  • nissan 4 stroke 25 hp cuts out runs rough

    I have a 25 hp NSF25B with about 100 hours on it, it always ran great in the past, but this weekend I took it out and it ran great for a while, then at full throttle, it bogged down and would barely run at idle, I limped it back to the ramp and checked the fuel filter and tank but no problems, I only run Ethynol free fuel so I,m stumped. The fishing is hot right now so I'm hoping to get back in the water asap. if anyone has some good suggestions I'm all ears.

    Verify oil level. Drain the vapor separator. Check plugs.

      Thanks pvanv, that seemed to do the trick, I'll know for sure tomorrow when I put it in the water, it ran well with the hose connected
