We're going on owning our 1995 325 Aft Cabin for 2 complete years now, and one thing has always bugged me. Our normal cruising speed is about 10 mph. The specs say this is about HALF what it should be. I've never been able to get it up on a plane. I've tried adjusting the trim tabs to different angles with no effect. The bottom paint was new when we got her, and it was repainted last year. She's got Crusader 350 xl's, one of which was replaced last year, when the old one threw a rod, and there's no power difference between the new and old.

RPM-wise, if I run at around 2800, we'll go around 9 mph. Boosting it to about 3200, we'll only break 10-11 mph. Going above that, it's still just fractionally faster. We'll only get up a bit beyond that amount when we've got very favorable currents. Again, Carver's spec sheet says that we should be doing about 25 mph at 3200.

Are there any thoughts on what could cause the difference between the posted cruising/max speeds and what we're actually experiencing? The only other thing I can think of is that a previous owner replaced the props with something a lot smaller than original. But as it'll probably be a while before we pull her out again to check, any thoughts on other things to test/tinker with in the meantime?
