I have an early 90's mariner 75hp with auto oil feed - I recall reading on the forum that it can be a good idea to disconnect such systems on older 2 strokes and use premix - would that make sense on this particular design? Thank you and seasons greetings!
Personally, they either work or they dont. The crank runs the oil pump, i dont think from memory i have ever seen an oil pump fail on the 75 Clam shell. Some of the MoD engines are clocking up way over 8000 hours with no problems. I would leave it alone!
Thanks a lot guys - sorry for the late reply have been away over christmas - did manage to launch on new years day and decided to follow both your advice and run premix whilst checking if the oil level was dropping!
It does seem a solid engine - despite being stored clearly with fuel in the carbs started and ran - i found out later that 2 float valves were stuck open! hopefully get a carb kit soonest...
