Re: black max 150 trouble
willy, I have only owned one merc. in roughly25yrs. of boating. I was quick to learn, regardless of how much gas you push through that motor,change the h20 seperater often.If manual says every 60 days, make it 30. M ercury carbs are very tempermental. Do what RAP said, take off filter and pour gas in a clean glass jar.You could of had water in the carbs and they may be fouled. What you are describing sounds like what my merc did...had the carbs rblt.,...problem solved and I never let it happen again
