hi i have 2 major issues, i have a maxum 2100 ldr with the 120 hp force L drive and my two issues are i ran the boat twice and the day after the second time i decided to change the plugs and found water on the spark plugs. all four cylinders range between 149-181 psi for compression ???? next i was attempting to install the stingray xr 3 i believe its called and on top of it not working i noticed there was that brown sludgy water/oil coming out of two small holes on either side of the lower unit, so i drained the lower unit and when i took out the drain plug water came out for a good minute and then some and then finally the garbage oil (brown sludginess) started to glob out i am lost now is the lower unit no good now or???
