I have a 2000 champ 203 with a 225 EFI. Motor runs strong and idles awesome. dont know what my motor height is at this time...running a worked 25P tempest plus by mark. last night 3 people in the boat it ran 61 GPS @ 5900 R's-can go more.
anyway, i know i had a ton of weight in the boat, when we went to take off, we had to have both of the guys in the boat go towards the front so that we could get on plane. then once on plane, we took off great and had no bow lift hardly(which sucked).
when we dropped off one guy to get the truck we went and jacked around a little and it still had to have one guy go up front til we took off. irritating...i did notice that i had all three vent plugs in the prop...does that make a huge difference?
