Saw in another thread someone was very close to bumping the rev limiter w/ the stock 24 p B1, just wondering if we end up ordering a new 288, should I ask for a 26 B1 and maybe lab it a bit, and I also heard the 26 was faster at say 4,700 than the 24 at 5,000.

What are you guys w/ 24 B1 and stock H.O.'s running for WOT rpm's ??

what do you think about going w/ the 26 B1.. Thanks Chris..

Wow,, no replies to this question ??

Chris, here are my numbers from a 2002 288. I only owned the boat for a year then bought the 32' so I wouldn't say I optimized the props by any means. All speeds are GPS but under different conditions. All props are bravo 1 4 blades.

Labbed 24 (added cup and thinned blades) 66.2@5100 (occasionally bump the limiter.)

25 (Re-pitched 26, thick blades, borrowed prop so not exactly sure what the specs were just that 25 was stamped in the side but looked like a stock 26 to me) 67.1@4800.

Stock 26 - 69.2@4750. Good air, light on fuel.

Added a 3.5lb Procharger and reprogrammed ECU from Whipple

Stock 30 - 72.3@4600 (way too big)
Stock 28 - 78.1@5050
Labbed 28 - 75.4@5200

Shortly after labbing the 28 I sold the boat so I never really got to work on getting the prop right.

Thanks CCarloss, looks to me like a labbed 26 is the way to go.. I think the other thread I saw confirmed this also..

I'm running the stock 24p that came with it and on a milder day I'm not bumpin' but I'm up there. My speeds a re a little different in that on the average summer day with varying levels of fuel I'm running a solid 68 gps with my best on colds days has been just a couple of tenths over 69 and that's the 496HO. I think my motor is a pretty strong one too when considering the 10% +/- factor on the dyno. I could see though how a 26 would work if labbed, but I always have chose the security of a strong stock prop over the fear of dinging the fragile and expensive lab job...

Hey guys,

this may sound like a dumb question but I would rather ask and know then either wonder or do something wrong.

I got the 288 with the 496HO and stock prop. (4 Blade from Sunsation I believe)

First of all, it sounds like I might hit 70 or at least 68 on GPS???

Secondly, does it hurt the motor if you do hit the rev limiter? I was not even sure if my new motor had one or not.

Thanks Dave

Lucky, yes you should be right around 67-68 with the ocassional 69 in perfect conditions and light load.

Quite honestly I think the labbed 24 hurt my performance but never tried a stock 24 4 blade. I'd say the stock 24 is probably the best all-around prop. Like Chris232 said, a well done labbed 26 in the area of 25" would work well if you are looking for every last mph.

The rev limit on 496HO is 5150RPM. If you touch it occasionally, I wouldn't sweat it. I just wouldn't be running around all day bouncing off it.

Lucky

Thanks for the reply.

First of all it is a family boat, wife and two kids. So all around performance and fuel economy are main concerns.

It is nice to know that if I go out with the guys and do a little racing that I have a rev limiter to save damage to the engine.

Be sure to take into consideration when you prop your boat out the differences in how the boat/motor will perform from spring/fall compared to the more hot & humid mid-summer period. Run it one summer with the stock 24p Bravo you will get; get used to it; then consider making any prop changes...

I don't own a Sunsation, but I went through the same thing with my 28' Nordic with the 496HO. The speeds were basically the same as your boat. I went through the labbing "nightmare" and will never do it again on a mild powered boat of this size. The headaches and expense were not worth it. I used a bunch of props from different companys and the differences were minor. I actually lost speed in my cruise which mattered quite a bit to me. I might have gained a click on the top end, but I was just fooling myself. The boat was not going to hit 70 and I just resigned myself to that fact and went back to the stock 24 Bravo. It had the best cruise, almost best top end, best rpm range, best getting on plane time, etc. If I had it to do over again, I'd just send it out to get balanced and sharpened PERIOD. If I owned a Skater or some monster machine, I can see the benefits, but I'll not go through the hassle again if I wind up with a similar 28' boat again. Save your money and enjoy your boat
