Info on 310 vs 330 motor

Looking at a 01 with the 5.7L 310 motor. Is that still a strong motor or is the 330 a lot better?

The standard TBI engine is perfect in an 01' X-Star, the upgraded motor was called the LTR, my understanding is it is the same block, cam and heads with a different intake and ignition system.

I have the 310 in my 30. It ran decent before with boarding and surfing. I changed out the prop and it runs much better now. I don't feel I'm lacking power, but I've only known the 310.

There's a true hp thread somewhere in here. the 310 is supposed to have a better torque curve. I replaced my 330ltr with a 310 predator because I couldn't find an intake manifold to overhaul the motor that came with my block. Can't go wrong either way I think.

The 310 is plenty. With a 14.25x14.5 prop, mine gets out of the hole no problem with 3000lbs of ballast plus 6 people.

You think that is the best prop set up for running a lot of ballast?

Always contact the mfg for recommendations on props, OJ or ACME both make a hell of a product. How much % of the time do you plan on having the ballast full? I think some folks either overestimate how much boarding they do vs. cruising, or otherwise don't empty their ballast very often.

Mine is the stock prop I got off a buddy's 07 x2. I have no complaints with it. As stated above, getting in touch with the prop manufacturers is the best idea. They will often send you a couple to try out. This thread provides a pretty good overview of some of the options.
