Hi, I've recently bought mercury 175 v6 which is a non runner, was told "It simply needs the carbs cleaning" yeah right, I'm the dumb one for believing it ! anyway, I've done a few checks, it has a good spark and getting fuel ok but not even a chance of firing, even sprayed a bit of fuel down throats and still nowt, have just done a compression check and theres nothing on all 6 pots, the engine tutrns over by han easily also, the previous owner has also bypassed the thermostats which may tell of an overheating problem, can any one confirm that if the engine has overhetatede and ran for a while would it have burnt the rings and or ruined the bores ? thank you for taking time to read this
Davey
