Default 1800sr3 4.3l 19p prop question

2009 1800sr3 4.3l carb, had a 21p from factory, decided to swap to a 19 pitch for the watersports. now wont reach more then 4500 rpm, thought that if you dropped a pitch rpms go up. is there something wrong here? with the 21 it would hit 4800 easy. thanks

Wow! You're spinnin' that thing hard! I'm surprised that they had a 21 on there when you bought it. 23 has been the factory standard for many years. What does your Mercruiser manual say about max RPM? My manual, a 2006 1800SR-3 with the carbed 4.3 specifically states not to exceed 4400rpm, but when you look online, typically people state that 4400-4800 is the range, but I'll stick with the 'official word'. Actually I've never exceeded 4200 when coming up on plane and then run about 3000 to 3500 when cruising. When pulling an adult wakeboarder I never need to exceed 4000 and then settle down to about 2800 at 19mph with a 23 pitch prop! makes me wonder how accurate the Faria tachs are.
