current standard compression nuts that are available today. If the original ones were replaced with common hardware store fittings, there will be an air or water leak in the system and it won’d draw water correctly. If the nuts are brass, they are likely incorrect. This is a very common problem on the ’28 and ’29 Fleetwins, Fastwins, and Speeditwins.
