Like stated above, definately a looper. It could either be a 2L or 2.5L in a 175HP MERC. IIRC a 2L should have around 100 pounds of compression, and a 2.5L FEESHIN motor should have around 120-130(my XRI has 128). I personally junked the oil injection system on my 95 150 MERC 2.5L. Read to many stories of the nylon crank gear breaking. Or even worse it starts to strip the gear and the pump slows down, but not enough to set the alarm off. When I removed mine the metal gear that rode against the nylon crank gear was worn to the point it was razor sharp(I could have shaved with it). Also look under the flywheel to see if the magnets are loose. And if you run it, don't freak out when it doesn't shoot water out the piss hole right away. The MERC system only pees when the T-stats are open.
