Bogging at mid level rpm range

[krmcgaha]

I have a 2000 model ficht 150 that idles great, runs great on the upper end, but has a slight hesitation, or bogging, at about 1500-2000 rpms. It doesnt matter if it is under a load or on the water hose w/ muffs, it does the same thing either way. When i start to take off, it does fine till it hits about 1500 rpm, then i have to get on the throttle more to push it through that hesitation/bogging, but once its through it motor runs great. It almost feels like its being starved of fuel momentarily until i give it more throttle, and it only does it in that lower rpm range. Any ideas or troubleshooting suggestions would be greatly appreciated.

Have it checked with computer diagnostic and see if TPS is working properly or if has any fault codes.
