Changing lower-unit oil shouldn’t be a juggling act with funnels and slippery gear lube. The Suzuki Gear Oil Pump (990C0-99002) threads onto any one-quart bottle of ECSTAR—or your favorite 80W-90—then snaps into the fill port on every modern Suzuki outboard from DF2.5 to DF350A. A few smooth pumps send thick oil uphill without air pockets or messy drips.

Built for salt-life durability, the pump body is molded from solvent-resistant polymer and rides on a stainless piston rod that won’t seize after a season rattling in the tool box. The clear 26-inch hose lets you watch for bubbles, while a brass 8 mm adapter seats snugly in the drain-plug threads—no Teflon tape required.

Why it belongs in your service kit:

• Fits standard 1-quart/946 ml bottles and every Suzuki lower-unit fill port
• Transparent hose for visual flow confirmation and quick cleanup
• Corrosion-proof materials shrug off gear oil and salt spray
• Wide flanged handle gives steady leverage even with wet gloves

Stow it with your spare crush washers and each fall service becomes faster, cleaner, and far less wasteful.
