    sl1050 running problem?

    I have a 1997 sl1050 put in the water today ran good for about 45seconds then feels like its in limp mode where the computer will not let it run over 2500rpms, the gauge does not work so i put my hand on engine to make sure i was not overheating and the engine was cool. what would cause this? I seperated the electric box and everything look as if it was new. I did pull the plugs and they were wet with fuel, also all cylinders have perfect compression. what should i do?

    Unplug the gauge and try it ,if that doesn't work open the electrical box and remove the grey wire from the board if that works let us know

    And if you do pull the grey wire.........and it DOES work, dont just leave it and call it good. Lugs is just saying that as it will help us identify a possible problem.

    It appears the piston burned up on all the outside edges (is that the piston rings I see in the pictures) ?

    Please post pictures of the heads .I think you might have high compression heads.

    130- 150 psi sounds like too much of a difference,you should also look at the cylinder that has 130

    I bet you have a cracked/ dropped piston skirt.

    Pull the cylinders and see what ya find.


    Edit: well, maybe not yet. But i bet you will find cracks along the intake sides of the pistons either way. Those pix do look like a lean condition started the damage.
