Make sure you get the prop hub that has the big bolt axially down
center, not the one with two bolts that are cross-drilled through

As for improving the Onan installation, the single biggest
improvement you
could make would be to do the cooling system properly. The Onan
wants to be
cooled from the exhaust valve side which means that to do it right
need to get the cold air to the back side of the engine and have it
forward. Just copy the stock Onan cooling shroud (in aluminum or
glass) and
get the air flowing in the right direction.... You could have the
outlet(s) on top of the cowl a la Catbird or Adam 500....

I am looking for a propeller hub for my Onan Performer P-224
conversion. It has a straight 1 7/16" shaft with a 3/8" key.
I am also trying to collect any information, pictures,
tricks, to improve the Onan as an aircraft engine. Any help
will be greatly appreciated.
