Spun Prop Hub Help

[pabloescobedo96]

I spun my prop hub over the weekend so I got a new aluminum prop as it was way cheaper than stainless, and I was in a hurry to get back on the river. Well 2 minutes after I launched the boat I barely knicked a rock at an idle and it broke one of the prop blades off. Vibration from hell after that. Aluminum props are worthless!
I've used my stanless prop as a wood chipper, rock smasher, and sand blaster, and haven't had a single issue in 3 years of HARD river fishing.

But now to the point of my post.

I am just curious how hard it is to press in a new hub. I have a killer press at my work and am pretty sure I can get her done unless I'm missing something. Anyone done this before succesfully?

You usually don't press in a new hub. You take the old hub out, put a new rubber bushing in, and press the old hub right back in. If you could get the right rubber, then I think you'd be OK.

sorry I guess im confused. I am talking about the rubber bushing. That is what spun. I want to put in a new one in. Sorry for my lack of knowlege. And where do I get a rubber?

Re: Spun Prop Hub Help

You can press in a new hub to refurbish your old prop, you may need to fabricate a support for the prop out of some old tubing or bar stock machined to fit. you may find it cheaper to just purchase the hub and take it to a machine shop for the small nominal charge.

You haven't posted the type of prop or OB/IB type so I can't give you a part # to order but they are readily available from nearly every mfg.

Here's a list from an Australian site, they just happen to list many different types available. If you have a FloTorq Merc hub you can do the replacement without a press easily.

If you can press out the hub from the new prop without damaging it, you can use it on the old one--IF they are the same. Otherwise buy a new hub and rubber--not cheap, 35 bucks or more. (The rubber donut is bonded permanently to the inner bronze hub)

Use an appropriate sized bearing cup as a taper to compress the rubber and guide it into the prop hub. Slather the rubber, bearing cup, and inside of the prop with plenty of black RTV silicone to lubricate and help glue it. I use a six ton press with no problems. Messy, but it works.

Not to be a party pooper but silicone sealant stays slippery and can spin later on once the rubber hardens up, I have found contact cement on the hub insert with some contact cement thinner as a lubricant on the hub to work better on the industrial props I have worked on. Many times we had used just straight thinner to slide them in with excellent durability.

Re: Spun Prop Hub Help

What a piece of cake. Pushed the hub out of my NEW broken alum. prop. Pushed it in my old stainless bulletproof prop with no problems. I used vulcanizing rubber cement that we use on tire repairs where I work and it worked as a lube while pushing it in and hopefully now its dried and will help hold it in there snug. Of course it does take a press but I needed no bearing cup or any million ton press or anything. Im good to go!!!
