DF90 4 stroke not run for several years

[rsclark115]

I recently bought a pontoon with a 2001 Suzuki 90HP 4 stroke that hasn't been started in several years. After the fuel tank, lines,filters,fuel pumps, and injectors have been cleared of gunk what other issues should I address with this engine?

Change oil and may need a new water pump.

as mentioned, oil change with new filter, while you are fooling around, check the steel screw in plug down below the flush port, just make sure it is not like a few others that have been mentioned here, as long as the fuel is fresh, and the old fuel filter has been replaced, just start it up and run it.
