I agree with the others,leave it alone and step up when ready

just sold my 26 after two years good boat but time to go.31 or 358 now.best thing to do is keep it stock sell and go bigger sonic !

Thanks for the info, but that is great for the 496. I have a 502 EFI, any other suggestions? How much should I expect from the reprogrammed module & flame arrestor? Tube Headers vs. stock manifolds? Any experience is appreciated.

What speed is the boat running. I am in the market for a 26 sonic or AT.

67 on gps. I love the boat it rides great but i just want to go faster. I think im just going to sell it. If your interested in a clean low hour boat let me know mine only has 81 hrs and it is stock.

Not sure about the 67 on gps ??? I have a 26' with the 496HO which is roughly 10 hp more and only saw 62.8 gps, and that was 1/2 tank,no equipment,and 1 other on board.

I put a whipple on it,started with 5 lbs of boost changed pulleys and am now at 7 lbs, had problems finding the right prop ended up labbing a 28 bravo1 4 blade.

I now see with this set up 76.3 gps at 5100 rpms which is rougly around 700 hp ?? Not sure I had it dyno'd with the 5 psi,and at 5100 it was 627 hp.....So I am just assuming that 2 more lbs. of boost would give me around 75 hp.

I would say either whipple it, or best bet buy a boat with the speed you desire.
And a true speed of 26' s are around 64 gps. Not what people want to hear, but it is a wave crusher.

When it's rough at 76 I am cruising by the boys that are running in the 80's because there boats do not handle as well.

Mine did 64 on gps with 4 people and 3/4 tank of fuel. 67 with 2 people running right at 1/8.

Those speeds are about right. Fully loaded with the family it's not more than mid 60's on a GPS speedo.

There are lots of bull****ters here on OSO. I bought it because it was a tank.

I have 300 hrs, at 500 it will be a Rayar kit. I want to keep it to 89 octane. I get it wholesale.

I've got a real nice '98 260 factory Merc Racing 525SC, full hyd. steering, K-planes and drive shower. 200 original/one owner hours; on '03 trailer. Very clean boat. 70 mph+ every day.
Eastcoastbrad...I've got two new 31SS' in stock.
