- In this video I balance a propeller at home using simple tools to show it can be done, it’s not too hard. Take your time and check balance regularly. Also show the painting process I use.
It’s a great way to bring old props back to life or check balance of a prop.
Hope this vid helps.

Hry mate top vid and educational. I did this today and my mercury super 15 original prop was way off. I put in my drill and it was worse than yours. Its now perfectly balanced thanks to another great educational vid of your. Good shit mate.
Hi Mate,
That’s awesome 👏👍
Glad that the video helped and thanks for your comments, I really appreciate the support.
Cheers 🍻

Great video. I was starting from total ignorance and this was so easy to follow and also indicate what bits are important and why. Really nice too that you use the tools and common knowledge that most people have. Cheers!
Great take, gonna give my propeller an overhaul, never thought of balancing the prop, thanks for making me aware and how to “balance”
Too easy mate 👍.
Glad to help.
I have learnt a great deal. God bless you.
Thanks Champion 👍
God bless you too 😊
mate, it was a pleasure watching your clip. I learned from it. Thank you for sharing.
Awesome 👏
Really appreciate your comment mate.
👍👍👍
Great video as always!
Cheers mate 👍.
So funny I came in from outside and I just had two levels up on concrete blocks (was my first idea for balancing my trolling motor prop) and I was looking at videos and came across your video and I was like yes I did something right lol.
You did the right thing champ 👌
Well done mate 😎
Cheers 🍻
Awesome job!
Thanks mate 👌
Really appreciate your comments

very clever another good video mate.
Cheers mate 👍
Really good. What about measuring the prop edge to hub edge on a flat surface for even pitch between blades and possibly banging them to the same measurement?
Y'know I've spent years balancing props on radio controlled airplanes and I never thought to check my boat's prop... good call, thanks for the educational vid. Any suggestions on what to use for a shaft to do this with?
Thanks Champion,
It really doesn’t matter what shaft you use, as long as it is perfectly straight and round plus fits snug inside your prop bush. I made some long cones that slide over a shaft that centre my props on my shaft.
Cheers 🍻

Make sure that the upper side of the levels are smooth. Nice video!
Cheers mate,
Yep, very very good point.
👍👍👍
great informative video
Thanks for the video. Do you think this prop took damage/ leading edge wear that put it out of balance or would it have been this way from the factory?
Hi mate,
I’m not sure what caused that props issues ( probably wear) but I have seen props that bad from factory.
Cheers 🍻

Do you ever cup any of your props? I'm sure you would do a good video, easy for me to understand....nice video.
Cheers mate.
I do cup props but have not needed too for a while.
Next time I will video.
Thanks again 👍
Good job! What make/type of black paint did you use?
I use white knights squirts quick dry gloss. I have tried a lot of paints and found that, although it’s not an expensive paint it really does well.
Cheers
Very good video. My question is how did you attach the spindle to the prop?
Hi mate,
Thanks 😊
I have two cones which push into the hub and that centers the prop, each cone has a spring that pushes against the cone to keep them in the hub.
You can use any straight shaft as long as it is tight in the hub.
Cheers 🍻

helpfull,you say? *very* helpful,thanks;
Cheers mate.
All the best 👍👌
What kind of rod are you using
Could you please do a video on straightening a propeller shaft
Sure, I will have to wait till I have to straighten one though so might be a while.
A slight bend is not that bad to straighten but badly bent I don’t even bother as I worry about the stress and strength after it’s straightened.
Cheers
@@25hpboatracerman I can send you a few bent ones, haha
Is there a functional reason why you paint them, or is it just to make it pretty?
Hi mate,
Painting them protects the aluminum, sone alloy props seem to oxidize pretty fast so paint helps seal them, oh and it makes them pretty 🤩
cheers 🍻
Aussie Boat Guy 😎
Just wondering what you used to match your rod to the prop bore? Thanks
Hi champion,
I have a number of different shafts, some old outboard drive shafts, some that have been turned that fit snug in a number of propellers.
The ones that done fit snug I have a shaft with two sharply shaped cones that slide onto the shaft and press into the hub centering the prop.
Cheers 🍻

If it’s stainless, is there any benefit to painting it? Could it just be left shiny bare metal?
Hi mate,
No benefits to painting a stainless prop. Only time painting would be beneficial is an anti-foul if it lives in the water.
Cheers 🍻

Hello i was wondering if you know what colour the 2 stroke tohy cowlings are thank you
It’s a specific Tohatsu colour. The black is actually a really very dark blue.
There was a few shades of grey they used over the years too.
I have not found an off the shelf colour to match unfortunately.
why even paint the prop? its aluminium right? wouldnt rust anyways or whats the benefit?
Hi Mate,
Will not rust but will oxidize in the salt water.
Painting the alloy props is worthwhile, I do polish some alloy but they need constant polishing, basically after an outing.
Cheers 🍻

Where can I get a shaft little fit that prop to balance it Bob Elkhart where did you get your shaft at
Hi mate,
Honestly you just need a straight shaft that fits right through your prop.
Think mine is an old driveshaft or something
Cheers 🍻
Aussie Boat Guy
What if shaft is a little bit bent?
Hi mate,
The shaft needs to be very straight.
If the shaft is even slightly bent the propeller will not be balanced.
Cheers 🍻

@@25hpboatracerman Hi! Thanks for the reply!
That means, the balancing wont work and I can just throw everything in garbage :D
Probably I can still save the propeller, but the shaft needs to be replaced first.
Thanks!
polish it. clear it! ha
Hi mate 👋
Yep, polished a lot of my special props 👌 don’t need to clear coat, it end up chipping and peeling. I just give them a quick polish every now and then.
Cheers 🍻

I thought that you were😢 supposed to check that all the pitches were the same too. So you said you sand down not the pressures side. Can you just say to sand down the part that faces the front or the part facing the rear. Thank you. That way people can number the blades before they take it off. I thought the pressure side was the back of the prop so I checked. Material removed from towards the tip of the prop will have more of an effect on the balance. Remove material with a file from the front of the blade ONLY, i.e. the convex side which is the same side as the drive dog slot.
Hi Mate,
You can check the pitches for sure with a bevel if you are at home.
Thank you for pointing out some extra things I could have added to the video.
I do clearly show which side to sand though. With props it is either pressure side or low pressure side of the blades.
Hope it was helpful anyway.
Cheers

@@25hpboatracerman Professionals have curved blocks with the pitches and can see if any blades are bent. Every step is important for the best results. I did enjoy watching your video. You seem to be a perfectionist just do not want you to miss a step. You keep saying do not touch the high pressure side that seems to be the back of the blade and the front of the blade appears to be curved which you can adjust. Are you supposed to check if those curves are the same too or is that going to far. Lol. I guess you can just get a brand new prop and make a mold of the pitch and the outside curves. I heard of motors from Yamaha coming with some no name propellers and when a Yamaha propeller was used it worked a lot better. Wonder what the difference is between a good and bad prop. From trial and error you must know how to shape it to get the best results I will watch your video again
@@tommytriglav5181
Yeah, true I would love a set of pitch blocks.
I do however check the blades with bevels and gauges before I start, I will add that into the next video I do on props.
Cheers 🍻

@@25hpboatracerman I was looking at the sharrow prop and to me it looks like two three blades narrow props at a different height to give 6 total blades. Can you make one like that? No need to connect the ends. Call it the Aussie prop. Market it and sell it could make a lot of money. It could be like a 3 blade prop with the center part cut out and then maybe the pitch of the remaining blades changed. That would probably be the easiest way to make one. What do you think. That way you could get regular cheap props cut out the center part then charge a lot lol
@@tommytriglav5181
Hi mate,
Yeah those sharrow props are pretty cool.
I have thought about that principle (even years before the sharrow appeared)
I could not cut the centre of a stock prop though, the blades need to be offset in the flow of water to catch the low and high pressure water coming off the first set of blades.
I am always thinking props though, waiting for another revelation to hit me 🤷♂️

What kind of rod are you using
Any straight rod is fine, I often use an old drive shaft or a bright rolled solid bar.
Cheers 🍻
Thanks
