Frank said it!
Jerry, I mentioned heat because you said that you tested the cleaning properties of Seafoam by allowing a piston to sit in it. This was not the method that the product was designed. It was designed as an environmentally safe cleaning product which can be burned in the Oil or Gas. It's intended purpose is to be burned. Inside of the oil, it is also coming up to a high temperature to aid it's cleaning.
I did a decarbon on my motor because my compression test yielded only 120PSI on both jugs. That is under the factory spec of 140-160psi so it was my hail marry to attempt to raise it. I have not ran a test since that day to see if it made any difference because I'm too busy using the snot out of this boat.
I do agree with Frank about an engine not needing it. Our Ethanol gas help us keep things clean by adding 10% alcohol to our fuel. That is far more PPM than any cleaner we purchase and put in the tank. Not to say that 10% doesn't cause other issues such as moisture attraction and go stale in 30 days.
With all that said, I have never had an issue with our E10 gas in any engine. I use marine stabil for my generator fuel which I allow to sit 1 year before throwing in the truck to burn and it runs the same on day 366. GRANTED, I run the carb dry while its being stored.
Being in Texas, I can boat year around so I do not require the use of Stabil in my boats fuel. I have tried running it at in season use dosage (1/2 of storage dosage), and noticed it would foul up my plugs with extended trolling and smoked a whole lot more. My carb rebuild (just because I wanted something to do) looked like a brand new carb. Shiny as the day it was born.
I honestly do not see any manufacture advising a decarbon procedure. Yamaha recommends using their high dollar additive year round, this seems more like a money making scam to me.... The sprayfoam did something because my engine puked out tons of black sh*t all over the driveway and down the side of the Lower Unit.
I have attached some picture during a ring change that I did on my model airplanes 55cc 2 stroke engine. This is a 5.5 HP 7500 RPM motor that gets pure abuse. On the throttle, off the throttle. Prolonged wide open 7500 rpm runs, minutes of hanging plane on its nose with zero airflow over the fins. I've never over heated this engine or has a lick of problems. 3 years and over 300+ hours of this, the inside looks like shown. I only tore engine apart to install boisen reeds and a new ring.
