I crawled into & over my engine and measured as much of the fan as possible so I can get a quote for a nylon replacement.
Just thought I would post the worksheet for anyone else with the same engine that is wanting to have the old fiberglass fan "retired".
sorry, fan is 24" in diameter (line 10). blades are pitched 42 degrees (as close as I could measure).
Fan blades are 4" away from radiator. Shroud is 24.5"diameter.
Blades front edges are about 4" ahead of hub and 2" behind hub.
