Parts availability for 1990 Merc 90 HP

[isaksp00]

Considering a used 1990 17 foot Invader bowrider, with 90 HP Merc. I assume the motor is same year as boat, but will need to check. Before I waste a visit, are parts available for Merc's of this vintage? Both the standard ones you have to replace (impeller, carb rebuild kits, gaskets, etc.) and others.
Thanks for any insight.

Yes, parts can be purchased, that basic motor was used until at least 2005, maybe a little longer.
