CDI Unit for Suzuki 40HP DT40 & DT40C (1986-2017) | OEM 32900-94460

GOOFIT Marine-Grade 6-Wire CDI – Suzuki DT40 & DT40C Series

Proven reliability for the long haul. The GOOFIT 6-Wire CDI Unit is a premium-grade replacement igniter for one of the most trusted workhorse engines on the water: the Suzuki 40HP DT40. Covering three decades of production, this module is engineered to handle the unique electrical demands of 2-stroke marine ignition, providing stable timing and high-energy spark delivery from idle to full throttle.

Marine engines face a brutal combination of saltwater air, high humidity, and constant engine vibration. This CDI features a rugged, weather-resistant housing and fully "potted" internal electronics to seal out moisture and dust, ensuring your motor fires reliably even in the harshest coastal environments.

Why Choose the GOOFIT DT40 Marine CDI?

• Extended Service Life: Unlike standard igniters, our marine-hardened shell is designed to resist the "cracking" caused by thermal expansion and mechanical stress, preventing the internal circuit failure common in older DT40 units.
• Weather-Resistant Reliability: Fully sealed against moisture and salt-spray ingress, this CDI ensures consistent ignition performance whether you are trolling in the rain or running at high speeds in heavy chop.
• Optimized Spark Delivery: Modern capacitor technology allows for a hotter spark during pull-starts or electric starts, reducing the effort needed to fire up the engine on cold mornings.
• Precision Bolt-On Fit: With a mounting hole distance of 72mm, this unit is designed to bolt directly into the factory location on your Suzuki powerhead with no modifications required.
