Suzuki DT55 DT65 2-Stroke Starter Motor 12V 9-Tooth 1985-1997

Overview

Direct-drive 12V starter motor for selected Suzuki DT55 and DT65 three-cylinder two-stroke outboards. It uses a 9-tooth pinion and is designed to replace the original Hitachi-pattern unit when the engine model, production year, mounting and OEM references agree.

Technical specifications

Engine compatibility and OEM references

• Suzuki DT55 55HP two-stroke: selected 1985-1997 models.
• Suzuki DT65 65HP two-stroke: selected 1985-1997 models.
• Known variants may include DT55CHL, DT55CRL, DT55CRS, DT55TCL, DT55TCS, DT65CL, DT65TCL and DT65TCS, subject to year and original-part verification.

OEM references to compare: 31100-94702, 31100-94701 and 31100-94700.

Confirm the full model code from the transom-bracket identification plate and compare the original starter. A DT55/DT65 badge alone does not guarantee fitment.

Installation and pre-fit checks

• Disconnect the battery before work and photograph the original cable routing.
• Compare the 9-tooth pinion, 28.9mm gear diameter, mounting flange, drive position and terminal orientation with the old starter.
• Inspect the flywheel ring gear, solenoid, battery, positive cable and engine earth for faults or excessive voltage drop.
• Clean the mounting surface and tighten fasteners and electrical terminals to Suzuki specifications.
• Test for smooth engagement and immediate disengagement. Avoid repeated long cranking periods.

Frequently asked questions

Q1. Will it fit Suzuki DF55 or DF60 four-stroke engines?
No. This starter is for selected DT55 and DT65 two-stroke applications, not DF-series four-strokes.

Q2. Are all DT55 and DT65 years compatible?
No. Check the full model code, year or serial range and original OEM reference before ordering.

Q3. What are the key physical checks?
Confirm 12V supply, 9 teeth, approximately 28.9mm pinion diameter, rotation, flange and terminal position.

Q4. Why should the electrical system be checked first?
A weak battery, high cable resistance, faulty solenoid or damaged ring gear can mimic starter failure and can damage a new unit.
