Construction and performance

This is a new gearcase assembly (not remanufactured), built from all new OEM and new aftermarket components for maximum durability and long‑term reliability in demanding marine environments.
Internal components such as gears, bearings, and seals are new, giving you a fresh lower unit that restores factory‑correct gear mesh, smooth shifting, and proper gear ratios for your VF250LA.

The housing features a streamlined nosecone design that enhances hydrodynamics and water flow, helping maintain clean water pickup and stable tracking at higher speeds.​
This makes it an ideal choice for performance‑oriented applications where bow lift, holeshot, and top‑end efficiency are critical on VF SHO series outboards.

Installation details

This lower unit is supplied as a complete gearcase assembly designed to install in place of your original Yamaha VF250LA lower unit using standard mounting hardware and rigging procedures.
A water pump is not included with this unit, so you will need to install an appropriate water pump kit during installation to ensure correct cooling system performance.

For best results:

• Reuse or replace with new OEM‑spec hardware, seals, and shift linkage components as needed during installation.

• Fill with the proper grade and volume of marine gear lube recommended for your VF SHO 4.2L V6.

• Verify driveshaft length (20″ L) and rotation before installation to match your existing setup.

Professional installation is recommended, especially on high‑performance boats where engine height, setback, and prop selection are carefully tuned.

Frequently Asked Questions

Q1. Will this lower unit fit my Yamaha VF250LA outboard?

Yes, this gearcase is built as a direct replacement for Yamaha V MAX SHO 4.2L V6 models, including VF250 SHO engines with a 20 inch (L) shaft, which covers VF250LA in that configuration and model year range.
As a technician, I would still verify the exact model designation and shaft length on the engine’s ID plate before ordering, because Yamaha also produced 25 inch and 30 inch versions and those use different lower units.

---

Q2. What other Yamaha engines does this YA‑G6‑07C‑N lower unit work on?

This lower unit is specified for Yamaha VF200 SHO (L), VF225 SHO (L), and VF250 SHO (L) 4‑stroke 4.2L V6 outboards using a 20 inch (L) driveshaft.
Different suppliers list fitment roughly from the 2010 model year through about 2020–2022, so for border‑year engines I always confirm with the serial number before considering it a guaranteed bolt‑on replacement.

---

Q3. What shaft length is this lower unit?

This unit is supplied with a 20 inch “L” driveshaft, which matches the 20 inch transom (L shaft) versions of the VF200, VF225, and VF250 SHO engines.
If your engine is an XL (25″) or XXL (30″) model, this particular driveshaft length will not be correct and you would need a different gearcase built for that shaft length.

---

Q4. Is this a brand‑new lower unit or a remanufactured one?

YA‑G6‑07C‑N is sold as a new gearcase assembly built with all new internal parts, not a remanufactured or rebuilt core.
The similar part number ending in R (YA‑G6‑07C‑R) identifies the remanufactured version, so if you specifically want new rather than reman, make sure you are getting the “‑N” version.

---

Q5. Does this lower unit include a water pump?

No. The manufacturer’s listing for this VF200–250 V6 4‑stroke gearcase clearly states that the water pump is not included.
From a technician’s standpoint, you should plan on installing a complete correct water pump kit for your VF SHO model at the same time you fit the new lower unit, since that is both required for cooling and standard good practice.

---

Q6. What warranty comes with this lower unit?

This new lower unit includes a limited one‑year warranty against defects in materials and workmanship from the gearcase manufacturer.
On top of that, an optional twelve‑month extended warranty is available for an additional charge (commonly listed as an extra fee such as 540 USD) if you want to extend coverage out to a total of two years.

---

Q7. How do I confirm compatibility before ordering?

Most professional suppliers specifically ask you to provide your engine serial number and exact model designation when you order so they can double‑check this lower unit against Yamaha’s fitment data.
As a technician, I also verify that the original engine is a VF200, VF225, or VF250 SHO 4.2L V6 with a 20 inch (L) shaft, and I compare the original lower unit style (nosecone, pickup configuration) to this replacement to avoid any mismatch.

---

Q8. What additional parts and fluids should I have ready for installation?

Because the water pump is not included, you should have the correct Yamaha water pump kit for your specific VF SHO model on hand, plus any associated seals and gaskets.
You will also need the appropriate marine lower‑unit gear lube specified for VF200/VF225/VF250 SHO outboards (commonly supplied in Yamaha maintenance or change kits for these engines), and it is good practice to install new drain and vent screw gaskets when you fill and seal the gearcase.​

---

Q9. Is this a direct bolt‑on replacement, or will my mechanic need to modify anything?

This gearcase is marketed as a direct replacement lower unit for Yamaha VF200/225/250 V6 4‑stroke models in the specified years, meaning no machining or fabrication should be required when the correct shaft length and engine family are matched.
In the shop, we typically swap it on using the original mounting hardware and shift linkage, install the new water pump kit, fill with the correct gear lube, and then adjust shift cable/linkage as needed so the controls engage forward, neutral, and reverse cleanly.
