hello, i bought this boat a few months ago knowing that it did not run. performed compression test and had 120 psi on all 4. purchased carb kits and installed, installed new fuel pump. removed lower unit and replaced waterpump. put boat in water and it would not run over 2500 rpms. if i choke engine it dies instantly. i tried removing fuel cap in case the tank wasnt venting with no change in performance. checked physical condition of electrical components and insulation was coming off most of the wiring so i decided to replace the stator, trigger, rectifier, all four coils and wires, spark plugs and the switchbox. put boat back into water and still will not run over 2500 rpms. removed powerhead and replaced crank seals, checked exhaust tube for plugging, installed new exhaust gaskets and plate. reinstalled powerhead. boat still will not run over 2500 rpms in gear. i am running out of ideas. please help!
