Cut/creek et al; What maintenance/checks can be done on the old 1999-2005 merc 2-stroke 40/50/60 outboards oil injection pumps? I've read that sometimes the oil pump can sometimes just stop working unbeknownst to the operator and just fry the block with no warning. My '99 has been running 100% and I dont know if anything was ever done to the oil system. Is it just one of those things where it's like..."oh well, time for a new motor!" if it goes out? I know you can switch to pre-mix to avoid this but that defeats the purpose of having an 'advanced' motor...if I wanted to do pre-mix I would buy a barebones 25.
