Propeller issue

[Bowler Bob]

I managed to misjudge the trim driving onto the trailer and the propeller hit ground on the concrete boat ramp. I will replace the propeller at some stage, but will I still be able to get around without any huge issues in the meantime with the damage?? Not worried about losing any speed, but will it be actually dangerous because of possible vibration or the like?

Cheers

I had a similar chunk missing out of a prop a few years back and was told by my mechanic that I risked gearbox damage due to the out of balance if I kept using it. I didn't feel any vibration but decided a new prop was a cheaper option than a gearbox rebuild.

Replace or repair before you use it further.  Not worth the risk of damage to the gear box.

It will be OK to use for a while, but...get it welded (will be done in no time) and made the right shape again, use it, then keep as a spare. A new propellor should be in stock at any dealer.

Good advice nolem, a spare prop never goes astray!

You can JB weld small areas quite successfully if you want to save money.

JB weld will last about 2 minutes in that application.

Shame you are so far away. I could repair that damage quiet easily.

Well i do speak from experience. I did mine in a similar area (the damage was a bit smaller). Still there after 18 months and i run at full throttle most of the time.

Maybe they should make propellers out of JB weld? It does work, but it's a "patch" not a repair, spent over 40 years trying to remove "glue" from things so they can be repaired properly, especially Silicon......it's a curse! But to each their own.

Well they do - sort of. Composite propellers are not dissimilar. I'm only talking about minor damage - around 5 cent piece size or smaller. I don't see any downside in such cases. A propeller specialist will charge $150 as a starting point - a bit over the top.

I might go into the propellor repair business if I can get $1590. for about an hours work! A new Aluminium propellor (as this one is)  is nowhere near that price, even from the dearest dealer, but anyway, it's not worth debating, there is options, repair it, replace it, patch it, only the owner can decide which way to go.

Typo, obviously - $150.

I`d get it welded up, it wouldn`t take very long to weld and shouldn`t  cost too much. Once welded it would be okay to use until you can get another prop and then keep this one for a spare

I think that might have already been suggested!

Yamaha aluminium props are very cheap, not worth getting it repaired when you can get a new one for around $120.
