First, sorry if any english mistakes are made, I'm from Sweden
Anyway a Yamaha F100 4-stroke outboard that runs 15-20 hours a year and isn't used for trolling or high speed. after warm up runs att about 4000rpm for 30-60 minutes at a time. the oil is still gold brown when i let it out in the autumn and it feels a waste of oil to the eye anyway.
Could it run two seasons in the boat?, or could I use it in the lawnmowers? or is it not worth it?
the oil is, if serviced at Yam dealer: Shell helix ultra 10W-40 or if I change it myself some medium cheap 5W-40.
