I thought the same thing.....for $12K you could get the Raylar BCK-103 (With Heads)....have the work done at about any shop of your choice and be close to getting Dana headers.....might be closer to $14K. But that route your at ~550 HP.....175 more than now.

Hey
I love it! Let's start a new engine shop and have a "numbered" menu just like a fast food restaurant.
Call it "Pick Two".
Uh, yeah I'd like cheap and fast please. Okay, That'll be $3200 plus another 15K after it blows up. Please pull around to the next window....
LOL!!

Even the labbed prop may get you no gain depending on what you are running now. The first thing that netted me a real performance gain was the Imco -2" shorty lower and the four blade (yes, labbed by Brett) prop that it required. That gave me 3 mph. Are you able to do your own work? A cam swap isn't that hard. You don't have to pull the engine if you are willing to cut a small hole in the front of the engine room and put a patch over it. I'm not sure what has to be done to the ECU. This will get you about 3 mph. Nothing comes cheap. Sometimes I wish I had stuck with outboards. You should be able to do the cam, ECU, prop and shorty (if right for your boat) for under $5,000 and pick up about 5 mph. I think that is money well spent.

The very first thing to do is aquire an accurate means of seeing "real" engine speeds (if you haven't already).
That nice livorsi tach on your dash is not accurate enough for propping based on my experience.

The Velocity 260 comes from the factory with a Labbed 26p Bravo Prop. I bought a Hydromotive Quad 4 for mine and noticed a 1-2 mph gain on top end, but lost cruiing efficency with the family loaded in the boat.... And seemed to pick up a nasty chine walk Around 65. I went back to the stock Bravo prop that was supplied by Velocity. Just some experience from a Velocity 260 owner w/496 mag....
If your 260 doesn't have trim tabs, that is where I would spend the money. It made a complete difference in my boat as I was able to maintain higher speeds without having to back it down becasue it was flying out of the water....

Very True, my Tach shows to be about 300 rpm off at idle. We verified this by having it hocked up to a diagonistic computer while at idle. Who knows how much it is off up higher in the Revs.

I added tabs a couple years ago and I have a labbed 28 from the factory as well as a labbed 26 (I believe) I tried on it, the 28 is excellent and I have seen high 60's with the boat in this configuration. I was just tossing some ideas around, and know with the HO in a test this boat ran upper 70's. I would just like to be able to break that 70 mark regularly... and by low budget I was figuring $1000-$2000.... Thanks for all the replies
