Just bought a 2005 130 sport with a Mercury 40hp four stroke efi. Pretty disappointed in its power with 2 adults and 2 kids. I suspect the prop needs to be changed but im new to boating so?

At full throttle off the line it struggles to plane and when it does it max’s out at 4500-4600rpm, not sure of mph but guessing low 20’s? I feel it’s worth mentioning the boat is at 5100 ft elevation as well.

Current prop. Black Mercury 10-3/8 14 pitch. Out drive is 2.00 x 1

Any suggestions?
