strong vibration???

[Samuelp63]

From what i've seen it's $100-$200 to have one repaired. acme does repairs.

New one is $500. I always keep a spare on the boat... not really sure why, we don't run long distances and i don't keep anymore than a pair of pliers and a couple screw drivers on the boat

I do and would think everybody should at least have one nearby if you boat close to home.
It could ruin a trip without one. You will need a prop changing kit also. I think they call it a weekend saver kit.

I don’t carry a prop but my lake is super deep and I never go close to shore. If I were on a shallow unknown lake I would totally pick one up.

Are these props that fragile? I, no one on board, felt or heard anything.

No, not really, if you ding a propeller you probably would notice. My guess is that the ding on the prop was there when you bought it and didn't notice until now. That one would be pretty inexpensive to have it repaired.

I only had one prop until I accidentally used it as a depth finder on a Sunday morning of a long weekend. I didn't have a spare. Lucky for me I got a hold of a buddy who was home and had one for me to borrow. I had family in from out of town and it would of been an absolutely horrible situation. Now I have 3. Its a good idea to have a spare in your truck just in case. You wont need it until you REALLY need it. Usually you can find used props on here or craigslist/kijiji for a decent deal.

Do you know anybody with a direct drive or v drive that would let you borrow a prop to help you trouble shoot the problem. If you switch the prop and the vibration is still there you know you should be looking elsewhere.

I had a prop get dinged up MUCH worse than that. I could barely notice the vibration. We ended up running it the rest of the season. I felt the prop hit a gravel bar and knew right away what I had done. The ding marks were on the very tips of each blade. Seems weird that you don't know how it happened and that you didn't feel the vibration before your last trip. It also seems weird that the ding marks are in the center of the blades.

When I took a prop from my z3 to get repaired, they said the further toward the hub, the harder to properly rebalance. This time of the year with water levels rising there is a lot of debris, floating branches mainly, in the water. All the stuff that got washed ashore last year is finding its way back in. They are hard to spot at speed.

Not sure your current ballast, elevation, engine or prop, but you may end up wanting a different pitch from what you are currently running now, so it may make sense to buy new. Like mentioned above, see if you can borrow a prop to narrow down your issue. IMO that prop is hammered, not necessarily the dings, but the overall out of balance the blades probably are now. Bummer but probably an easy fix, just more money ha.

IMO that prop is hammered.

So that is a very bad set of "dings" ?

[MJO21]

Is there a way to hook a hose up tot he engine so I can run it in the driveway and see it the vibration is there when the rpms go up?? (in neutral)

[Ryanmorgan1984]

They aren’t bad dings. I’ve seen people run props with little chunks and cuts in the metal, but more outside toward the top of the blade. I was told the vibration is much more from the overall out of balance of the individual blades. You can hook a fake a lake up to the boat, which is a plunger and your garden hose basically, to run the boat out of the water, but to be able to see the prop out of balance probably won’t work. I don’t think you are supposed to run the boat in gear with a fake a lake, and the out of balance is probably very small, like millimeters if you were to set the prop on a totally flat surface. Dangerous to get that close, bad for the shaft seals spinning out of the water, and too small to see.

Out of water I was hoping to eliminate the thought of there being a bad plug, plug wire/coil, distributor....

[Ryanmorgan1984]

Ah, I get ya now. Sorry about that.

Here is what I use when I run my boat out of water on the trailer.

You can diagnose some of this on a fake lake in neutral but it can be hard to track misses down without a load on the motor (prop moving water). Not impossible though, just some issues wont reall rear their ugly head on a fake a lake

[NICKYPOO]

Those are pretty bad. Bad enough to knock a blade out of alignment. I’m surprised you didn’t feel it. I’ve only had one prop repaired. It was a bad experience. In all fairness, there’s only one guy in my town does it and he is a douche bag. Never again. If it were me, I’d send that one to acme for repair and order a new one at the same time. Keep the repaired one for a spare.
