Anyone know where to buy one of those's prop seals so you can use a small hub prop on a large hub gear case (to seal the exhaust).

ummm, you have to have left out a lot of info on what you are looking for because AFAIK you can NEVER seal off the exhaust, the exhaust has to come out somewhere.

are you talking about an over the prop rather then thru it style propeller?

He is referring to a prop who's hub doesn't match the gear case.He wants to seal the space between the hub and the gear case so the exhaust doesn't leak out and foul the prop.
I don't think there is such a thing.If the hub doesn't fit the gear case its the wrong prop.

There is, IDK if they are sold anywhere. My prop guy has them for his props, but I was hoping to find one for a Trophy and Laser II. Its just a ring that fits around the small hub prop to make it larger before you install the prop and seals the exhaust off from going around the small prop. Like Steelespike said

ok so its an adapter to resize and redirect the exhaust so it doesn't actually seal it off. now I understand.

looks like GA_Boater has you a link for it
