      Frequently Asked Questions: Tohatsu Outboard Parts

      Got questions about maintaining or upgrading your Tohatsu outboard? These quick answers cover some of the most common concerns boaters run into when working with Tohatsu outboard parts.

      Are Tohatsu and Nissan outboard parts interchangeable?

      Yes, Tohatsu manufactured many Nissan outboards, so several parts (especially for models under 90HP) are identical. Just be sure to verify part numbers using your model and serial range before ordering.

      How do I know if my Tohatsu outboard has a two-stroke or four-stroke engine?

      Check your model number: two-stroke models usually have a "T" prefix (e.g., MFS40A), while four-stroke models typically start with "MFS." You can also find this info on the ID plate mounted to the bracket or transom clamp.

      Can I use universal marine parts instead of brand-specific Tohatsu parts?

      Some parts, like fuel line fittings or kill switches, may work universally, but mission-critical systems like ignition, cooling, and internal engine components should always be Tohatsu-specific to ensure proper fit and performance.
