I would, the FB page is pretty good place for learning about the boat or looking for one for sale.

Update, after trying a bunch of props my best so far is 70.4 @6,1xx with a Bravo FS24 that has had cup and 2P added to it. I was doing 69.4 @6,4xx before I added 2p and some more cup. Any thoughts? Been told maybe try a 23P Enertia eco or a 25P Bravo 1. Maybe a 24P Max5 I feel like now I am leaving 300RPM on the table. Original goal was 70mph but off course now I think 72-74 is possible.

Did you ever try a ProMax?

I tried a ProMax 25P without a ring and was tough getting on plane. Only saw 66.1mph @6,150rpm.

All in under 1 minute of WOT. I think the boat will run close to 75 with this prop once the motor is completely broken in and provided I have a few miles to let it climb. I may cancel my backordered B1FS 24p for now.

Maybe try a 23?

I might do that since my buddy that had the 25P got a 23P

Why not lab that 24 some more to get those rpms? I'm hearing these Rs like to run at top rpm

Will ask Rich who has been doing my prop work about it. I tried a Bravo 1 26P yesterday and it was too much prop. Going to try a Enertia Eco 23P next week along with the Promax 23P.

Do you have a Concept 30 with twin 300R?? If so what props you running?

I do, 26 Bravo 1 FS stock for now. Playing with engine height then they are going off to FJ Propeller.

What speeds and RPM are you seeing? You going to have them labbed or what you doing to them?

So far the best I've seen is 76.8 at 6400ish. I have 2 sets of 26s and they spin different rpms. I'm playing with engine height this year, going up, and.hoping that I will need 27s or have my 26s up pitched or add cup. Either way once I get the height right I'll be sending my props to FJ to see if they can give me a little more.

What props? FS? I raised my motor up two holes on the jack plate.

**Trimmed Out15** · 05-08-2021, 09:53 AM

Yes both sets are Bravo 1 FS. I wish I had jackplates, Concept wouldn't put them on for me. So i have to do it the hard way

**Toffen** · 05-09-2021, 08:57 AM

Hi!

Best prop for me on my 400R (using the same HD Sportmaser case) has been Max5 with good margin. An option is the new bigger diameter REV4

Cheeers, Toffen

**Boats&Taxes** · 05-09-2021, 11:35 AM

I would love to try a Max5, just can't justify buying one not knowing if it will work. I have heard good things about the prop. I have tried 7 props so far, have three more I am trying on Thursday. I need to get some props sold before I buy anymore. I tried a Rev4 and it didn't do much for me. Not sure if it was a the bigger diameter one.
