ouch, looks like it's through the gelcoat and into the fiberglass. How did the blade break off?

no clue.

Was riding, fell. Drive came to pull me back up, and the boat made an awful noise and the drive stopped and shut it off. I went to check for weeds or something and notices it was missing a blade =(

Is that a crack or defect on the other blade?

The broken blade looks like it had a crack in it quite a while before the break. What brand of prop?

agarabaghi
11-01-2011, 03:10 PM
OJ 14x14.25

It was a prop used to pull the pwt and I got it from a friend. I've put 400 hours on it since April / may....

I would expected ding or bent areas if I had hit something. Not sure when that crack began as the boat sits in the water a lot.

Exactly my thoughts. The weathering on the broken one appears to be long term.

Notice no prop guard on the trailer, any chance damage blades may have hit while on the trailer at some point. Looking at the one blade gone, and one looking like it's ready to let go as well there must have been something at some point. Next thought, has it been rebuilt previously?

agarabaghi
11-01-2011, 03:15 PM
Never rebuilt. We never really trailer the boat so I doubt that. The trailer has a prop guard if by prop guard you mean the horizontal bar close to ground that would scrape before the prop?

Exactly what I meant. Couldn't see it in the picture, must be the angle. How bad is the glass? That sucks. I've been there, but we knew we hit something under the surface, just never could figure out what.

My buddy's X15 lost a blade at about 350hrs, OE OJ 13.7x17. At least his launched into the bootom of the lake and not the bottom of the boat.
Same story, didn't hit anything, never been rebuilt, just a bad prop.

Had the same thing happen to my prop a few years back. It happens from time to time. Fortunately, my blade went the other way (down) instead of into the hull. I have also heard of one instance where the blade stuck in the hull after separating from the rest of the prop.

A friend had a big Cigarette boat (Miami Vice boat) throw a blade, went right thru the hull and engine cover. The cyclical loading of the propeller work hardens the material where it is connected at the hub, eventually it breaks if not inspected for cracks and removed. I had a prop that had some porosity in that area and Eric at OJ replaced it for a new prop free of charge - Thank you agian Eric!

I have seen this (similar) once previously several years back. The owner never determined a cause for the accident. Shaft was not bent, strut was fine, etc... No evidence of hitting anything. His only conclusion for resolution was that the prop failed and one of the blades gave way and hit the hull. The rest of the prop was written off to cyclic failure / fatigue / or malfunction...

Never good to see this but as long as nothing else is damaged, it looks like you got off easy, all things considered. The hull can be fixed easily enough and a new prop. Just make sure there is no other damage,,,,

great stuff...sorry for the damage...but something to remember before backing down the ramp...

Since inspecting the prop is on my pre-launch list, this makes me want to do so more religiously.

Sorry for your loss. Hopefully there is not more to it than what can be seen.

When you look at the first photo you can see the point the prop started to fail, the pin sized mark inside the beach marks. Probably a casting flaw or gass pocket. This is the area inside the dis-colored area near the top. Then the stress of use causes what are called beach marks with are the half round areas moving out from this point, each line is a small crack. They are a different color than the rest of the failed prop since they have ben exposed to water, air, and movement for a longer period of time than the rest of the break. Then you see the clean break which looks granular where the rest of the casting gave way all at once.

Well hopefully nothing is bent, shaft etc...

We did have to idle back to the dock, and then from the dock to the ramp... maybe about 15mins at idle speed on the damaged prop... hopefully they didnt cause any extra damage.

Does your boat sit in salt water, or a marina most of the time? It looks like you have a lot of pitting on your underwater gear, picture of the hull bottom also made it look like there was some hull rash from the prop tip being too close to the hull.

agarabaghi
11-02-2011, 09:56 AM
She sits in lake water all day everyday

Pulled once every few weeks and washed down. But I haven't taken her out in about a month to clean her up.

Pitting? Is that the bumpy stuff on the brass?

agarabaghi
11-02-2011, 09:57 AM
Im not sure i see the rash you are talking about?

Those stress cracks by the underwater bracket holding the shafter (sorry i dont know the name) were there from when we got the boat.

You in fresh, salt or brackish? Either way, you might want to throw a zinc on the shaft... it looks like your dock might be a little hot and is slowly eating your running gear.

Good lesson for all of us. Pre / post season, pull the prop and throughly inspect.

I think I am going to throw mine in the X-ray at work and check for voiding or cracks.

HAHA RIGHT..... or should have stayed in when the winds were gusting at 15+ mph...

Fresh.

I will have to look at the add on zinc, my dad suggested it, where would these attach?

MIskier

The picture that shows the gouge in the gel it looks like there is roughness in the gel which would indicate a prop clearence issue, but it may just be the photo.

You definetly have an issue with something where you have the boat docked if youre sitting in fresh water and your running gear is pitted like that. Adding zinc anodes to the shaft, and rudder will help cure the problem.

I was told by a prop dealer that this is a problem with OJ props ? what brand is this prop ?

agarabaghi
11-02-2011, 03:21 PM
OJ... i believe it a similar crack to what gave out on the other blade...

I will def look into that. Maybe some jack *** kid dropped a battery into the lake haha

It looks as if the crack on the blade (in the picture) travels all the way through the blade.... Looks as if there is light coming through the crack and you can almost see through it! My question is what would cause such cracks in BOTH blades (assuming the one that flew off had the same problem)???

Their customer service is outstanding! Ref one of your earlier responses, it appears you mailed the prop to them around 1 Nov; 2-3 days to get there, another day or so to examine the prop based on their work load, you should be close to getting a response. Call or send them an email, they are great to work with...mac

This one of the reason's I take my prop off every winter. So I can inspect the prop. It is part of my winterizing list. The other reason is so the prop nut does not take a set.
