,
DT55,
DT140, and
DT225.
- Engine layout: These engines were available in 1, 2, 3, V4, and V6 cylinder configurations.
- Oil injection: Some two-stroke models in this era featured oil injection, designated with a “C” or “SS” in the model code, such as the
Suzuki DT8C
or
DT150SS.
- Horsepower: The DT line included models from 2 horsepower all the way up to 225 horsepower, such as the
- DF models (four-stroke):
- Introduction: Suzuki’s first four-stroke outboards were introduced in the late 1990s, with models like the

.
- Early EFI: The larger, higher horsepower four-strokes, like the 2003
, featured electronic fuel injection (EFI).

- Introduction: Suzuki’s first four-stroke outboards were introduced in the late 1990s, with models like the
- Corrosion: Older models used in saltwater can suffer from internal corrosion. A specific issue noted on some DF90-DF140 engines built before 2006 is a steel plug in the alloy engine holder that can corrode out due to dissimilar metals. Checking the internal anodes is vital for preventing corrosion issues.
- Fuel system problems: As with any older engine, especially carbureted two-strokes, dirty or restricted fuel filters are a common cause of poor performance. In carbureted engines, old fuel or ethanol can cause issues, and it is recommended to drain the fuel system if the motor sits unused.
- ECM setup: For 2003 and earlier 90-horsepower four-stroke engines, replacing the electronic control module (ECM) can require a specific setup or programming procedure to avoid performance issues.
- Oil pump wear: As with any used motor, check for proper oil pump function, especially on two-stroke models with oil injection and on high-hour four-strokes.
- Pre-purchase inspection: A thorough inspection of a used engine should include checking compression, lower unit oil condition, and proper function of the trim and tilt system.
- Online marketplaces: Websites like eBay are common places to find used engines, used parts, and repair manuals for specific models, such as a 1996 Suzuki 8hp Dt8c Outboard Motor or parts for a 2002 Suzuki Outboard Motor Df115.
- Authorized dealers and salvage: While dealers won’t sell these new, some may have used motors taken on trade or be able to order parts. Marine salvage yards are also an option for hard-to-find components.
- Repair manuals: Repair and tune-up manuals covering this period, such as the
, are available from retailers like West Marine and The Motor Bookstore to help with maintenance and repairs.
