    thanks Jzelt, i think after all i've read i'm reassured that i won't lack power or stop at every gas station, in the end what i save on gas with a 5.7 will only lead to accelerated wear and tear on the block.

    cheers,

    I had a supra rider with a 440 not I have a malibu 247 with the 8.1 and the motor is awesome and works great for the boat, I really dont find it too much of a pig on a day at the river probably 3-5 hours of riding I go through about $125 that was surfing and wake boarding with full ballast and 10-12 people and sometimes wedge.

    I really don't find it that much worse than my old boat, and I have a 90 gal tank so when i do a weekend on the lake I never have to buy gas on the lake and pay and extra $1 plus a gallon

    as far as props the boat came with a acme 537 13.5x16 the motor never had a problem spinning that prop but it did not pull out real fast loaded up now I have a acme 1273 14.5x14.25 150 cup and it pulls great and still runs about 45mph

    What prop are you running?

    I have the 340 in the 24 and I don't feel like it is tough to get on plane. I regularly have over 2k in ballast and 8 people in the boat without any issues. Prop is the Acme 1433, which was an upgrade to the factory wakeboard prop that came on the boat.

    When I was looking, I ruled out the 325. I was indifferent between the 340 and the 8.1.

    Just for fuel consumption reference, I calculated over 3 tanks of fuel this summer an average of 3.7 gph. That's a 99 ish GT-40, 310hp, with my 21' Bravura, nice new acme prop, 1.23:1 transmission. Always with people in the boat (from 2 people to 12), sometimes ballast, sometimes pulling riders, some idling, some 35mph all over the lake. Anyway it's a reference point, 3.7gph.

    Its a perfect reference point. I don't track mine though. Id put money on mine being higher than that, though, without a doubt.

    We have an '06 with the 8.1 and OJ 466 prop and have averaged 6.87 GPH from March 2011 to present day. We are closer to 6 GPH now cause we dropped 600 lbs to 2600 lbs and speed to 23.7 MPH at 75', RPM's are right around 3000. Overall it's a great boat. We've put 350+ hrs on ours since 2/10 with 1 minor issue. Hope this helps. Good luck with the purchase.

    I have an 07 22 SSV with the 340cat.
    I run the 1235 Acme which is similar to the Acme 1433 mentioned above but a bit larger diameter so i believe it should get better hole shot.

    But with 2500 lbs in ballast with say 5 people it feels really doggish. It can get on plane but is sure working.

    I've had occasion when weve had around 2000 lbs in the rear and everyone in the main cabin (6 people), no one up front and around 500lbs upfront and it took quite a while to get on plane.

    I would suggest if you typically use alot of ballast to go with the larger engine. This is tough when looking used sometimes and cant get the deal when you want.

    I would shy away from the 22 or 24 with the 325 however.

    I had an earlier generation 22 hull (2005) - with the 325hp and the same acme 1235 prop and even with 2500lbs had no probs getting upto speed.
