Nissan 5HP question

[DMGO]

I just got a Nissan 4 stroke 5 HP outboard on Craigslist, and have a question---What year is this motor? The model # is NSF5A2 and then it shows 3H6-1. It starts right up, and idles nicely. Looks like it had very little use. I want to change the plug, lower unit oil, and the crankcase oil. Anything else I should know or do? Thanks

Year is irrelevant when servicing a Tohatsu/Nissan outboard. The 5A2 was made around 2002. The carb for a 6A2 is a direct replacement, and will give you 20% more power. Use NGK DCPR6E spark plug, or the Iridium counterpart, DCPR6EIX.

Thank you.
