115HP 4-Stroke EFI Performance

[lofirehold]

I am trying to get more out of my outboard on a Crestliner 1750 SportFish, have changed to stainless prop at various pitches and can get max 5000 RPMS and 40 m/h. More than two in the boat and I can barely get it out of the water, very slow to plane. Is a performance chip available for this outboard? Any suggestions from the experienced outboard owners?

Sounds like you have too much pitch. I had a 17 Crestliner Serenity with the same motor. It came with a with a 19P SS which performed similar to yours. I changed to a 17" SS which brought RPM up to 6000 and speed up about 45-46 MPH. The 4-strokes are happier when propped to the upper end of the band.
