I have a '97 2530 w/ 5.7L I/O and a deep vee. Not the same as all the guys with outboards. I cruise at 25-27 mph at ~3600 rpm. I can get down to 18-20 mph on plane at times. I get there, but I don't like the low rpm there (~3000 rpm) so I don't do it unless I have to. I run at three speeds typically. No wake speeds or just above, 22 mph range for rough weather, and cruising or faster. I've had it on plane at ~16 mph at times but it takes work. Have done it for places that have 10 mph limit, like Cape Cod Canal. I'll run at minimal plane then drop the speed off to not get the authorities after me. I think for this style boat, the weight, and the shape, it is asking a lot to plane at low speed. I see other types of boats go by me at 10-12 mph on plane, but they are narrower. For outboard owners, you can play with props. Duoprop owners can as well, but it isn't as important. Changing trim tabs takes some effort as well. I've found running at the slowest possible plane of about 16 mph requires some trim tab, some trimming of the outdrive and constant throttle control to match the waves and feel the boat gaining/losing its plane. Too much trim tab down has hindered it, as well as too much outdrive trimmed down. Shudders the boat too much. I see guys in other boats go by on slow plane all the time in other manufacturers, and I know I can't do it, so I try to avoid slow areas, or I settle for 6-7 mph non-plane speeds. But then most of the time when I cruise at 25-27 mph very few boats end up passing me over a long distance, as they are up and down in speed more. Big boats, long, narrow center consoles, and guys that want to pound their boat go by, usual nobody else.
