OMC Johnson Evinrude BRP NEW OEM 5031243 Shim Outboard Motor Discontinued 0810

OMC Johnson Evinrude Shim — Part Number 5031243

Brand: OMC Johnson Evinrude | Condition: New Old Stock (NOS)

Genuine BRP / Evinrude Johnson OMC factory part number 5031243, a precision setup shim from the modern BRP-era Evinrude parts system. This number sits in the 50312xx block alongside a known graduated shim range — 5031237, 5031238, 5031239, 5031240 and 5031241 — and alongside gearcase internals such as 5031286, the clutch dog pin spring. It is new old stock from long-term inventory, a genuine BRP component rather than an aftermarket substitute.

Shims are the parts that decide whether a rebuilt assembly runs quiet for a thousand hours or howls and fails. They set bearing preload, gear backlash and pinion depth to within hundredths of a millimetre, and there is no substitute for the exact factory thickness — a technician measures the clearance, reads the shim selection chart, and orders the one number the chart specifies. With Evinrude outboard production ended and BRP's parts pipeline closing out, remaining new old stock is all that exists. Shims in particular are almost never found used in serviceable condition, because they are compressed, deformed and discarded at every teardown.

Condition Details

New old stock. The shim is unused and has never been installed. As with all warehouse-stored inventory, the packaging may show shelf wear, dust, fading, price stickers, scuffs or minor crushing from stacking; BRP small parts of this era were frequently supplied in plain dealer bags rather than branded packaging. The shim itself is flat, uncreased, free of nicks and burrs, and carries its original factory surface. Because thickness is the entire function of the part, we have not cleaned, polished or otherwise disturbed it. Please review all photos, as what is pictured is what you will receive.

Specifications

• Part Number: 5031243
• Part Name: Shim
• Manufacturer: BRP (Bombardier Recreational Products) / Evinrude Johnson OMC
• Part Series: 503xxxx, the modern BRP-era Evinrude parts numbering block
• Sub-block: 50312xx, which contains a graduated shim range and gearcase internals
• Sold: each

Shim thickness, inside diameter and outside diameter are not published in any catalogue data available for this number, and are deliberately not stated here rather than guessed. If you need the exact dimensions confirmed before you buy, message us and we will measure the actual part with a micrometer and send you the figures.

Superseded & Cross Reference Part Numbers

• BRP / Evinrude / Johnson / OMC: 5031243
• Adjacent shim numbers in the same 50312xx block: 5031237, 5031238, 5031239, 5031240, 5031241

BRP's shim ranges of this era are specified in millimetres in graduated steps, typically 0.1 mm apart — the comparable 5036xxx driveshaft shim range runs 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 mm across six consecutive part numbers at the same key position, and the separate 50313xx tappet shim range runs 2.24, 2.46 and 2.58 mm among others. If your service manual gives you a shim selection chart with several numbers for one location, 5031243 is one step on that chart. Measure your clearance and confirm which step it calls for before ordering.

Features

• Genuine BRP / Evinrude factory part, produced to the original thickness tolerance
• Precision setup shim — sets bearing preload, gear backlash or clearance to the factory specification
• Flat, burr-free, unused stock, never compressed or deformed by a prior installation
• One defined step in a factory graduated shim range, so the correct clearance can be dialled in rather than approximated
• From a discontinued product line — Evinrude outboard production has ended, so this is finite, no-reorder inventory
• Shims are routinely destroyed or distorted on removal, so a new factory shim is the only correct way to reassemble

Application

Used in Evinrude, Johnson and OMC outboard motors built under BRP. The 503xxxx numbering block covers the modern BRP-era parts system, so this shim belongs to a later-production Evinrude assembly rather than a vintage OMC motor.

This number does not appear in any publicly accessible BRP catalogue, dealer listing or parts index, so we are not going to guess at a model and year list, and we are telling you that plainly rather than filling the section with invented fitment. What we can say is that the part is a genuine BRP-numbered shim and that its number sits inside a known shim range.

Buyers should confirm 5031243 against the exploded parts diagram and shim selection chart for their specific motor before ordering. If you have your model number and year, or a service manual page showing the shim callout for your assembly, message us and we will work through it with you before you commit. We would far rather spend ten minutes checking than have you receive a shim that is one step off — which, on a shim, is the same as receiving the wrong part.

Why Choose OMC Johnson Evinrude?

Outboard Marine Corporation built Johnson and Evinrude outboards for most of the twentieth century and set the standard for American two-stroke outboard engineering, and BRP carried that line forward through the E-TEC era. Factory-numbered parts were manufactured to tight tolerances and specified for the marine environment, which is why these motors are still running decades later. With Evinrude production ended and BRP's catalogue closing out, genuine factory-numbered parts are a finite supply. On a precision shim this matters more than almost anywhere else — thickness is the entire function of the part, and an approximate substitute is not a substitute at all.
