Mercury MerCruiser Gimbal & Bell Housing Screw — Part No. 10-34763 | Pack of 5
This listing is for a pack of 5 genuine Mercury Marine OEM screws, part number 10-34763 (base number 34763). These screws are used in select legacy Mercury and MerCruiser sterndrive gimbal housing and bell housing assemblies where the parts diagram specifically calls for this number. Having a full pack on hand is practical for any sterndrive housing service — multiple fasteners are typically replaced at once, and having spares prevents delays if one is damaged during removal.

When to Replace
Replace these screws any time they are missing, corroded, stripped, seized, rounded, bent, or damaged during gimbal housing, bell housing, or sterndrive service. On legacy drives with significant service history, corrosion and thread damage are common — having a full pack on hand before teardown avoids mid-job delays.
Installation Tips
- Confirm the correct diagram location and fastener stack-up before installation
- Inspect mating threads in the housing for corrosion or damage before installing new screws
- Follow Mercury service procedures for torque specification and any approved thread treatment at this location
- Do not substitute generic hardware-store screws — OEM fasteners are specified for the material and coating appropriate to the marine housing environment
- On older drives, consider replacing all housing screws as a set rather than only the damaged ones
Technical FAQ
Q: Why buy a pack of 5 instead of individual screws?
A: Gimbal and bell housing service typically involves multiple fasteners at once. Buying a pack ensures you have enough to complete the job and keeps spares on hand for the next service. On older drives, it’s common to find more than one corroded or damaged screw once the housing is apart.
Q: Can I use a generic screw of the same thread size?
A: Not recommended for housing assemblies. OEM marine fasteners are specified for corrosion resistance and material grade appropriate to the sterndrive environment. A generic substitute may corrode faster or not meet the clamping requirements for the housing joint.
Q: My drive serial number isn’t listed — will this fit?
A: Fitment on legacy MerCruiser drives must be confirmed by serial number and diagram. If you’re unsure, our parts team can help verify before you order.
Parts Desk Insights
Best use case: This pack is the right choice for any technician or owner doing gimbal housing, bell housing, or sterndrive reassembly on a legacy Alpha One, TR/TRS, or MerCruiser II/III drive. Ordering a pack before teardown — rather than individual screws after discovering damage — keeps the job moving. It’s also a smart add-on alongside bellows kits, gasket kits, and seal kits for complete sterndrive service.
Common mistakes: The most frequent error is assuming all housing screws on a legacy drive are in good condition until they’re actually out. Corrosion and thread damage are common on older drives, and discovering a stripped screw mid-job without a replacement on hand causes unnecessary delays. The second common mistake is substituting a hardware-store screw by thread size alone — which may not meet the corrosion resistance or grade specification for a marine housing application.
