Although using higher octane gasolines are a waste of $, on the other hand, more pricey gasolines have better cleaning solvents than cheaper ones, will clean better, burn better, produce less carbon buil up on pistons & cylinder head specially if you are a non carbon guard products user at all.

Re: What octane gas is best to use for a two stroke outboard motor.
The problem of adding an electric fuel pump is to make sure it turns off, if the motor stalls. If you rupture a fuel line, and the motor stalls, fuel will spray all over.
i think that would work better then an electric one they are just too dangerous on outboards here
Re: Adding an electric fuel pump to an outboard [links]
Two-stroke outboard motors with DFI (direct fuel injection) were developed in response to an EPA mandate requiring a 75 percent reduction in exhaust emissions between 1998 and 2006. Since the days of Ole Evinrude, almost all outboard motors used a traditional two-stroke powerhead, which was lighter and less expensive to manufacture than a four-stroke engine. Unlike the four-stroke engine, the two-stroke does not have moving valves to seal the combustion chamber and control the flow of intake and exhaust. In a two-stroke engine the rising and falling piston covers and uncovers ports in each cylinder through which a fuel/air mixture flows into, and exhaust flows out of, the combustion chamber. more
There are plenty of old outboards prowling around out there, and a lot of boat owners like my neighbor. If you've been out of the outboard loop, it may be time to get up to speed with a quick tutorial on the modern two-stroke outboard.
At the same time DFI outboards were being developed, new four-stroke motors also appeared on the market. The new four-strokes also significantly reduced emissions to meet the current EPA mandate, and offered much-improved fuel economy and smoother operation. However, a higher-horsepower four-stroke outboard was heavy, often 100 pounds or more heavier than a DFI two-stroke of similar power. This gave the DFI two-stroke a performance advantage, especially on bass boats and other high-performance boats.
This had to stop, according to the EPA. One alternative was direct fuel injection (DFI), which had been used on four-stroke engines in some World War II aircraft and early fuel-injected automobiles. By aiming a fuel injector directly into the combustion chamber, fuel delivery cam be timed to occur only when the moving two-stroke piston has closed the intake and exhaust ports. Exhaust can still be scavenged from the cylinder by fresh air being pumped through the transfer ports from the crankcase, along with the very small amount of oil required to lubricate moving parts. here
