Have a 2002 190 ProVee, Merc 200 carb,10" jackplate, 25 tempest plus. Best I can get out of it is 68 with one person, half tanks of gas, tackle on board. Have tried raising and lowering jackplate from top to bottom. Seems to run best about 1" below. Can anyone tell me what top speed I should expect? Have had the boat for 8 yrs. and had given up trying. At wide open throttle boat handles a little wild too, but that's only at about 65-68. Mercury even replaced the power head when it was new, but this didn't help any at all.
Are the 200 carb Mercs just plain slow?
