Do you have a local airport? They all sell something called 100LL
(One hundred octane, low lead). It's pricey but you probably don't
need huge amounts.

Seeing my Mercury 115 is a 1977, I’d think I’d like it. But carrying 40 gal might shuck a wallet quickly. Lol!

Yeah, those bigger outboards can run through 40 gallons in no time at
all. I assume it's a 2 stroke? If so they seem to be a little less
prone to having the carb gum up. In my experience the problems arise
when the gas and motor sit around for a while. You could keep a
smaller tank of 100LL on hand and run the motor on it for a few
minutes before shutting down. That would help to avoid carb problems.
The other big issue with ethanol fuel is phase separation in the tank
which results in an accumulation of water. The judicious use of
Stabil and/or SeaFoam can help with that but I'd also add a good water
separating filter like a Racor between your fuel tank and the motor.
People are even doing this with dinghy motors.

Yessir, it's a 2-smoker. they guesstimate that WFO they're good for about 11 gal per hr. One advantage to them is the pwr to weight ratio. A 300 lb engine doing about 120 hp. isn't bad.

Not sure how it'll push this 28 ft bi-toon with a moderate load. but at 20 mph it doesn't take you very far on 40 gal.

There is a huge increase in economy if you run around 4000-4500 RPM
instead of WOT, particularly on a pontoon.
A lot of extra power just gets you a moderate gain in speed.
You are right about the weight tho. My old 3 cyl 2 smoke was a 70-90
hp class motor and it weighs the same as my 60-70.
I do use about half the gas I did with the 75 for the same cruise
speed.

Ok I agree. No one says you have to “nail it� and leave it that way. I just used WOT as an example for fuel usage...

My problem was so much water got in the tank, either phase separation or
something else, that the filter would fill up with water. Had about 5
gallons of water in a 60 gallon tank. When coming up on plane, that water
got deep at the pickup.

On the pontoon, I have three 12 gal and a 9 gal backup. I'm not
filling them full due to expansion. and at least I can control the
quality of the fuel and the moisture content. That's about the only
advantage of outboard tanks. LOL

Mine is a 60 gallon belly tank.

My Marquis 22 has a big aluminum -V shaped belly tank. And that's one complaint I have with inboard tanks is with them under the floor, you cant see whats in them, or what kind of shape they're in.

I am surprised builders don't put hatches in over those tanks but I
guess if it goes bad you are going to be cutting a hatch in.

We did have a local station that handled 100 percent gas. No more. They had tank troubles with their diesel tank malfunctioning. They decided to discontinue it's use, and change over the ethanol free. to diesel. now they offer e85, e15 and regular e10 and diesel.

This is sad for the chainsaw, weed eater and a lot of motorcycle crowd. Not counting the boaters. They're hacked about it too. Now the closest place to sell alcohol free fuel is 10 mi away.

Fortunately, the lake I will be boating on with my 2 cycle pontoon has a couple stations that handle it.

it's still inconvenient though.

Find a place that sells this:

https://trufuel50.com/

It's not economical for daily use for boating but it's good for flushing
the bad fuel out of the engine at the end of a season or a long period
on no-use.
