Thank you for welcoming me to this forum. I recently purchased my first boat. It is a 1991 Chaparral 1900 with an inboard Mercrusier 4.3L V6. I have worked out all the corrosion issues and fuel issues and it starts and idles great. However, there is no top end power. Alone in the boat, it tops other at 3200 rpms and won't plane out very well (large wake). When loaded it won't get past 2600 rpms. I've narrowed it down to a fuel delivery problem, either the carb or the pump. I cleaned the carb screen filter and bought a ln online fuel filter but haven't installed it yet. What are your thoughts. Thanks in advance.
