335070 + 343870 Carburetor Float Bowl and Gasket Set Fits Evinrude / Johnson

This XR Marine carburetor float bowl and gasket set is designed for replacing matching float chambers and bowl gaskets on specified Johnson and Evinrude 60° V4–V6 outboard applications from 1991 onward. The set is supplied with three float chamber carb bowls and three carburetor float bowl gaskets for targeted fuel-bowl and seal service. It provides component-level replacement for the float bowls and gaskets rather than a complete carburetor assembly. Before ordering, check the float bowl and gasket part numbers separately against the parts listing for your exact engine configuration.

Fitment

The 335070 + 343870 Carburetor Float Bowl and Gasket Set from XR Marine fits Johnson and Evinrude 90–175 HP, V4–V6, 60° outboard engines with carburetor tank applications from 1991 onward under the specific conditions listed below.

Match the full model designation on your engine identification plate against the application records below, and verify both the float bowl and gasket reference numbers in your parts catalog. Because horsepower and cylinder-angle descriptions alone cannot confirm compatibility across every engine in the 90–175 HP range, check all stated configuration conditions before ordering.

• Brand: Evinrude / Johnson (Application Brand Scope: Johnson) | Power: 90–175 HP | Year: 1991 onward (end year not stated) | Application: Carburetor tank | Engine Configuration: V4–V6, 60° | Restriction: The source does not specify HP-to-cylinder-configuration combinations; do not infer coverage of every engine in the stated range. Confirm both bowl and gasket numbers against the parts listing for your exact engine model.

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. Verify components and prepare the work area: Confirm the engine model designation on the identification plate and check that the three supplied float bowls and three bowl gaskets match the part numbers required for your carburetor setup. Let the engine cool completely, disconnect the battery, isolate the fuel supply according to your service manual, and work in a well-ventilated area away from ignition sources.
2. Remove existing float bowls and inspect mating surfaces: Note the routing of fuel lines and linkages before disassembly. Drain remaining fuel from the float chambers into an approved container and remove the existing float bowls following your service manual procedure. Clean old gasket material from the carburetor body sealing surfaces carefully, and compare the new float bowls and gaskets side by side with the removed components to confirm port, passage, and mounting alignment.
3. Install new gaskets and bowls and check for leaks: Position each new float bowl gasket properly on its mating surface and install the replacement float chamber carb bowls according to the fastener tightening sequence and specifications in your service manual. Reconnect fuel lines and linkages, verify that throttle and float mechanisms move freely without binding, prime the fuel system to inspect every joint for leaks before starting, and only test-run the engine with proper cooling water supply. Stop immediately if any fuel leak 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 the float bowl and gasket reference numbers separately in your engine parts catalog (335070 / 0335070 for gaskets; 343870 / 433000 / 766418 / 0433000 / 0766418 for float bowls).
• Confirm how many carburetors your specific V4 or V6 engine uses and whether a 3-bowl and 3-gasket set matches the quantity required for your planned service.
