Hi!
I have some issue with fuel delivery to my rxdi 2003. I have read all threads I could find and tested the fuel pressure which passed the test in the manual (27psi when lanyard attached and 107psi when starting it up , also when revving) when not in water. Cylinder compression is 140psi in front and 150psi in rear.
But when in water it wont rev over 3500-4000rpm and you have to increase the throttle slowly.
So I tried the fuel pressure in water and it clearly looses pressure down to like 88psi when I push the throttle.
Trying to pick up som speed:
Giving it fast full throttle several times:
Spark plugs look like this:
Is it the fuel pump even though it passed the test in the manual? Is the pressure drop enough to make such a difference? Or could it be the air compressor?
Thanks in advance!
