343870 Carburetor Float Chamber Bowl Set (3-Piece) Fits Evinrude / Johnson 60° V4 / V6 (90–175 HP)

This XR Marine offering is a three-piece set of carburetor float chamber bowls designed for component-level replacement on specified 90–175 HP, 60° V4 and V6 Johnson and Evinrude 2-stroke outboard applications from 1991 onward. Each package supplies three replacement float chamber bowls rather than a complete carburetor assembly or a multi-part gasket rebuild kit. Please note that the float chamber bowl and the separate float bowl gasket are distinct components with non-interchangeable reference numbers, so verify both your engine configuration and the exact bowl part number before ordering.

Fitment

The 343870 Carburetor Float Chamber Bowl Set (3-Piece) from XR Marine fits Evinrude and Johnson 60° V4 and V6 (90–175 HP) 2-stroke outboard engines in the carburetor float chamber applications from 1991 onward listed below.

Verify the complete engine model designation on your outboard's identification plate and review each application entry below. Compare the full OEM float chamber bowl reference number and confirm that your engine uses the 60° bank angle V4 or V6 configuration from 1991 onward, as horsepower alone cannot confirm fitment.

Installation Guide

General installation overview. Follow the service manual for your exact engine and carburetor configuration. Fuel-system work requires the appropriate skills and precautions.

1. Preparation and Component Verification: Ensure the engine is shut off and cool, disconnect the ignition and fuel supply according to your service manual, and work in a well-ventilated area away from ignition sources. Compare the three supplied float chamber bowls against your existing bowls and verify the engine identification plate and OEM reference numbers before disassembly.
2. Float Bowl Removal and Inspection: Document fuel line routing and linkage positions before removing the carburetor or float chamber bowls as outlined in your service manual. Safely drain residual fuel into an approved container, remove the existing float chamber bowls, and inspect the mating surfaces, floats, and separate sealing gaskets.
3. Reassembly and Leak Check: Install the replacement float chamber bowls with properly matched gaskets and hardware according to the procedures and sequences in your service manual. Reconnect the fuel lines, prime the fuel system, and carefully inspect all bowl seams and fittings for fuel leaks before testing the engine with an appropriate cooling water supply; shut the engine down immediately if any fuel leakage or abnormal operation occurs.

Before You Order

A careful fitment check helps you choose the right part the first time.

• Match the full engine model designation on the identification plate.
• Check the individual year entry and any serial-number or version restrictions.
• Compare the complete OEM reference number, including its suffix. Horsepower or appearance alone is not enough.
• Confirm the package contents and the quantity needed for your repair.
• Verify that your Johnson or Evinrude 90–175 HP outboard is a 60° bank angle V4 or V6 model from 1991 onward.
• Distinguish the carburetor float chamber bowl from the separate float bowl gasket; their part numbers are not interchangeable, and this set includes three float chamber bowls only.
