Just got a ProBoat Shockwave 26

[Fischetti11358]

Regular lock nut is fine. I'd get a 42, 48 and 51 and try those. On higher voltage it's gonna like the 42. On lower voltage, bigger.

Are you referring to the motor or battery voltage?

I'm putting the props in my shopping cart now. Should I get one bigger than the 51? They have a 54 and 57 also.

What else can I upgrade on the boat? Does anyone make a metal rudder? Are turn fins worth upgrading?

Sorry I must have been confused.

So if I'm only going to be running a 3s, what other sizes should I get besides a 48? Maybe a 51?

Yes and yes.

Here's what happens when you try to go to fast with this hull

Biggest I've tried is a 51. If you can, get an 80 amp proboat esc and run it on 4s with a 42-45mm prop. That's the fastest, most reliable setup. I'd keep everything else as is.

[Fischetti11358]

Ok, so I'll just order the 48 and 51 props.

I don't see the 80 amp ESC on that site. I see the 60 amp is $115. Do you recommend another company for an ESC, or stay with PB?

Proboat. You'll have to buy one used in the for sale section here when one comes up. I'd get the 42mm while your at it. When you get the esc and a 4s pack you'll need the 42mm prop. It'll do around 40mph with that setup

[Fischetti11358]

Do you have a link to the 80 amp ESC, maybe I can find it somewhere else.

What speeds will I be getting on a stock setup with a 3s and either the 48 or 51 prop?

I think my son's does around 30-32mph on 3s with a 51mm

[Fischetti11358]

Nice!

How much of a difference is that over a stock prop?

It did 22mph on the gps, stock on 3s. Like 16mph on 2s lol

[Fischetti11358]

Just ordered the props! My new battery should be here Thursday!

I did a x642 for a customer , he liked it so much he got two more.

FYI: BHCheiftan recommends that size for the IM31's

Jan has CNC'ed M642's FWIW - http://www.kintecracing.com/CNC_Machined_Props.html - have to scroll down aways. - I've been thinkin about getting one to try out on my IM31.

[J.W. Pepper]

Jw, your right. Now that I think of it, it was only the steerable out drive version that had a 1/8 shaft. My bad.

No prob, I was up all night. So I was a bit rough by 6am; took me awhile before it dawned on me why Fischetti11358 was being so adamit about the x435 size.

Last night I was checking out the MG24 for a BL project using a PB1500Kv motor with 90A SK speedo. Part of my research involved trying to figure out what size prop to use with that setup, that's what made me think of it.

[J.W. Pepper]

Yes and yes.

Dude - that's sick!

Have you thought about adding some glass to the interior to stiffen up the hull?? That's my only real complaint about these boats, thin plastic on the sides and especially the top rails, see attached, I drew red lines on them.

I got one of those Bondo kits I posted pix of in this thread (post #9)... http://forums.offshoreelectrics.com/...tion-need-help to reinforce mine.

Now if I could just find time.

I've tried several cnc props on numerous boats. None of them performed near as well as the carbon props and Octura props. I even sharpened and balanced one last weeked. Was the same exact prop as an Octura I had that I s&b.....was noticeably slower. I've officially given up on cnc props. As much as I hoped they would work as well...they dont.

That boat you see in that video, destroyed itself. It could only take so many flips lol. My fix is I bought a 26" fiberglass hull to replace it. I just haven't put it together yet. In that video, it had a castle 1512 2650kv motor running on 4s. It was very fast.
