Good Morning, Just purchased a 2004 seadoo GTX 155 as a project for the winter , and like to know how to rotate engine to check compression without a ECM or key both were stolen?
I'm not a 4-tec guy but I'm pretty sure you can get the engine to turn over by jumping the two posts on the solenoid, after removing the spark plugs. I'm moving this to the 4-tec PWC section.
