    Compression Check 1975, 850

    I'm back ! Told you so ! I now have the engine rewired, carbs & fuel pump rebuilt. Going to drop the lower unit to change impeller since I know it's been over 10 years of sitting (only used three times in ten years). The engine is on a stand and I want to check the compression while the lower...

    So what's the difference with Champion LV series spark plugs?

    Still working on the new to me 1975, 850. Have the timing/belt thing done. OK, my question. Going thru my repair manual I find that 1973-75 Merc 850"s used three different spark plugs. L76V, UL77V and L78V. What gives with that? They all have the same Type III ignition, same timing specs (idle...

    1975 850 Type III Ignition Spark Plugs

    Good afternoon, I am bringing a old 850 back to life to install on my pontoon. My Setech manual calls for Champion L76V spark plugs. It has L78V plugs installed and they are sooting looking with an oil film on them. Thinking it was running rich, so am going thru the carbs and then check timing...

    Is this Mercury considered a long shaft?

    Looking at another engine for my pontoon. Mercury 850 s/n 4294375, don't see any letters after s/n on the engine block, thinking it's a 1975 model. Measuring from the bottom of the engine cowl to center line of prop shaft is 28 inches. Anyone know the weight of this engine? Thanks, Tom

    650 (1963) Water Pump Questions

    Since I've figured out my idle problem, thought it was time for a new water pump/impeller, since it hasn't been changed for several years. The thing has a OEM pump housing (I think) made of aluminium and has a seal in the upper half. The new pump housing doesn't have the seal. (see photos)...

    This engine is new to ME. I don't think it has the correct spark plug wire set. Someone has installed MotorCraft carbon fiber wires. Am I correct thinking this is wrong and should have stranded coper wires, such as Packard 440?
