Hello All:
This may seem like a dumb question, but I'm not sure what type of engine we have. The mechanical survey we had done when we purchased the boat a few months ago indicated we had a 32hp, 4 cylinder Universal 5432.
Someone recently suggested that Ericson in the mid/late 1980's changed over to an M-40 Universal. This has bearing on trying to resolve a problem we have where diesel fuel (15% as analyzed) is getting into the oil system.
The 5432 apprently has a low pressure , oil cooled mechanical fuel pump with a diaphragm that could be the source. The M-40 has an electric pump that would accordingly point to the high pressure fuel injector pump as the diesel fuel leak source, which is also oil cooled (we do have an electric supply pump, upstream of the fuel filters, making me think we in fact have an M-40).
Any thoughts or comments would be very helpful.
regards,
Kerry
