it comes on plane pretty fast. never been in a 28 with less power so not to sure how the boat with a 496 would do. 5 blade prop is awesome on it. i use to run a 28p bravo 4 blade boat came on plane slower and top end was less 68 @4900 on gps. with the 5 blade comes on plane quicker and really lifts the whole boat out of the water more for a better ride and speeds. runs 73 @5100 on gps. thinking about doing the whipple kit on it this winter but questioning reliably if i do it.......

I am impressed with the speed diff from 4 to 5 blade you stated. I keep hearing a 5 blade will cut down on top end. I am at 74 gps with 496 ho with procharger. I am running 28 bravo 1. I tried a bunch of props but I could not get my hands on a 5 blade to try out. Feels like I get a lot of slippage at cruising speeds. Acts like motor is never under a load and you can rev the motor up while cruising without feeling a speed increase. I would love to see upper 70s but I may be kidding myself.

I like the speed increase you saw with the 5 blade too. Was the Bravo 1 labbed or none labbed? Is the 5 blade labbed?

Verbi69,
Haven't been here for a while,just read your post. When my 280 had the HP500 it ran 71-73 gps. I sold the HP and built a 548.Runs 80-81 now. Quite the handful after 78 if the water is not perfect

Hi Bob,
What is your 548 rated at for hp?
What rpm are you spinning your motor at?
Have you ever ran a 5 blade on your 280?
Sorry for all the questions....
I like your speeds

thats a great prop, I HAVE A px5 30 ITS A GOOD BOW LIFTING PROP. Now when this lean happens has anyone tried to chop the throttle and trim out a little. I have seen this on some hulls that are trimmed in all the way and once your on plane you have to trim out a lil and chop the throttle and the hull straightens out.

Hey Verbi, Have you ever kept track of any type of fuel economy on yours? I felt mine was a pig for a single engine boat. I talked to raylar and he stated I would be much better off pulling off my super charger and going with one of his kits. I doubt I would go that route unless something drastic happened, but really seems like they are the way to go.

By the way, The graphics on your boat kick azz.

specialk,
I think that the first time I ran the boat after the Raylar kit I thought "wow- this thing is hard on gas". After thinking about it, it probably seemed to be because I was running all over the lake buzzing the engine at near wide open throttle racing everything in sight like a fat kid in a candy store..... And it also was my first ride of the season with the new setup.
Putting everything in perspective it is no harder on fuel...I would have to say it is easier due to the extra power and torque on hand to propel the boat. It gets on plane quicker which is a big bonus....
I dont think the stock fuel guage is overly acurate either.....and I don't usually worry about fuel consumption too much as a general rule though. - Smiles per gallon is my theory...lol.
For comparison the boat is awesome on fuel compared to my buddies Baja 302 with 454 mags at all cruising speeds and at the higher rpm range....simply no comparison.
The other thing to remember with these 280's is they are a big boat for their length and definately not the lightest either...so it needs power to push them.
In a nutshell I love this Raylar kit.....I only wish I turned it into a 600hp kit as the hull responds well to the added power.
I am a believer!

And thanks for the compliment on the boat...the graphics is what caught my eye initially when I was looking to buy!!

I had a 290 PQ with 502s before this and it was better on fuel. I quess because motors never had to work hard with twins.
How does your 280 ride compared to your buddies 302?
Is the 525 kit all bolt on... or did you have to crack open the motor. I thought the 600 kit required pistons and some other internals but I might be wrong. I was not sure what kind of $$ it was.
