mirage 23 plus help
 
I have an 88 baja with a bravo 1 and was running a 19 pitch quicksilver. I came across a pretty good deal on a 23 pitch mirage plus from a mid nineties baja which looks to have never been used. This prop has baja performance boats etched into the side and is different from the other prop. How can I tell if its solid hub vs rubber hub? How can I tell if its good to go on the boat? I mean it fits but has a very small gap between drive and prop and doesnt have a large internal hub that runs the length of the hub only one that is 3 inches or so. Any help appreciated

What makes you think you can turn the 23 if your running a 19 now? The mirage plus is a larger diameter and has more cup too. You will likely loose 800-1000 rpms by switching.

What engine do you have and how many rpm's can it turn wide open?

I've got a 454 that has been rebuilt to a 468 with some pretty good parts. Different heads, good sized cam, and 850 Holley carb. I think it's pushing between 450-500hp. I don't know for sure what the wot rpms would be cause I'm kinda scared to rev it too high and I've already spun one prop. I think with the 19 pitch it will rev past 5000 and that scares me so that's another reason I'm trying to drop the rpms a little and hopefully get a higher cruising speed.

its most likely a solid hub,,does the inside of the hub have a twist to it?..put it on and see what happens,,use vary little tab with this prop,when you get the boat on plane trim it high on the gauge to where it almost slips then ease into the throttle..thease props on baja's like a little slip..going from your prop to this one you most likely loose like 5-600 rpm's..

If your HP numbers are accurate then that prop might work well. What drive do you have, Bravo1? If so the Mirage + will work fine.

Mr Maine 08-07-2012 09:00 PM

Ahhh, more power, more prop. Definetly cant hurt to try it, see what rpms it turns wide open.

ckcgobigblue 08-08-2012 10:23 PM

It is a bravo 1 drive and I guess I'll try it out this wknd. Still not sure if it's solid hub but thinking its not. If not could I buy the solid hub kit and convert it if possible?

^^^ Yep no shame in testing out different props...

I also have a 265 that came with a 19p. Only mine has been repowered with a 502 EFI. Food for thought, here is what mine did . With the 19p I could get 52 mph and could rev over 5000. I also got a 23p baja prop from a buddy. With it I get 56-57 mph but can only spin 44-4600 rpms depending on water/load.

ckcgobigblue 08-09-2012 10:38 PM

What hp are you pushing? 415? Im fine with running 4600-4800 rpms cause I feel more safe there. Don't like or wanna run over 5000. Thanks for the input

Lab a Rev 4, I did on almost same setup you guys have an increased 9mph WOT(at 55 now), great accel and no slip as my Mirage's...had many. A great 4 blade and stayed within 4600 rpm. I'll never go back to 3 blades...at least for this boat, the 350 stock..

astar77350 08-13-2012 08:30 PM

Interested in your findings. I have a stock 88 240 with a 454 MAG. Currently running a 23p 4 blade. I'm overall happy with the prop but am looking for a little more top end. I tried a 21p laser II and had a lot of slippage at take off and, like you, was getting to high in the rpms to go to wot. I'm wanting to try a 23p 3 blade, but want to test one out before buying.

I tried the prop out this wknd but didnt get to try it out alot because we were at the lake cumberland raft up all day and we had 6 people and 2 coolers on board as well. Another problem is my speedo doesnt work, im gonna get a handheld gps unit and hope it works well. I can tell that it raised my cruise speed at the same rpm and I ran it a little and got it up to 4600 rpm wot with trimming it a little but like I said that was with alot of weight in the boat. So far I am happy with it but I need to get that handheld gps and try it compared to the 19 pitch I have.

I use my android phones free app called Ulysse Speedometer in its cradle, works great.

Yep, lots of GPS apps out there now, I used GPSspeedo - free download, and I like it because it gives you a large digital readout that is easy to read at speed. Verified it against the digital speedo in my Civic, and it is pretty accurate. Not sure how well it would work on a lake if you are not getting good data coverage, however. Has anyone tried?

ckcgobigblue 08-16-2012 10:37 PM

thats great Id love to use my iphone but lake cumberland has sketchy service and its always edge network. id love to not buy a gps, any info or advice?
