Yamaha 115HP 1990

[ScottMcNulty]

My motor seems to loose power while I'm moving above 20MPH. It bogs down then comes back again, almost like it floods itself. I could be going any speed, as long as it's above about 20MPH, it does it. Any ideas?

Normal cause is a fuel restriction. can be from a clogged filter, fuel pump or carbs.

main fuse on that motor wont affect running, look for fuel issues. bad pump,clogged carbs or lack of feed from the tank.
lose the speed and give some RPM numbers. speed is absolutly irrelavent and boat speedo's , in my opinion, should be against the law.
its meaningless.
