Intake Manifold
Intake manifold part number: 386662
The number 319230 is the visible casting number found on all three carburetor bodies. It is not the complete carburetor assembly part number.
The complete upper and lower carburetors are both identified as 386268. The complete middle carburetor is 387091.
The carburetors were:
- Completely disassembledi
- Thoroughly cleaned
- Inspected for damage and excessive wear
- Reassembled with Sierra replacement service components as required
- Float levels checked and adjusted
- Linkage checked for proper movement
- Reinstalled as a matched three-carburetor assembly
This assembly has not been tested on a running engine after rebuilding.
Final idle adjustment, synchronization, linkage adjustment and verification of engine-specific jetting may be required after installation by the buyer.

Three-cylinder, two-stroke outboard
This assembly may fit other Johnson or Evinrude 70 HP models that use the same carburetor and intake manifold part numbers. However, OMC used different carburetors, jets, body assemblies and calibration specifications between model years and applications.
Compatibility should be determined by the complete carburetor assembly numbers and the outboard’s full model number—not by the visible 319230 casting number alone.
Before purchasing, compare:
- Complete outboard model number
- Upper and lower carburetor number 386268
- Middle carburetor number 387091
- Intake manifold number 386662
- Carburetor throat size
- Jet sizes
- Linkage configuration
- Fuel-line arrangement
- Primer-solenoid configuration
- All listing photographs
The visible 319230 casting number alone does not establish compatibility because the same basic casting may have been machined, assembled or calibrated for different carburetor applications.
Installation and final synchronization should be performed by someone experienced with multi-carburetor Johnson and Evinrude outboards.
HGS Marine carefully inspects, identifies and describes every part we sell.
You will receive the exact carburetor and intake manifold assembly shown in the photographs. We do not substitute stock photos or a different assembly.
Please provide your complete outboard model number before purchasing if you need help comparing the application.
