Will not stay running

[mav6759]

I have a 1988 60hp Evinrude (E60ELCCR). Problem is I can't keep this motor running. I brought this motor from a marine repair shop about 11 months ago. He told me that he just rebuilt the head, and he was suppose to swap out the motor for me, but he kept my boat for about year. He final confussed that he couldn't get the low unit to work with the motor. Being upset that he kept my boat for so long, I went and got my boat. The engine was mounted, but the lower unit was not. So I had another local marine shop bolt the low unit up. The only thing he said was I need a water pump. So I had that done. Now, I put on muff's yesterday and it ran fine, forward and reverse, but when I got it down to my local lake, it ran for about 2 minutes and die, a 1 mintue and die, 30 seonds and die. A friend on mine that works on all the county boats made adjustment after adjustments, nothing. Could this be a lower unit problem, or an engine problem, What am I missing, Please I need help

Will it stay running if you constantly pump the fuel primer bulb?

No it will not stay running, that the problem, we have tried everything we can think of short of the fuel filter, but it ran for as long as we wanted it to run while it was on muff's.

Re: Will not stay running

well when the motor is on muffs, there is no load on the prop. and usually if you think it idles smooth on the muffs, then put it in the waters it runs poorly usually when the synk, and timing are right, the motor should races up a little bit on the muffs, and run smoother in the water, you should also never shift into gear on the muffs due to the no load on the prop. thats how you damage the lower unit,and blow water pumps,from personal experiance! so make all adjustmants in the water or large test tank.

Could this be a cylinder problem, could it be that all cylinders are not firing or lower compression. Also, we did do adjustments on the water and it still won't act right. Or could this be a fuel filter problem or a carb's. Out of 3 different marine shops we still can't fine the problem.

Re: Will not stay running

Fiddling with adjustments is not a diagnostic procedure. Check compression. Check spark using a spark tester. Spark needs to jump a 7/16 gap with a good solid snap. Run the engine on a different tank. (I will surmise you are using fresh fuel and not fuel that's a year old). What do the spark plugs tell you? Are they wet with fuel, bone dry, pure white, tan, black with sooty residue? I doubt the problem is in the lower unit. You have a compression, fuel, or spark problem. If the engine was rebuilt, were the carbs rebuilt as well as very often they are the reason the engine went bad initially. If they weren't rebuilt they could cause engine failure again.

Re: Will not stay running

Thank you for your response, We tried using another tank of fuel and disconnected the VRO and mixed the oil by hand with new fuel. We had the dame problem. I will have a compression test done on the motor, if I fine out that this person lied to me, after all the problems I had with this motor, I'm going too tke this motor back to him and it not going to be pretty.
