97 Evinrude 225 cutting out at 4000 RPMS

[robayles]

A couple of nights ago I almost ran out of fuel. Got to the marina and there was very little fuel left in the tank. Idled down to a restaurant for dinner, returning to the boat a couple of hours later. Boat started fine, idled fine (no wake zone)and after about 5 minutes the motor died. Wouldn't restart. Bulb wouldn't get hard. Towed for a while by Sea Tow with motor in gear and eventually the motor restarted. Got back to the dock. Next day bulb was still firm, motor started fine, idled fine but at 4000 rpms it seemed like motor wanted to cut out. It ran fine if I kept it around 3200 rpms.<br /><br />Sea Tow said it didn't appear that gas was getting in the motor. Would the VRO pump still push oil into the motor while cranking if no gas was going in? Is this related to the problem?<br /><br />Any ideas?<br /><br />The Big O

If no gas was going into the VRO pump, you should have gotten a no fuel flow alarm.

First of all you dont have a VRO pump. You have an oil injection / fuel pump. That may save some confusion in the future.<br /><br />When you ran the tank that low you may have picked up debris from the bottom of the tank. Check your water seperator filter. If it has crud in it, some may have gotten to the carbs. <br /><br />You may also have some in the anti-siphon valve in the tank. You may want to look at that.

Hi Dhadiey<br /><br /> I have a 1995 Johnson 130 hp,does this motor have a VRO or an oil injection fuel pump?<br /> Tanks J,C,

Re: 97 Evinrude 225 cutting out at 4000 RPMS

JC, that should have the straight ratio pump also. Not the variable (VRO) pump.

Thanks for clarifying what type pump I have. Would it help to use something like Seafoam in the tank to clean out the carbs?<br /><br />Also, I'd like to say, as a new boater, this site as been incredible. I have been able to solve a couple of issues in the past through this site without having to pay $$ to get the work done.<br /><br />The Big O

I checked the fuel/water seperator and it did have some crud in the bottom. I don't know the last time it was changed but I went ahead and put a new filter on.<br /><br />The engine started up fine but quit after a couple of minutes. It seems it used the fuel that was still in it and then wasn't getting any more fuel. I primed the bulb over and over but it wouldn't get firm. Now the engine won't start. The bulb had been getting firm before I changed the fuel/water seperator.<br /><br />Any ideas what may be happening?<br /><br />The Big O

Dhadley if he ran out of fuel wouldn't it fill the carbs with oil? Could this be the problem, one carb may be plugged up?

Re: 97 Evinrude 225 cutting out at 4000 RPMS

Well, I feel pretty stupid. I called a mechanic and described the problem. He knew immediately what was wrong. The Racor fuel/water seperator for OMC's as a bowl at the bottom with a drain. The drain is a screw. Its screwed in to drain, not out as I had it. Not allowing a vaccum for the bulb to prime. Problem solved, at least with the fuel water seperator. Now I can go out and see if that solved the original problem.<br /><br />The Big O

Dont feel bad! Thats great info to pass on. Good luck with your test run!

Re: 97 Evinrude 225 cutting out at 4000 RPMS

Have checked everything fuel related and everything checks out. Still having problems with intermittant missing at med and high rpms. Also, failed to mention that Tach went out during all this as well. Beginning to think this is related. Now having problems with engine dying and won't restart. Got towed back to the dock twice and a little while later the engine will restart. Is this powerpak related?<br /><br />The Big O

Re: 97 Evinrude 225 cutting out at 4000 RPMS

Can someone please help me with this? I'm trying to determine if I have a powerpak, stator or rectifier issue.<br /><br />The Big O

Re: 97 Evinrude 225 cutting out at 4000 RPMS

Please help. I have a mechanic working on it now and he says its the stator and the powerpak. The stator to fix the engine shutting off problem and tach problems, and the powerpak to address the engine missing a mid to high rpms.<br /><br />Is he on the right track?
