22' speed runs
 
Made some speed passed with my boat today, and with the non-mag 454, with a Bravo I, Imco Thumper Exhaust, 23 Mirage+, MSD Ignition, Holley Carb I ran 62 at 4600rpm with quarter tank of gas and just me.

Anybody else running similar setups? Does anyone have a 21 Mirage+? Do you think I'll pick up a few by sizing down?

Thankshttp://www.aggrocreative.com/images/scarabdriveway.jpg

I have a 21 Mirage plus that I would sell, not sure it is the right prop for you though. Had a friend with a similar setup, and it seems that the best prop is somewhere between the 21 and the 23.

gumbya55 07-05-2012 07:31 AM

Do you remember if he was running the 21 or 23? I might try to find one to try first, but what do you want for your 21?

rchevelle71 07-05-2012 09:00 AM

He kept switching from 21 to 23, can't remeber which one was faster, but he liked one for speed, the other for handling, one of his may have been a 4 blade, it was a few years, and many beers ago. I would take $300 plus shipping for the 21 mirage plus.

Man, I love the look of your boat, any other pics you can post up? Are your vent covers custom?

I've got a stock 350 mag and I'm spinning a 21 Mirage (Non+) at 4800. I think the + is a little steeper, so it might be a good choice for you.

Yea, my father created those in fiberglass, painted to match the boat. Took some time and alot of work, but really happy with the end result. They have scoops built in to force more air in the engine compartment.

Thanks rchevelle. Im going to see if I can located one to try first...

Do you know what a rev limiter is , a stock 330 is set to 4850, A differnt blade will not make that much of a differnce , A 23 mirage plus is a good blade , a 25 might get a little more but harder to get on plane BEEN THERE DONE THAT have fun

I have a 1998 stock carb'd 454 with a 25p Mirage. I'm only turning around 4,500 RPM, trimmed up, and my max speed is 58. This is with a quarter tank of gas and only me. Thinking about ditching the anchor and the cooler plus run the fuel down to get a true top speed. I hope to put a 23p on this weekend to get my RPMs up. I should be in the 60's is how I feel about it.

I have a 97 22 with a 454/b1 combo. Run a 25p 3 blade turbo. Full of fuel I run 66 on gps in fresh water. On salt I run right at 70.

is that a stock motor set up?

Lets see the interior, year of hull ?
Only reason I ask is because I had a early model 22 which I thought was just a odd duck with no swim platform like yours. Turns out after I parted with it. It was a 21 which was laid up in kevlar? Got pix still, but can't post em up until I re up my membership

Anyways it had 525 & danced a c hair above 80

I assume it's stock?

gumbya55 08-06-2012 07:43 PM

Here's my 22 with a stock 454. Running a 23 Mirage plus: This past weekend...

You're way over trimmed IMO

gumbya55 08-09-2012 09:46 AM

Why would you say that? I think I've messed around with it enough to know where it needs to be. I trim it until I get to about 4700. That's where it runs best...

That sounds very similar to my setup. Don't have the stern jack though. I did install some Imco Thunder exhaust and removed the silent choice. Saw another 1-2mph with that. And I'm running a 23 Mirage+. Havent messed with timing, it runs really nice now and I think that is it for the boat...
