Hi all
I just bought a 22 walk around with an 86 150 Evinrude, The original owner had used it quite regularly but the guy I bought it from hardly did in the three years he owned. It had about twenty gallons of two-year-old gas in it, which I mixed with 60 gallons of fresh gas when I filled it up. To my knowledge hat was the first time Ethanol gas was put into it. She ran great most of the day with a few sputters towards the end. The following weekend, different story she ran fine for about five miles I shut her down for a while and tried to go again. She starts fine and revs up fine but put it in gear under a load and she just bogs down. I had to idle all the way back to port.
The next day after a new filter/water separator and some carburetor cleaner the same thing happened. After motoring a mile out the river into the bay she jumps right up to speed but after running a while and slowing down trying to throttle up she wont go. Only now if I keep playing with the throttle she will finally catch on and speed up.
With all the complaining I am hearing about E10 gas and boats I am thinking it has got to be the gas or now clogged up carburetors. When I removed the intake cover to clean the carbs there was quite a bit of what looked like blue tinted Vaseline in some of the ports and jets. I am assuming it was blue from the oil. She does seem to run much better after squirting down the carbs but then its back to the same old thing.
I changed the plugs for good measure. I changed the gas filter, which was filthy with lots of water in it. I disabled each spark plug one at a time at idle speed as ancient mariner suggested to littleb99, I did not always notice a loss of power however I did confirm spark at each cylinder. One plug wire seems to be leaking electricity when touched. Luckily it wasnt me that found out.
I still need to do a compression check but I am thinking it still has to be the carburetors gunked up.
I ran the original tank of gas out and used a portable to get home, same problems with that hopefully ruling out check valve problems. Now I am on all fresh new E10 fuel.
The other thing I noted was that I have a Racor B32013 filter/ water separator, which I replaced in kind. In looking in the West Marine catalog afterwards I noted that filter is a replacement for Mercury outboards while the B32014 is specified for Johnson/Evinrude. Would that make much of a difference? I do seem to have good fuel supply as I could see it flowing into the carbs under full load without the cover on.
Sorry for being long but I wanted to be as detailed as I could, you guys have been a great help already from reading your previous posts
