    2004 Honda 150 vtec VST drain location

    Thanks. I certainly hope so because the next step was going to be attempting to pull the VST out and open it up for possible issues. I was happy to see fresh clean fuel when I drained it but I know there still can be a number of other issues inside.

    2004 Honda 150 vtec VST drain location

    Hello. I’m new here but have already gotten great information from older threads. New owner of an old 2001 Proline 19 sport with a 2004 Honda 150 VTEC that I’ve been tuning up. New to boats altogether. When I got the boat the motor fired up beautifully and idles like a million dollars but I’ve...
