I rand a 1997 130 Yamaha up until last year. Sold it to my kid who is still running it. over 2000 hrs.
2 Oil Lift Pumps (Magnets fall off of the housing)
1 Bearing under the Water Pump from low Lower Unit Oil (just checked it yearly for water, drained enough over 2 years to run the bearing dry)
Drain Carbs the end of each year, Plugs every second year, LU Oil Change every second year, and go.
