Alto 340800 Velvet Drive 5000 Series Inline Overhaul Gasket Set | Replaces Velvet Drive 2001410001

Alto 340800 — Velvet Drive 5000 Series Inline Overhaul Gasket Set | Replaces Velvet Drive 2001410001

Alto 340800 is the complete overhaul gasket and seal set for Velvet Drive 5000 Series inline marine transmissions. It replaces OEM reference Velvet Drive 2001410001. If your vessel uses a Velvet Drive 5000 Series V-Drive transmission, see Alto 340800V instead — the two kits are specific to their respective transmission configurations and are not interchangeable. This kit includes the gaskets, O-rings, and seals required to properly seal the transmission during a complete overhaul — it is a gasket and seal kit, not a full master rebuild kit with friction and steel clutch plates. If you are performing a complete rebuild that includes friction and steel replacement, contact us to confirm the correct full master overhaul kit for your transmission. Alto Products Corp. is a leading manufacturer of marine transmission rebuild components and overhaul kits for Velvet Drive and related applications.

Confirm Fitment Before Ordering

The Velvet Drive 5000 Series encompasses several inline transmission models — confirm this is the correct gasket set for your specific transmission and that your vessel uses an inline (not V-Drive) configuration before ordering. Contact us with your transmission model and serial number and we’ll verify correct application by email, text, or live chat.

Q: What is the difference between Alto 340800 and Alto 340800V?
A: Alto 340800 is the overhaul gasket set for Velvet Drive 5000 Series inline transmissions. Alto 340800V is the overhaul gasket set for Velvet Drive 5000 Series V-Drive transmissions.

Q: Does Alto 340800 include friction and steel clutch plates?
A: No — 340800 is a gasket and seal set that includes the gaskets, O-rings, and seals required for a Velvet Drive 5000 Series inline overhaul.

Q: Should I replace all gaskets and seals during an overhaul even if some look okay?
A: Yes — gaskets and seals are single-use sealing components. Any seal that has been compressed, heat-cycled, or exposed to transmission fluid for an extended period will have reduced sealing performance even if it appears undamaged. Replacing the complete kit ensures a leak-free result and avoids repeat disassembly.
