I have a Mercury Black Max 175hp on a 23 foot 1989 Monza boat. I recently took the boat out and it ran fine going out but coming back it the motor acted like it did not want to run. I do have a 90 gal tank and had to put 28 gallons in to fill it up. The fuel already in it was 50:1 mix and I think I may have put too much oil in it or the previous fuel had a little too much oil in it as well. The motor does not want to stay running unless I idle up a little. My question to everyone is can you put too much oil in the gas to where it makes the boat want to not run?
