Mercury 4 stroke 30 HP
I wonder if any of the experienced of you can help me out?
I have a 5 metre GRP fishing boat with a 4 stroke Mercury 30. The prop is stamped with '13'
Flat out with two big blokes & fishing gear/twin fuel tanks etc it will do 18.5 knots on the chartplotter, but it's only pulling 4500 rpm.
The motor is fully serviced & runs sweet.
Would a change of prop yield any more speed (allowing the motor to achieve it's peak power rpm of 5400?
Sorry it's not RIB related but I'm hoping the knowledge carries across?
Any advice gratefully recieved.
