Frequently Asked Questions – Yamaha SHO VF150 & VF175 Lower Unit
1. What Yamaha outboard models are compatible with this lower unit?
This lower unit is designed for Yamaha SHO VF150 and VF175 4-cylinder, 4-stroke outboards manufactured between 2013 and 2024. It supports both 20-inch (long shaft) and 25-inch (extra-long shaft) configurations. Built to OEM specifications, it ensures a direct-fit installation without any modifications, making it a perfect choice for restoring proper function and performance to your SHO outboard.2. What is the difference between the new and remanufactured lower unit options?
The new Yamaha SHO VF150/VF175 lower unit is a factory-fresh assembly using all-new components, while the remanufactured version is rebuilt from an OEM core using inspected, precision-tested gears, bearings, and seals. Both variants meet or exceed Yamaha performance standards, but the remanufactured option offers a cost-effective solution for reliable boating performance backed by the same 1-year warranty.3. Does this VF150/VF175 lower unit come pre-filled with gear oil?
Most new and remanufactured lower units ship without gear oil to prevent leakage during transport. Before installation, always fill the unit with the manufacturer-recommended marine gear lube — Yamaha Genuine Gear Oil SAE 90 or equivalent. Ensure proper torque on the fill and vent plugs using new gaskets to maintain water-tight sealing and prevent gear wear.4. How can I identify whether I need a 20" or 25" shaft lower unit?
Shaft length depends on your boat’s transom height. A 20-inch shaft lower unit fits “long shaft” setups (transom height approximately 20 inches), while a 25-inch shaft fits “extra-long” configurations. You can verify your current lower unit’s shaft length by measuring from the inside of the mounting bracket to the cavitation plate or by checking your engine model code stamped on the bracket.5. What maintenance is recommended for the Yamaha SHO lower unit?
To keep your VF150 or VF175 lower unit performing optimally, replace gear oil every 100 hours or annually, whichever comes first. Inspect the propeller shaft for fishing line damage, check seals for leaks, and grease moving parts regularly. After saltwater use, flush thoroughly with fresh water. Following Yamaha’s maintenance schedule helps extend life and prevent premature gear or bearing wear.
