Re: Honda 9.9hp Outboard Won't Start
I could be sending you the wrong way here, but gas with ethanol has been a problem on a number of outboards that I know of when the fuel sits for more than 30 days. The ethanol starts to separate out and will cause havoc. Easy to test, get a fuel sample from the huel hose feeding the engine, and pour it in a clean container. Compare it to how it looks versus clean fresh fuel. Then let it sit for maybe 45 mins and see if it separates.
If this is the problem, you'll probably need to clean out the carburator (or injectors), and replace the old fuel with new one.
