    How reliable is 50 hp 4 cyl 2s? Versus an I-6 90hp?

    I have a chance to pick up an early 80's model that has good compression and seems to run ok. What type of problems do these motors tend to have? Of course I would have it gone through and have carbs rebuilt, new plugs, water pump, etc to get in tip top shape. What else might I need to do...

    Oil mix ratio trolling 1988 50 hp Merc

    1984 Mercury 50 Renovation

    I inherited a good running 4 cylinder 50 hp with good cylinder pressures, but I was wondering about what are the common things that it would take to upgrade it to tip top shape. Obviously rebuild the carbs, change lower unit oil, new water pump and plugs, but what else might be needed. I was...
