Any Rev4 equivalent props?
I'm gonna try out my 23P Rev4 on the 21Super, but I already know it will be underpitched for that boat. If it likes it, I'd probably need somthing bigger than the 25P they come in.
Figured I'd ask if there are any other props that are = to the Rev4?

I'm turning a 27P Mirage+ somwhere around 5800 rpm and running a best of 85.7 with it right now. When I open it up I really just watch what the boat is doing and take quick glances at the tach.. still getting confortable with this one. I really don't want to turn over 5800 and I know that the Rev 4s act like bigger props than the mirages... the 25 Rev 4 might just work if this thing likes the 23..
If I remember right the previous owner was runnin a QIV he had worked.. but he had to send it back in a few times to get it right.
On edit: I'm just looking to try and improve handling some and keep those top end #s. The Rev4 worked great on the 24SB, so I figure I'd give it a try on the 21 and see how it likes an overall lifting prop vs the bow lifters.

Maybe a bravo will work on the 21.. my 24 hated it.
I guess I'll try that Rev 4 and go from there... if it likes it, I'll try a bravo to compare em on this hull.

I am thinking that your boat probably doesn't need a lot of bow lift with all that weight in the back of a fairly short hull. I would try a Q IV. If the hull likes the prop they can be tuned some for better performance. I ran a Mirage plus on my boat and saw a best of 90 and it was kind of squirrely. It is much more stable with the QIV and top end is better as well.

Gonna bring this one back up:
I swear I came across rumors of Mercury coming out with a couple versions of taller pitch Rev 4 props??? Can't seem to find the thread now (don't know where I saw it)
Looks like I'm going to be adding more power to my 24 and am going to have to figure out what works in taller pitched props.
I think the QIV is about the same prop as a Bravo??? Maybe they can work it so its more neutral like the Rev 4... or possibly adding cup to the bravo would help to make it handle like the Rev 4. I need to call BBlades...

The QIVX is more like a Bravo.
On my boat the Rev 4 & the QIV had nearly the same slip #’s across the board. The QIV did spin less RPMs so you may want to try a smaller pith QIV to keep your RPMS up.
