Motor Troubleshooting
 

Suzuki 75 HP starts fine but only gets up to ~2500 RPM in gear, won't plane out the boat. In neutral will go up to 5500-6000 RPM. Any ideas?
Changed gas and flushed the carbs good with power tune - no help. Thanks for any advice.

Sounds like trash in the high speed jet. Had the same problem with my Yamaha.

Prob need to soakem a couple hrs, come get my bucket of chem dip.

Had a 115 suzuki that did this and didn't realize it has 2 fuel filters on motor itself, one is plastic (easy to change) the other is metal and is behind the intake manifold (NOT easy to change). Hope this helps, fixed my problem.

Change the plugs as well. I had a similar problem on a 115 and changing the plugs solved it.
