Changed primary filters and changed low and high pressure filters 50 hrs ago. Boat is a 282 mako with twin 225 Honda's. While running up to plane off the strb motor starts bogging down then back up repeatably at 3000 rpm. When motoring up to that point it is fine. Will idle all day. It feels like it is shutting the fuel off and on. The motor keeps stalling and trying to recover in quick on/off senerio. I checked all the filters again except the high speed filter and everything looks OK. Checked for fuel line issues and found none, all clear. Anything under 3000 RPM it's fine. Any ideas? Thanks
