Alarm problems

RIVER BOAT JOE

New member
I have a evinrude 225 vendicator and it runs great. but when I come out the hole and get going a check engine alarm and light come on. And it dont do it all the time. Any help would be appreciated.
 
Bump^^..... I don't have the answer to your problem as I retired before that model came into existence BUT I did want to "bump" it to the top of the list for other members to review.
 
Maybe i should reword it. But i dont think its a alarm problem. its something but the boat runs fine. maybe some type of fuel problem ? Does anybody know how many fuel filters this engine has ? Someone told me there might be a filter in the fuel tank.
 
Check engine means that you have a fuel restriction. The sensor for it is on the incoming fuel line, right near the fuel pump, kinda a strange looking switch, round with a rectangular plastic block coming off it, a wire harness connecting, and a very small fuel pressure line going to the round diaphragm part. When this switch detects too much suction in the incoming fuel line, it triggers the alarm. Look for clogged filters, clogged tank pickup, or bad primer bulb. What does the primer bulb do? Does it suck flat? If so, the restriction is toward the tank, or the bulb itself. It could also be a bad sensor. But it is not something you should ignore, or disconnect.
 
After reading Daselbee's explanation, I would add the following.............

(Fuel Anti Siphon Valve)
(J. Reeves)

Many of the later OMC V/6 engines incorporate a fuel restriction warning via a vacuum device attached to the powerhead. If the engine overheats, or if you have a fuel restriction, the warning is the same.... a steady constant beep.

NOTE... Only the V/6 & V/8 engines have the above "Fuel Restriction Warning". The warning horn will not sound on the other models.

The fact that a engine is not overheating, but the warning horn sounds off with a constant steady beep, and that the rpms drop drastically would indicate that the engine is starving for fuel due to a fuel restriction. Check the built in fuel tank where the rubber fuel line attaches to the tank fitting. That fitting is in all probability a "Anti Siphon" valve which is notorious for sticking in a semi closed position. It will be aluminum, about 2" long, and the insides of it will consist of a spring, a ball, and a ball seat. If this valve exists, remove it, knock out those inner components which will convert it to a straight through fitting, then re-install it. Hopefully that cures the problem.

The above procedure will cure a restriction problem with the anti siphon valve as stated. BUT, it may also allow fuel to drain backwards to the fuel tank when the engine is not running (siphoning backwards) due to the fact that the carburetors/fuel pump etc are higher than the fuel tank. This condition is not an absolute as the valves in the fuel primer bulb usually prevent this backwards siphoning problem. However.... if this does take place, the cure would be to install a new anti siphon valve.

NOTE: There has been cases when the output valve in the fuel primer bulb would come apart, and the inner portion of the valve would actually reverse itself and be drawn back into the primer bulb's output valve body. This in effect would create a shut off valve and result in a fuel restriction. If this is the case, you should be able to feel something laying in the bottom of the primer bulb when held horizontally.

Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay auction at:

thanks guys for the help. the bulb does not suck flat or feel real soft. when i prime it it will get hard. going to cheeck everything out and go from there. at least you guy gave me a place to start checking.
