Best propeller extreme cut

Here I cut down an old ski boat prop to make an awesome little race propeller.
Loved turning an old broken prop into an awesome prop which out performs all my other props.
Hope this can inspire 👍

[@25hpboatracerman]

Hi Mate, That’s awesome 👍 yeah playing with props is great fun and especially rewarding when the prop works really well. All the best, Aussie Boat Guy 😎

Good job mate the prop is looking mint. Is there any chance u can do some more outboard video stuff like outboard testing on tinnys thanks cheers mate.

[@25hpboatracerman]

Hi Mate, Thanks 😊 Yep, would love too do some more testing, just really haven’t had many small motors come through for ages. Cheers 🍻 Aussie Boat Guy 😎

[@josephhalwagy6435]

Mate, you are definitely a rare outboard enthusiast and a Central Coast legend. Thank you taking the time to record this clip and sharing it on KZbin.

[@25hpboatracerman]

Glad you enjoyed it Mate, I had so much fun working on that prop and super happy with how it runs. Cheers 🍻 Aussie Boat Guy 😎

[@Diesr]

gday mate im back again with another question: i wanted to prop my 5hp for underwater drive but i dont know what i need to get speed outa it what pitch and diameter i am completely clueless

[@25hpboatracerman]

Hi Mate, For normal running at factory depth the propellers that come on the motors are normally pretty close to what you need. For more speed, make the boat as light as possible and play with your trim settings. Cheers 🍻 Aussie Boat Guy 😎

[@menopiko]

Hello dear, really nice speed, congrats...Could you give me advice which racing prop size good for 6 hp Honda 4 stroke

[@25hpboatracerman]

Hi Mate, Unfortunately I am not sure for the 4 stroke Honda 6hp. it’s really not a motor that would be suited to modifying sadly. Cheers 🍻 Aussie Boat Guy 😎

[@menopiko]

I watched the video where you used 5 hp, ı think it can be same size, maybe...

[@a3_Beats]

Dude i love this content, you truly know How to do stuff with boats and motors, i dont remember if i told you but i for the first time tested my winrace! I bought a winrace cleaver and it was rippin! I have not minutes the steering and a throttle lever but i just used the, Im not really sure of the name of it but the like handle on the Yamaha 9.9 to steer and throttle!

[@25hpboatracerman]

Cheers Champion. I’m so glad you got a winrace cleaver, they are very good props and as you know perform really well. Thanks for your support mate. Cheers 🍻 Aussie Boat Guy 😎

The speed you are getting out of that little outboard is absolutely amazing! Really love the rooster tail too! 😎 Interesting to see that the methods you use to cut, shape and balance props, are exactly how I modify my RC boat props! 😊I even use the exact same "epoxy and stainless dowels" method of securing props with brass bushes to suit smaller diameter shafts. In my experience, it's not a fool-proof method, as there is inherently a tiny amount of run-out with each bushing being applied, and these inaccuracies tend to "add up", sometimes resulting in a wobbly prop. Am I making any sense here? Just one final thought regarding the static balancing of RC props: I have a commercially available aluminium balance-tool-thingy, which also uses 2 conical end pieces to fit the prop snug and true to the shaft. The only difference with my setup compared to your much larger device, is that the shaft has been ground to a very sharp point at both ends. The shaft is supported at each pointy end by rare-earth magnets, which means that there is virtually zero friction when the prop is spun. This setup enables incredibly fine prop balancing. This kind of tool is not only used by RC boaters, but is widely used by RC airplane guys too.

[@25hpboatracerman]

Hi Champion, Yep, your making sense 👍 You definitely need to make sure that the bushes you insert and true and centered for sure. I used the same magnetic balancers with my rc propellers in the past, would love a giant setup like that. Thanks for your comments and input mate. Cheers 🍻 Aussie Boat Guy 😎

[@pietlopsa9164]

Thats so genius!! Thats double the speed I am achieving with my stock Tohatsu 8hp. But she cools herself now under full throttle. I love that motor but the placement of the Thermostat under the head is so stupid. What do you think are the easiest steps to gain more top end speed?

[@25hpboatracerman]

Thanks Mate 👍 Yep, the thermostat under the head is not ideal but glad you sorted your cooling. Easiest speed mod is lighter boat and prop - engine height. Cheers 🍻 Aussie Boat Guy 😎

[@raddeal1]

Well done mate

[@25hpboatracerman]

Thanks Champion 👍 All the best, Aussie Boat Guy 😎

[@besearchingforwisdom6267]

From an 8hp engine, that's amazing! When you balance the prop, did you compare the faces of each blde for equal thrust? I'd think that would be as important as weight balance

[@25hpboatracerman]

Hi Mate, Thanks for your comments. I didn’t change the face of each blade, just put a finish on it so the original shape was maintained. All material was removed from the back of the blades. I did check the pitch of each blade though to make sure the prop was good before starting on the project. I’m super happy with it, it performs better than I could have hoped. Cheers 🥂 Aussie Boat Guy 😎

[@donsscooters]

I'm impressed!! That speed using everything you've built has got to feel great. I love fabing and building good stuff from junk. Thanks. DS

[@25hpboatracerman]

Hi Champion, You and me both! Making stuff from junk is so satisfying. Cheers 🍻 Aussie Boat Guy 😎

[@FlyingZombiekiller]

You are a Legend!! The know how you show us here is phenomenal. I love your videos and can’t wait for the next. Thanks Mate☺️

[@25hpboatracerman]

Wow, Thanks for your supper champ, it means a lot 👍 All the best, Aussie Boat Guy 😎

[@weilfast]

Great job!! Respect the fact it's built not bought.

[@25hpboatracerman]

Hi Mate, Thanks 👍 I had a blast making it and so happy it works so well. Cheers 🍻 Aussie boat Guy 😎

[@motorv8N]

That’s work of art! Subbed!

Welcome Champion. Thanks so much for your comments and support. Cheers 🍻 Aussie Boat Guy 😎

[@simbachka7966]

Привет, дружище! Смотрю твои ролики с огромным удовольствием! Как легко ты модифицируешь любые винты! Поучиться у тебя надо этому)).

[@25hpboatracerman]

Привет, приятель! Спасибо за твои прекрасные комментарии. Спасибо тебе, Aussie Boat Guy 😎

[@Tech_90599]

Super cool. Hats off to the doing it crew. After seeing your mods to aluminium props I have modified three props, what a difference it can make. 🤠 Only problem with the aluminium is how thin you can go at the tips... I think you"ve shown us a great alternative!

[@25hpboatracerman]

Hi Mate, Thanks for your support champion 🙏 So glad that the vids are helping. Cheers 🍻 Aussie Boat Guy 😎

[@Jive86]

Same here mate, ive made all my mates fishing boat motors go up a hole or two. Absolutely magic. 👌
