Thank you very much for your responses... this is what I was talking about.

If that is the route you want to go that is fine. The motor runs about 1100 rpms changing from 30mm to 35mm with the same pitch will yield a 1 mile per hour gain. A lot of work for a gain that you may not notice.
I went four blade for more pushing power as some of the boats I rescued get vegetation rapped around the strut.

Nope, I was just showing you the picture. I will order the Esc you suggested and use the stock motor for now. What size is your 4 blade and which 55T you got? I look around and there are a bunch. Is it the same thing anyone?

[Newboater]

Motor was Novak Rock star 55T which is rebuildable. 4 blade was Dumas 174-03a 35mm m3 shaft.

The Factory motor is closer to 65T a 55t Motor will run the same speed on 2s vs 3s. Try and get a 30-32mm 4 blade, my prop was Dumas 174-03A, but you need to cut the drive dog into it and cut it down in size. Brass is pretty soft so you can use factory prop as a guide and just use a small file.

Thank you very much, you have been very helpful!

No problem, any other questions feel free to ask. The Aquacraft tugs are excellent boats

Hey Newboater I got a question for you regarding the props. I find 2:

147-04A 35mm, M3, Left, 4 blade:

And also: 174-04A Same specs 35MM. M3, Left, 4 blades:

What's the difference? Pitch?

Thanks

[Newboater]

I believe they are the same prop as they are both the same seller and same description.

[chemanuel]

Newboater Somehow the first link show the same prop... the correct link for 147-04 is this:

https://www.ebay.com/itm/Brass-35mm-4-Blade-Propeller-Left-Hand-M3-For-Billing-Boats-Or-Dumas-147-12A/111640733400?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

looking at both of them now, they are not the same. I think the first number has to do with the "shape" of the blades. If you look closer they are different. Now the question is, Which one is better?

Prop on the right seems to have less surface area by using a narrower blade, not sure what the pitch is on either, but probably similar pitch to stock.

[chemanuel]

Thanks... then Would it be better the one with more surface area?

Take the one with the thinner blade just incase you need to make it smaller it will be easier to cut down. Try it stock and see how the boat runs.

Thanks!

Looking to upgrade mine as it’s a touch to slow and reverse is a joke trying to stop it lol .. someone said the stock motor is only 1100rpm ? That’s about a 90turm ??? Zippkitts sells a outrunner for their tugs now .. anobody try a 5 blade prop yet ? Also where can I get a 3mm shaft with threads on the end as mine I’m sure is bent some
