Default Sea foam vs Quick leen

Which is better for a 1995 mercruiser 4.3 l carbed.

What are you trying to prevent? Sea foam is great for keeping your gas from breaking down plus lubricating the inside of your carb. So is Stabil. But so is pouring a cup of 30 weight oil in the gas tank. Are you having water in the gas line problems? Do you have a water separater filter?

Sorry never heard of the quick keen.

Seafoam and Startron will remove water from the fuel as well as claiming to be cleaners and stabilizers. Mercrury Quickleen appears to be a cleaner.

I use Stable marine for gas with ethanol and Startron. I suspect the are all fine as long as you're using something. I'm more concerned with water and the effects of ethanol.

My grandfather owned a Sohio service station up in the 1970's until he retired. He turned me on to Sea Foam in the mid 70's when I started driving. I use it in all my lawn equipment, the diesel trucks I have owned and my boats. On my 3700 SCR I run both tanks down to just below 1/4 and add 1 gallon to each tank at each fill up. I have no evidence that it works other than I have never had water issues with my fuel.
