86 evinrude V6 150

[Oshi]

How much horsepower does this engine produce? The VRO has been diconnected and I have heard that this hurts performance..... Not that I want to go any faster than I go, but I would like to know where to power is rated in this year model. Is it at the prop or powerhead. I had this discussion with someone today and he told me at the powerhead? I thought at the prop....:} Is this motor a reliable motor? <br />thank you<br />oshi<br /><br />Lets go fishin!

Re: 86 evinrude V6 150

The hp. of your engine is rated at the prop. Dis abling the VRO won't have any effect on engine performance. The engine is rock-solid and if properly maintained, it'll give you years of good, dependable service.<br /><br />c/6<br /><br />Hooty

Re: 86 evinrude V6 150

Thanks Hooty!<br />one more question <br />Compression Numbers<br />1 100<br />2 100<br />3 100<br />4 105<br />5 96 scary?????<br />6 98<br />These are numbers on a cold engine after sitting a month... Scared or not? They are witing 10 to 12 pounds of each other and have been told that after running, they should come up some. Any opinions? Thanks <br />oshi

Re: 86 evinrude V6 150

Rule of thumb.<br />Readings should be within 10% of each other.<br />Your numbers look fine.<br />Might want to try a "decarb" then remeasure on a warm engine.<br />I expect all number to be up on a warm engine and IF carbon build-up is on rings, "decarb" should help too.<br /><br />Do a search on "decarb". Pleny of info on this sight to assist.<br /><br />Good Luck<br />HAVE FUN!

Re: 86 evinrude V6 150

okay, I need more help Sorry! I was fishing on Saturday and was using fuel from the right tank of my boat. After around 4 gallons were used, the motor was running fine, and as I was planning the boat, the motor just died!!!! It will crank but run for about 2 seconds and spit, sputter and die. I tried to restart several times and again nothing. The motor will fire but then die instantly if I put it in gear or try to idle it up some. Okay, I thought, no big deal, just let it sit and see what happens. I checked the bulb primer and it was not pulling any fuel. I thought that is the problem... So I switch to the left fuel tank (it was full 14 gallons) and It ran about 20 feet and did the same as above! I got gas from 2 different stores.. 87 octane, 50 to 1 oil ratio with evinrude oil. What is the problem? <br /> I pulled the post from the fuel line and checked for leaks or anything that would turn a light bulb on and nothing. I am not experienced with working on the carbs, but could this be the problem? I have changed the impellar last week and checked fluid... I am so frustrated right now, I got rid of a perfectly good boat, and I am having trouble from one that I just got about 2 weeks ago. I pulled the plugs and they looked fine, checked fuel connections, and the boat has a fuel/water separater. Could someone list some possible problems or email me some? Thank you so much for your help from this sight! I wish I could be more help to people here, but with experience I think that I could. <br /><br />The boat is a Ranger 371V, 86 model 150 Evinrude. Thanks for any help!

Re: 86 evinrude V6 150

I was told by a outboard mechanic that a Decarb may be in order. Decarb? What in the world???? I went back to the top and tried to do search on Decarb and nothing specific came up.... Help anyone?

Re: 86 evinrude V6 150

Oshi, I am no expert here, but if primer bulbs are soft, and from symptoms you described, it might be fuel pump not pumping. It will start and run after you prime bulb, but then run out of gas from carbs and quit.

Re: 86 evinrude V6 150

OSHI, I too have an 84' Evinrude 150 and have been having a very similar problem that has been driving me nuts for the last few weeks. Mine will start to run the die just before I get on plane! But my motor doesn't die. I have replaced all fuel lines and it doesn't matter which tank I use I still have the same thing happen. If you find out what it is please let me know. I am as frustrated as you are.

Re: 86 evinrude V6 150

It sounds like the fuel pump to me too. Check first to make sure your fuel lines are good and not pulling air from a leak. If you can keep it running by pumping gas with the primer bulb, it's almost certain it's the pump.

Re: 86 evinrude V6 150

okay, <br />just talked with the mechanic and he told me they have lost the keys to my boat! We talked and I told him the symptoms of the motor and he mentioned it could be the VRO pump going out.... what does it cost? I am not mechanically inclined with boat motors, with trucks, so,so. Could I do this on my on. Again, he said it could not be that and we pulled the plugs, and spark was coming from all 6 cylinders. I guess the fuel pump is a place to start!<br />let me know what you all think!<br />Thanks<br />oshi

Re: 86 evinrude V6 150

Oshi, VRO pump and fuel pump are together, you can fix either one or both. I don't want to start a discussion if it's good to disconnet VRO and premix gas or not, but that would be my option. I just got a '89 150hp, and I will run premix, not sense taking chances.<br />Good luck with your keys...

Re: 86 evinrude V6 150

I am sorry but maybe I am misunderstanding or I probably did not mention it.... the motor has had the VRO disconnected, so I do have to premix the oil to lube the pistons and cylinders. My mechanic said that a fuel pump will be about 50.00 bucks or so and then labor. Does this sound right? Thanks for you post, have you had good luck with your 89 model Evinrude? I guess what I am asking is this: Would you buy another? <br /><br />Thanks<br />Oshi

 

[Valv]

Re: 86 evinrude V6 150

Oshi, nope, the mistake was mine, I didn't pay attention you mentioned VRO disconnected. Anyway, I cannot tell you much about this motor, I just got it and I need to test it soon.<br />I think $ 50.00 + labor isn't that bad at all, depending how much labor. I've heard these are good motors.

Re: 86 evinrude V6 150

please keep me informed about what your opinion is and what experiences you have with yours. I will let all know ASAP about this motor as soon as it is diagnosed. I am under the impression that it will be the fuel pump? I hope nothing serious! Good luck to all and I appreciate the comments and encouragement! Thanks again for a great site!<br />oshi

Re: 86 evinrude V6 150

oshi - One way to check if it is the fuel pump is to take the cover off of the air silencer on the front of the carbs. Get a spray bottle and fill with pre mix. Spray some pre mix in the carbs while someone tuns the ignition switch to start. If it fires that sort of confirms that you have a fuel problem. I would hesitate to let a mechanic loose to replace parts without knowing what is wrong. Mechanics can eat huge holes in your wallet very quickly without knowing what the real problem is.

Re: 86 evinrude V6 150

Just something I noticed - you keep speaking of a (1) fuel pump for 50.00. If you are replacing the oil injection / fuel pump with conventional fuel (only) pumps that motor requires 2. There is a fuel pump that looks like an OIS pump that does not have the oil side but, if I remember correctly, it's more than 50.00 new. <br /><br />Good luck!

Re: 86 evinrude V6 150

okay, here is the verdict as of 3:30 eastern standard time. I talked with mechanic, he changed plugs and took it out on the lake and ran it. He said it ran fine for about 20 minutes then it just died..... and started doing the same mess all over again. What are the signs of this possible being? Anyone help, please! I wish I could say he took the cover off of the carbs and sprayed a premix... but I am not sure if he has tried that or not. All of this work is being done at no charge to me because I just bought the boat. Please help with suggestions.....

Re: 86 evinrude V6 150

Oshi <br />If you just bought it, I would let them figure it out. They will find the problem sooner or later, plus they can run it. Makes a big difference troubleshooting.

Re: 86 evinrude V6 150

If its not pumping fuel manually then the problem is from the bulb to the tank (anti siphon valve, pick up, air leak etc). If the fuel pump is bad, the motor should continue to run if you squeeze the bulb (manually supply fuel to the carbs). <br /><br />I would be concerned about letting the motor die from lack of fuel under a load as you also run out of oil at that point.<br /><br />Obviously running the boat on a different fuel delivery system (six gallon tank and hose) will tell you if the problem is under the hood or forward of the motor.<br /><br />Good luck!

Re: 86 evinrude V6 150

ohsi, has the boat been test ran on a seperate 6 gal. tank with a new fuel line and bulb to the motor. Isolate engine form boat and determine wher the problem lies. does boat have water fuel seperator filter, drain it in to a clean metal pan and check for water.
