Star Brite 27405 5-Gallon Lower Unit Lube Pump
Built for high-volume marine maintenance, the Star Brite 27405 is a heavy-duty lube pump designed to transfer gear oil directly from a 5-gallon pail into outboard and sterndrive lower units. With a 96" (8-foot) hose and a 3/8"-16 threaded fitting, it gives you the reach and control needed to service multiple engines efficiently — without the mess of squeeze tubes or funnels.
Sturdy construction is built to hold up to repeated use in a shop or marina environment, making this a practical long-term investment for anyone servicing more than one boat or performing regular fleet maintenance.
Key Features
- 96" flexible hose — reaches lower unit fill ports from a floor-level pail with ease
- 3/8"-16 threaded fitting — secure, leak-resistant connection to the lower unit fill port
- Compatible with 5-gallon pails — ideal for bulk gear lube applications
- Heavy-duty construction — designed for repeated professional use
Best Use Case
This pump is the right tool for marina service departments, mobile marine mechanics, and serious DIY boaters who maintain multiple outboards or sterndrives and buy gear lube in bulk. It eliminates the per-service cost of squeeze tubes and speeds up the lower unit service process significantly. If you're servicing a single engine occasionally, the squeeze-tube adapter fittings are a more economical choice — see the Star Brite 28402 Adapter Fitting (MerCruiser, OMC, Evinrude, Volvo & more) or the Star Brite 28401 Adapter Fitting (Yamaha, Nissan, Tohatsu & Honda).
Pair this pump with Star Brite gear lube in bulk format — see the Star Brite Synthetic Blend 80W90 Gear Lube (1 Gallon) or the Star Brite High-Vis 80W90 Gear Lube (10 oz) for squeeze-tube top-ups.
Parts Desk Insights
Best use case is marina shops, mobile mechanics, or multi-boat owners buying gear lube by the pail. The 3/8"-16 thread is a standard fitting but confirm compatibility with the customer's lower unit before recommending — some engines require an adapter. This is a strong upsell for any customer purchasing a 5-gallon drum of gear lube. For single-engine recreational customers, redirect to the 28401 or 28402 squeeze-tube adapter fittings instead, which are a better fit for occasional home use.
