WOT is 4400-4800RPM (5.0 Mercruiser) yet I am only at about 3300 RPM with a 14.5 in 19? pitch 3 blade aluminum mercruiser prop.
I also put manual trim tabs on the boat (which can be adjusted up more). R12-13x14.5 (?) Rule of thumb I read is ~1? less pitch adds ~200 RPM - this doesn't seem right - - to get 1200-1400 more RPM 6-7 ? less pitch -
Thank you for any help.
