**When you cleaned the carbs, did you remove the main and idle jets(and look thru them)? Or just spray the outsides? (be honest please).

Those idle jets are pretty darn small and easy to clog.
If the fuel is older than a month and un-stabilized, it's likely bad. Dump it and get fresh fuel B4 trying to crank it up again. Un-less you enjoy "do-overs" [links]
Has it sat for awhile with old, untreated fuel in the engine? more
After isolating the leak, you can cut a part of the fuel line, fix the problem, and reattach the barb or attach a new hose. Alternatively, you can replace a hose clamp. If the fitting is damaged, you may choose to push to one side to get your engine running temporarily. After that, your engine’s draw is mostly sufficient to maintain the flow of the fuel running well. more
During winter, you have to winterize your motor, or the fuel will go bad. Use a good stabilizer to stabilize fuel in your tank. Adding stabilizers to your fuel tank before going for the final trip before the winter season begins will ensure all the fuel lines are well catered for during the entire winter season. In addition to these, some boaters prefer to service their motors before storing them for winter. When you service and treat your motor before storage, you will be assured of getting a properly functioning motor at the beginning of the new season. Some of the reputable stabilizers include Mercury Marine and Yamaha. You can also opt for an aftermarket product dubbed the SeaFoam (view on Amazon) that works just as good as any other stabilizer from a reputable manufacturer.
In some cases, the engine becomes starved of fuel and fails to start. This happens over and over because of cheap quick-disconnect fittings attaching the boat’s fuel line to its outboard. This is also true for the boat barbs that attach the fuel lines and fittings or the hose clamps that secure them. All these connections begin leaking over time and allow air to leak and get stuck inside these parts. more
When dealing with an outboard motor, you need to take care of your water pump. Make sure you check your boat’s water pump every year to ensure it is in good working condition. A faulty water pump might send you to a mechanic shop frequently. This is not only costly but also inconvenient. Most boat manufacturers advise boaters to check their impellers every three hundred hours or after every three years. However, making a habit of inspecting it at the beginning of every season will ensure you have a well functioning water pump.
DF115 (2012, 217 hrs) . Shut off starboard motor yesterday waiting my turn at ramp, now won’t start. Motor turns over, does the initial fire-up for 3-4 seconds and then shuts down. Fuses checked: PPT SW, fuel pump, ignition coil, injector, ECM and IAC, all good. Good spark on all cylinders, low pressure and high-pressure pumps working. Squirted starting fluid into air box, same results, initial fire for a few seconds then dies. Swapped ignition harness (dual engine switch panel), same results, initial start then dies. more
Swapped out IAC valve, no changes. Then removed IAC from manifold, motor started and continued to run.
Reinstalled IAC, disconnected throttle cable and inserted .032 safety wire to barely hold throttle body plate open. Result; started fine and continued to run with no issues. As expected, did not get the initial high RPM and down to idle.
If your boat has an emergency shutoff switch, check that the cap is firmly in place or the engine might not start. [links]
If your battery is holding adequate charge, the cables or connectors may be faulty. Check and clean the battery terminals and connectors to rid them of any corrosion buildup. Inspect the cables for any cracks, corrosion, or other obvious signs of wear that may impact their performance. Once the terminals and connectors have been cleaned and the cables have been inspected, securely attach them back to the battery and see if this solves the issue. here
Most outboards will not crank if the boat is in gear. If the engine won't crank but other lights and gauges work correctly, check that the gear shift is in neutral. here
If your boat has a battery switch, ensure that it's switched to the on position and try again. more
If you experience trouble starting the engine, engine hesitation, loss of power, or decreased acceleration, you may have failing spark plugs. Check the spark plugs for signs of damage. Any spark plug that contains moisture or black soot indicates that it is damaged and should be replaced. [links]
We've all been there - your boat is in the water and packed with guests and gear. You're finally set to take off and go to crank the motor only to find that the boat won't start. Along with a few choice words, your first reaction will probably be something along the lines of "oh great, I wonder how much this is going to cost me".
