I can get 3-3.5 mpg. HP500 is 87 octane rated but I have my timing up and run 93. Gas is cheap right now, enjoy it while it lasts!
Mine ran best with a 23 mirage
Did 64 with thru hull exhaust.
Change drive oil every year and reveal drive if you find water.
It's about 21' 6". Your trailer will have probably an adjustable winch post anyways. Make sure the bunks are in the right place though. I had a trailer built by Kokopelli in AZ last year and it...
The 600hp blew up in the first hour.
It's an HP500 now. I want to do a -2 drive and I can't get shorter with the King Cobra.
There is no 24p Mirage unless it was labbed. Mirages come in odd numbers. Bravos have 4 blades and handle completely differently. I've run on them on a Donzi, Formula, and Scarab. 4 blades...
I also ran a stock 26 Bravo but there was way too much stern lift.
I like the Bravo I better than the Rev 4 but I ran them with different motors
Didn't like the 24p Rev 4 with 330hp, didn't ride well.
Bravo I labbed 28 was better with 540hp but still gave the...
What's the Prop drive tab set up?
1.43:1 gears for 454 or 460 motors, can work on others with the right prop. Fits 1988-1994 boats. Will be an upgrade for 1988-1990 because those drives have dog clutches and this is the strong cone...
I need a cover too. If your snaps are the original ones on the boat, I'll go in on two with you, maybe it will be cheaper to have two made at once.
If you already have yours, would you mind...
I have a 1992 330hp 454 KC and got 67 best on a Mirage 23 before repower.
My buddy had a 460 KC 1989 and got 65 out of it.
Anyone know of where to order one besides getting one made?
I have a 27P Mirage Plus removable hub Herring labbed for $450. Behaves more like a 25-26 pitch. $400 lab job on it.
The king cobra is decent but its tough to get parts for as in even the impeller isn't made by Omc any more. Tough drive though. I wouldn't buy a running king cobra boat and then pay to convert it. If...
I hated the Rev 4 when I tried a 24p. Held the boat in a way that made it slam into the tiniest wave.
You all need 25 pitch at least. I ran a 23 Mirage + at 4500 with my stock 330hp 454. I cut it down a bit to get it to 4700.
Stock 502 donzis were 75 mph boats and you can do that with either a...
Just because your temp sender on the water pump or intake or whatever doesnt show an over heat doesn't mean your risers are being adequately cooled.
Obviously if you are burning hoses you aren't...
Ya mine does that too. Leans real hard to port at low speed when stopping too fast.
The engine builder is tuning it with me this time. Not sure there is going to be a need for the dyno but I have been thinking about it. The roller cam won't need a break in.
I had a new one built which is approx the same size, maybe an inch longer. What I find by reading Oso is that oil cooler need to be bypassed with a thermostat kit because the oil gets too cold in the...
power is from 1500-6000
I think peak is 5500
I doubt it will because 5500 rpm with a 25 Mirage is 84 mph and I dont have the running gear for that.
Ok so it looks like we are going to a roller cam and hydraulic lifters. The builder recommends Howard lifters. Cam will be ground from a blank I believe.
Also I will put in a this timing set:...
