Hi, I have a '87 175 that has no power when in forward gear. will only rev to 2000 rpms. revs up fine out of gear and in rev. ran good going out but lost power coming in so its not bad fuel. also the fuel pump is good. I checked timing advace with ohm meter as per manual and checked out ok. unless I missed something. Any advice would really help it's killing me because it runs great with muffs so I have to put it in the water to work on it.
