Run it out or remove the drain screws on the carbs, that's if it is a carbed one.

Four months is boarderline in my opinion. When I know my boat will not be used for several months I fill will 95 octane as it is said that octane rating declines with storage, it will hopefully still be at least the required 91. You could use the storage product - Stabill - expensive - which I have also used over winter. Don't know if it does any good, but I haven't had any fuel storage issues. I think the issue isn't if petrol still works after long storage, but if the octane rating is still high enough to prevent detonation and holed pistons as outboards are often run for long periods at WOT.

Why not leave a small quantity of fuel to keep the system 'wet', then thoroughly drain and fill with fresh fuel at next startup!
