    Help - just bought on a whim a 1980 (maybe) Mercury 175 hp - need help on release of the clam shell cowl and cant find a serial number to verify it

    If the control box uses the 12 pin connecter its a 1976 or 77 model. If running and looks decent might get $1000

    Thats a 2 liter 175. Dont expect it to to perform like your 1990 model. It will perform like a newer150Xr4, as it only has about 155hp at prop.

    Most you will ever see is about 105-108psi at cranking speed. These motors will never see 120psi+ at cranking. Most motors read 95-105psi

    More of a velocity pop than knock , sort like a hand slapping on end of empty paper towel roll. Pull air box,start on hose see if noise is coming from throttle plates

    Tried Everything on New (to me) Boat-1996 Sea Ray F16

    The CDI stator wont work as wrong one. Your motor has CDM modules and uses a red stator. First check compression as these are bad about blowning head gaskets . Also sync and link must be dead on or it wont start, also engine must be in good mechanical state.

    1988 Merc 115 inline 6-Rough in low gear only after WOT

    Sounds like a float is sticking and flooding a couple cylinders. Trimming it up and bouncing back home unsticks it and engine runs fine.

    Mercury Black Max outboard 175hp, Snapped Gear Shifter Top Shift which connects to the lower gear unit.

    Take cables loose, take a roll pin punch and drive out pin holding shaft in shifter yoke, weld and replace.

    All looper motors since1992 has this 1/8" hole right at the exhaust port. It is a idle relief port and drops compression about 10psi at idle. Compression will build back at speed. Us performance guys tap and plug it with a allen screw and then stake aluminum around it to prevent it from backing...

    They never made a low compression motor..just low compression heads. Powerhead is mechanically the same between commercial and recreational motors. Also no covers to remove for inspection

    If you use NGK the correct ones are BPZ8HS-10 and Champion is QL78YC. Which 3 plugs are not firing as motor has a ignition cutout switch?

    Please help.Motor keeps locking???

    The Merosil block does NOT like to run hot as it starts to shed silica which scores the cylinders. If you lugged engine while pulling boat you could have damaged cylinders or lost a exhaust plate gasket, which would allow water in cylinder and hydrolock it. Either is bad
