I have a 1988 Chapparal 2350 SX with a 350 CI I/O Mercruiser that seems to have a difficult time coming up on and staying on plane when the throttle is below 4000 RPM. I changed the prop from a 20 pitch ti 16 and that didn't give a noticeable difference. The boat seems to take too much throttle and time getting up on plane and. again, staying there without much throttle. Any advice? Thanks in advance.
