I recently purchased a 2000 18' center console sea pro with a Yamaha F115 4 stroke. I'm having issues with is getting out of the hole or up onto a plane (usually takes some time or playing with weight distribution). It also will not get over around 4500 rpm. I had it serviced upon purchase with full fuel system cleaning. I'm going to have the mechanic check the injectors for me again but I'm thinking it may be a prop issue. Anyone have any experience selecting a prop for this boat and outboard combo??
