Mike -

To provide accurate and helpful advice we will need to know significantly more information.

Is your outboard motor a 2 stroke 115 or an EFI F115?

When was the motor last run? Any issues?
How old is the fuel? straight or ethanol blended? Treated with stabilizer?
Was the motor winterized?

If carb'ed, when were they last cleaned?
- gaskets changed?
- synched?

Have the fuel hoses (fill, vent and supply) been changed to alcohol resistant?

Is there a water separator in line with the fuel supply hose? Any debris or water in the cartridge?

Explain the process you take starting the engine and describe the functions of the motor. Does it run smooth at fast idle?
