Engine Serial number 0G981368
2000 Mercury Promax 225
Not sure on exact make or pitch of prop, it is a stainless 4 blade with no markings on the barrel, it does have four holes and EOT-14326-R4 marked inside the barrel.
Maximum RPM is unknown at the time because I haven't learned how to drive the boat at WOT and I'm still setting up engine height. At 60 MPH the chine walk starts and I'm still learning to correct it. The RPM is around 5000 at this point.
Idle water pressure is 4-5 PSI and at 5000 RPM it is around 18, unknown what it will be at when at full WOT as mentioned above.
Analog instrumentation installed in the dash.
No engine mods that I'm aware of, but some things aren't adding up.
The boat is a 1993 Bullet 20XD that I bought used a few months ago.
While checking for loose wires under the cowling of my engine this afternoon I found a fuel leak coming from a valve on the bottom of my VST that has been rather crudely plugged off by the previous owner. I have no idea what the valve is for, but I suspect it is a remnant from the oil injection system that has also been removed by a previous owner. Can anyone look at the photos below and advise what I'm dealing with and what a proper way to remedy this would be?
