re: Mercury 150 4 stroke outboards

I have the rolled edge version, it’s supposed to be 1350 lbs. I have added a lean post, three batteries, a charger, a jack plate, and an ipilot. I usually have around 30 gallons of fuel, two guys, and a big ice chest.

I started w a 23 prop and ran 53ish really light but I didn’t get enough rpms. I’ve kept going down trying to find the right one. Now I have a 18, I do 47ish light but it gets on a plane almost instantly. I think a different prop might go faster.

I’m not the best guy to ask about fuel economy, I hover around 4500-4600 rpms everywhere I go. Most of the the time I check, I’m right around 4mpgs.
