The Palmer gasoline engines are pretty cool, old, simple engines. A distant cousin to my Atomic 4 in some ways.
For starters you can ignore postings from people who say they do not have a gasoline engine on their boat.
40 year old gasoline engines were not engineered for lead free gas with ethanol as a bogus additive of up to 10%. When we got our Atomic 4 that came with our 43 year old Tartan 27' the previous owner (PO) left a can of lead substitute on board and I think our old engine likes it. I'm not sure about the Palmer but for the Atomic 3 or 4 we also routinely put some Marvel Mystery Oil (~ 5W light oil) in the gas and even into the cylinders for extra lubrication and rust protection.
As previously suggested it would be nice to be able to use non-ethanol tainted gasoline but that is not always possible, easy or cheap (unless you have access to a recreational airfield).
The photo below shows the last gallon or so I pumped out of our 20 gallon fuel tank after nearly 10 years of using E-10 gasoline that mostly sat around. The black stuff on the bottom is mostly water and I'm not even sure if my engine could burn the amber stuff sitting on top.
