Motor not reaching top speed or power?

[imported_Bman1]

I have a 1995 Johnson 90 hp outboard and the other day I was cursing to my fishing hole and the motor just sort of bogged down (lost power and speed). It runs smooth but just doesn't have the power or speed that it did prior to this. Would like to here your opinoins before getting it serviced. Thanks.

Thinking back, I have had peroids where this happen for a second or two, but regained power immediately.

if running a built in tank, check the vent, also is the primer bulb collapsing, starving for fuel. i have a 88 spl that did this. it was the vent clogged . could also be fuel pump failing. not pumping enough gas for high speed. could be clogged high speed jets.

Or a high speed jet in the carb getting plugged or partially plugged or dropping a coil.

I just experienced this same thing, my carbs needed to be cleaned, carbon deposits were causing bogged down performance. Not a hard process but you may need to be a bit handy.
