BROKE AN EAR OFF PROP

HEY AL.....PLEASE DON'T USE CAPS AS IT MAKES IT HARDER TO READ AND PLUS IN BLOG LANGUAGE YOU'RE SHOUTING!

Give the guys at Delta Props a call and tell them your a CCFan and they'll hook you up plus give you discount.Might even be able to upgrade your old prop for a new one.

That's a wild ride isn't it. I threw a blade once while I was barefooting and I felt the shaking in the handle at the end of a 100' rope.

Hold out for a few hours there are a few guys here that should have some prop input for that boat, they'll chime in sooner or later.

I say do a search on EBAY under "inboard propellers" and find one. You might save a few dollars for gas money.

I havent played around with the 17' Mustang17/American Skier hull at all... but I bet either the Acme 1210 (12.5x12 3-blade) or the OJ 12x13 3-blade would work well on it. Those are my favorite all-around props for my 302 powered 16.5' Skier.

Then again, if your use of the boat or the environment you run in are extreme (weighting the boat heavily, operating at an extreme altitude, etc) or have extensive engine mods, then something else may work better...

I've thrown blades off two of my props through the years. The first time was on my 64 and it punched a hole in the bottom. That's when I really found out that the bottom needed replacing. When I pulled the engine I discovered the inner keel under the engine was pretty rotten.

Not wanting to go through this again, a friend with a metal inspection service X rayed the second prop. He didn't have anything to reference good or bad so I got a hold of Michagan Wheel. I ended up sending the X ray to one of their engineers who had been with them sometime like 30 years!! I called him after giving him plenty of time to take a look at the X ray and asked him his thoughts. He told me he really didn't have any since this was the first X ray of a prop he had ever seen!!!

My day job (as a Veterinarian) has taught me that we don't have ANYTHING that would generate enough kV to penetrate brass or alloy props with x-rays. Pen clips and staples block medical x-ray beams..... and talk about x-ray scatter! A prop is a definite no-no on the x-ray table. If you find a machine that can actually penetrate it ..... don't stand in the room or even the building while it is taking the radiograph!!

I bet Pete's radiograph of his prop looked like a white prop on a black backround....... and nothing else.......... LOL.

Didn't say they can't be done, just that they are not medical x-rays.....for S's and G's, what is their kV or mAs? Bet it is A LOT higher than what we do........

BTW - keep wearing those lead BVDs!

Sure he should send you a bill..... it probably cost him 50 bucks just to turn that baby on! Image what the maintenance agreement cost for repair is!! Our machines only cost $100,000.00 ...... and there is no way we can penetrate that propeller.

(Keep that in mind when you ask your friend the vet for a radiograph of your pup! LOL!)

I'd love to have a machine with that kind of x-ray power! Talk about a serious CAT SCAN! LOL!

Sounds like an Acme 1210?

Waiting for confirmation first... but maybe.

And you might inherit someone elses junk.. if you are going to drive a boat hard.. like a turn at 50.. at the very least spend the money and know that you have trustworthy running gear. You, passengers, and gear being thrown out of a running boat at 50 as a result of an equipment failure is not something to mess around with.

That very thing just happened in a lake 10 mins away from me. 5 passengers aboard a SN and all thrown out during a hard turn...one death.

truly appriciate the helpful tips from such a knowledgable bunch. boy it makes me feel really stupid not happy and excited about how much more fun this boat has become overnight. while im on a roll of stupidity might as well go all in, what is lapping? the gentleman at delta said just make sure the key is in down position and equally separated from shaft and prop?????? i used a huge brass prop puller that came from my uncles gar wood. im really sorry im not as keen and informed than so many others thats why the questions. if anyone could explain what i did wrong would someone enlighten me so another prop doesnt get ruined if i havent already done so in the 30 mins i put on her yesterday. thanks again for the help and ill try to overcome my incompetance. one doesnt learn if one doesnt ask thanks again

Prop manufacturers can only get the mating surface close to what your strut has and lapping will custom fit them together. For optimum performance and reduced vibration you should lap the prop. Cheap insurance and piece of mind.

The blueing is simply an optional step to show you how far off the bore taper on the prop is off from the shaft taper. You can see how far mine was off in the first Prussian blue picture.
