Here you will find Evinrude service manuals and Evinrude owners manuals for 2011 or newer Evinrude outboard engines. For Evinrude service manuals or Evinrude Johnson® owners manuals for 2010 models and prior, please contact the Ken Cook Company at (414) 466-6060 or click here Antique Literature to be directed to their website Antique. Re: What year was the Last V 4 140 HP 2 cycle Evinrude/Johnson? I had a 1979 Johnson 140-4cyl. On a Sea Ox I bought in 1984. Nice engine, right up until the moment in 1989 that I found small bits of metal in some of the plug gaps. Low compression on 1 or 2 cyls.

Fuel Pumps General Information FUEL PUMP DESCRIPTION/OPERATION The fuel pump is a crankcase-pressure-operated, diaphragm- type pump. Crankcase pulsating pressure (created by the up-and-down movement of piston) is transferred to fuel pump by way of a passage (hole) between crankcase and fuel pump. When piston is in an upward motion, a vacuum is created in the crankcase, thus pulling in a fuel/air mixture (from carburetor) into crankcase. This vacuum also pulls in on the fuel pump diaphragm, thus the inlet check valve (in fuel pump) is opened and fuel (from fuel tank) is drawn into fuel pump. Downward motion of the piston forces the fuel/air mixture out of the crankcase into the cylinder. This motion also forces out on the fuel pump diaphragm, which, in turn, closes the inlet check valve (to keep fuel from returning to fuel tank) and opens the outlet check valve, thus forcing fuel to the carburetors. CHECKING FOR RESTRICTED FUEL FLOW CAUSED BY ANTI-SIPHON VALVES While anti-siphon valves may be helpful from a safety stand-point, they clog with debris, they may be too small, or they may have too heavy a spring. Summarizing, the pressure drop across these valves can, and often does, create operational problems and/or powerhead damage by restricting fuel to the fuel pump and carburetor(s). Some symptoms of restricted (lean) fuel flow, which could be caused by use of an anti-siphon valve, are: 0001 Loss of fuel pump pressure 0001 Loss of power 0001 High speed surging 0001 Preignition/detonation (piston dome erosion) 0001 Outboard cuts out or hesitates upon acceleration 0001 Outboard runs rough 0001 Outboard quits and cannot be restarted 0001 Outboard will not start 0001 Vapor lock Since any type of anti-siphon device must be located between the outboard fuel inlet and fuel tank outlet, a simple method of checking [if such a device (or bad fuel) is a problem source] is to operate the outboard with a separate fuel supply which is known to be good, such as a remote fuel tank. If, after using a separate fuel supply, it is found that the anti-siphon valve is the cause of the problem, there are 2 solutions to the problem; either (1) remove the anti-siphon valve or (2) replace it with a solenoidoperated fuel shutoff valve. Testing Install clear fuel hose(s) between fuel pump and carburetor( s). Run engine, and inspect fuel passing thru hose(s) for air bubbles. If air bubbles are found, see “Air Bubbles in Fuel Line,” below. If air bubbles are NOT found, see “Lack of Fuel Pump Pressure,” continued on next page. Troubleshooting Fuel Pump PROBLEM: AIR BUBBLES IN FUEL LINE Possible Cause Corrective Action Low fuel in fuel tank. Fill tank with fuel. Loose fuel line connection. Check and tighten all connections. Fuel pump fitting loose. Tighten fitting. A hole or cut in fuel line. Check condition of all fuel lines and replace any found to be bad. Fuel pump anchor screw(s) loose. Tighten all screws evenly and securely. Fuel pump gasket(s) worn out. Rebuild fuel pump. PROBLEM: LACK OF FUEL PUMP PRESSURE Possible Cause Corrective Action An anti-siphon valve. Read “Checking for Restricted Fuel Flow, Caused by Anti-Siphon Valves” preceding. Air in fuel line. “Air Bubbles in Fuel Line”, preceding. A dirty or clogged fuel filter. Clean or replace fuel filter. The fuel pickup in fuel tank clogged or dirty. Clean or replace pickup. Worn out fuel pump diaphragm. Rebuild fuel pump. Defective (hole or crack) check valve(s) in fuel pump (unlikely). Rebuild fuel pump. Broken check valve retainer. Rebuild fuel pump. Pulse hole plugged. Remove fuel pump and clean out hole.

Troubleshooting Fuel Pump (continued) PROBLEM: LACK OF FUEL PUMP PRESSURE Possible Cause Corrective Action Hole in pulse hose (1 pulse hose). Replace pulse hose. Loose pulse hose. Tighten connection. Boost diaphragm gasket distorted or out of place. Check seal between mating surfaces where “rib” divides pulse chamber – gasket must align with rib; check for distorted gasket. Align or replace gasket if necessary. Fuel Pump Components (Design 1) NOTE: In fuel pump reassembly, remember that respective diaphragms go against the mating surfaces of the fuel pump body, and respective gaskets are between the diaphragms and end caps. Gaskets should always be replaced on fuel pump assembly.
