Changing Spark Plugs- OB motor

[Eastporter]

Do you change spark plugs each season? I've got a Suzuki 80 hp outboard (4 stroke) with about 20 hours. Do you think I can go another season?

No need to change that often on a four stroke.

Thanks! Do you go by hours or number of seasons used?

I have owned mine for 7 seasons. Changed the 2 years ago and the old ones looked fine.
