5/8 inch Stud Dual Eye Rubber Engine Mount | Barr 8-0002

Barr Marine Dual Eye Rubber Engine Mount | Part #8-0002 | 5/8"-18UNF Stud | 550 lb Capacity | Diesel & Heavy Duty Rated | MacombMarineParts.com

Engine vibration that isn't properly isolated doesn't just make for an uncomfortable ride — it accelerates wear on engine mounts, stringers, exhaust connections, and fuel and electrical lines throughout the boat. The Barr 8-0002 dual eye rubber engine mount is engineered to absorb and isolate that vibration at the source, with a cast aluminum base, dual rubber cushion design, and a 550 lb per mount capacity that handles diesel and extra heavy duty inboard applications.

Adjustable vertically for precise engine alignment, with rubber cushions locked to the base and formulated to resist oil and fuel exposure.

Why Engine Mount Quality Matters:

Engine mounts do more than hold your engine in place — they're the primary vibration isolation barrier between your engine and the rest of the boat. Worn or incorrect mounts allow vibration to transmit through the stringers and hull, which over time causes:

• Accelerated wear on exhaust risers, manifolds, and flex joints
• Stress on fuel lines, hose connections, and electrical wiring
• Loosening of fasteners throughout the engine compartment
• Increased interior noise and passenger discomfort
• Potential misalignment between the engine and shaft coupling

The Barr 8-0002's dual rubber cushion design and locked rubber-to-base construction provide consistent isolation performance over the life of the mount, without the rubber walking or separating from the base under load.

Why Choose Barr Marine Engine Mounts:

• 550 lb per mount capacity — rated for diesel and extra heavy duty inboard applications
• Dual rubber cushion design — superior vibration isolation vs. single-cushion mounts
• Cast aluminum base — corrosion-resistant and built for the marine environment
• Oil and fuel resistant rubber — maintains integrity in the engine compartment where spills and vapors are unavoidable
• Rubber locked to base — prevents separation and maintains consistent mount geometry under load
• Vertically adjustable — allows precise engine alignment during installation or realignment

Frequently Asked Questions

1. How do I know if this is the right mount for my engine?
Confirm the stud size (5/8"-18UNF), bolt hole center-to-center spacing (7-1/4"), and hold down bolt size (7/16") match your engine bed and existing mount configuration. Also verify your engine weight per mount is within the 550 lb capacity. If you need help confirming fitment, contact us at MacombMarineParts.com with your engine make, model, and current mount part number.

2. How do I know when my engine mounts need replacing?
Common signs of worn engine mounts include increased vibration felt through the hull and helm, visible deterioration or cracking of the rubber cushions, engine movement under throttle changes, and difficulty maintaining shaft alignment. If your mounts are more than 5–7 years old or show visible rubber degradation, replacement is recommended as part of routine maintenance.

3. How many mounts does a typical inboard engine require?
Most marine inboard engines use four mounts — two forward and two aft. Always replace mounts in complete sets to ensure even load distribution and consistent vibration isolation. Mixing old and new mounts can result in uneven engine positioning and continued vibration issues.

4. Is this mount suitable for diesel engines?
Yes. The Barr 8-0002 is specifically rated for diesel and extra heavy duty applications, with a 550 lb per mount capacity and rubber formulated to withstand the higher vibration loads and fuel/oil exposure common in diesel engine compartments.
