Mach Sterndriver prop unusual hub! need help
 

I did some trading on some used valvetrain parts for what i was told was a bravo 4 blade. when the prop arrived it was a Mach Sterndriver prop and did not have the usual bravo square bore drop in hub. It came with a hub but it is 1'' propshaft and i have 1.25''. does anyone know what this hub is or if they even make one for 1.25' what are my options?

This thing must be quite the oddity....

Looks like PowerTech.

Thanks I emailed them hopefully hear something. If I can't locate a hub for it do I have any other options that make sense cost wise. Is it possible to weld a solid hub in it that makes sense cost wise vs selling g and buying different

I could be wrong but I thought Powertech hubs had only 2 divertors not 3 and they used a total of 12 cushions. Powertech called it CushionLok hub system. just saying.

Maybe google - images of powertech cushionlok hub system. I would if I could but google search locks my computer up completely and so does Bing.

From what I searched on google and YouTube it didn't look like their hub it had a lot more vision tubes and not as pronounced tabs sticking out

Well It made me wonder to so I pulled this off of www.ptprop.com in which is Powertech's website. Hopefully it is current catalog showing their hub design and just like I remembered their cushion hub system from the PAST.. (2 dividers and 12 cushions).

Click on link below and scroll thru the pages and they show their hub kit first couple of pages down and then again at the last couple of pages.

Powertech emailed back and said it looks like an original mach factory style hub? No clue on where to buy one. Is mach propellers out of business

I knew it was not a powertech hub kit. Try Teague a couple of years ago I think they did but do not know currently. If no luck, wonder if you could get a rubber pressed in hub installed by a propshop Just saying

Whatever you do, don't call the seller and tell'm he ****ed up and to please take the prop back.
