Trying to get the best speed out of my 350 MAG MPI/ 21P Mirage Plus Prop
I have a 2006 StarCraft Nexstar 19' boat that weighs in at 2100 w/o engine dry. It has a 350 MAG MPI 300 HP Engine and a Bravo 1 outdrive.
I currently am running a Mirage Plus 21 Pitch prop. The boat goes 58 MPH @ 4750 RPMs with just me on board. My WOT range is 4800-5200 RPM.
Am I lugging the engine at this RPM? Would I gain performance by having my prop "labbed" or changing pitch? Are there any better props out there? I would like to see 60 MPH if possible. Any suggestions? I wish there were easy upgrades for the MPI engine, but I think it is maxed out w/o internal engine work.
Any help is appreciated!!
