Hi fellow GW forum members!,
I just bought a 1988 Tournament 19 with a 2003 150hp Johnson that runs fine but above about 3000rpms after several minutes
the "check engine" alarm sounds and lights indicating a fuel restriction. Slowing makes the alarm go off.
The tank is the original aluminum and the entire fuel system will be replaced during the off season.
The tank was also recently filled.
There is no water separation filter on this boat, the hose goes directly from motor to tank.
The primer bulb on the hose looks like it's been replaced by a quicksilver model and clamped with SS hose clamps.
Previous owner had ALL work done by a reputable marina so I'm assuming for now that they replaced the primer with one of adequate capacity.
The primer bulb isn't collapsing but there is some squishyness to it after being pumped full after an alarm.
Yesterday I removed the filter at the VRO pump, took it home and after it dried out I dumped maybe a
quarter of a teaspoon of particulate out of it that looked like orange sand (rust?)
Then I blew out the filter with compressed air and reinstalled it.
Motor ran at 4500 rpms for about 15 mins (which was a great improvement) but then I got the check engine alarm again.
It was dark so I didn't remove the filter again yet to check if it sucked up more of this material.
My research indicates other causes may be pick-up screen and anti-siphon valve.
I'm betting since there was so much junk in the VRO filter that the pick-up screens (if this tank has them)
should be checked and cleared but I might not bother on such an old system
Can anyone tell me if my GW has an anti-siphon valve and where I might look?
Where can I get an OMC fuel line of the correct capacity for a 150hp (2 stroke)?
All the lines I see look like the standard small outboard types.
ANy other thoughts appreciated.
