"Backin the day" I had several 4 & 6 cylinder carbd outboards & while I certainly never had to deal with corn juice like we have today, I still pulled the fuel line at the end of the day on the trailer at the ramp & I let the motor run til it died. Never a fuel problem.

Now I have 3 outboards, a ol 2cyl 50hp carbd Erude on my 16ft aluminu basser. I still pull the line at end if day & run it til dead. I have a 150DI Erude on my 22ft deckboat. Obviously can't pull that line but I keep Stabil Marine in it (1oz to 5gal, all the time). I do the same with my Mercury 225XS Sport (a high perf Optimax) on my 21' Allison basser. I run a can of B12Chemtool thru each of them 2ce a year!

I use Stabil Marine in essentially everything I have that burns gas (7 vehicles, 3 boats, 3 ATCs & lots of gas powered tools on my farm). & Stabils diesel formula in my 70hp Kubota. I'm also a big believer in 1-2 cans of B12Chemtool in everything 1-2x a year (NOT the tractor!)
