Ouch! Well there we have it in my case!

So are you guys thinking it might be a good idea to yank the injectors and have them looked at every 150-200 hours?

I have 6.2's in my 292 with 320 hours. They run as strong and smooth as day one. At least every other tank full of fuel I treat the fuel with MerCruiser Quickleen or SeaFoam. If the fuel will be sitting a while I alway use a fuel stabilizer. So IMO if you keep up with the fuel treatment there should be no need to pull injectors.

Injector cleaners containing PEA, will keep injectors very clean. GM and BMW did a study some time ago. A point to note is most available cleaners contain zero PEA. Redline Fuel system cleaner, Amsoil and REGANE(the expensive one) all contain a healthy dose of this very effective detergent.

If you ask me, yeah it's a hell of a lot cheaper than my engine builds. I wish I would have done it when I got the boat with 130 hours. Looking back on it, I think it probably needed it that early. We are planning on having it be an every other year item. It's cheap insurance.

I ran SeaFoam and it still happened to me. I won't be using it anymore and I'll just be pulling the injectors every couple years to be extra safe.

What company's are recommended?..... From what I found on the net.... After the first time you will know if it was needed. Most provide befor and after data

Sea foam is not good at cleaning fuel injectors. Contains ZERO PEA. I'm not surprised you noticed nothing. I've studied these chemicals and have seen the results. Head over to bobistheoilguy to read up on the fuel injector cleaners that deliver what they promise. Need to get past the hype and check out the science. Companies don't like PEA because it's expensive. There is no other more effective cleaner for said use. Everything else is just solvent.

Companies that use PEA are : Redline oil, Amsoil, Regane(their top tier product). Chevron techron(expensive concentrated formula).

PEA also cleans valves and combustion chambers very well as it is a high temperature detergent.

I'll keep that in mind for sure, but I won't be putting all my faith in anything from a bottle after this. Can't hurt to run it on occasion though! How often are you running it?

Scott Sjogren (at Pier 57 where purchased my Fountain) suggested running ValvTech fuel additive full-time. It really adds very little to the overall cost of running the boat. I have also used Chevron Techron in my Corvettes, truck, and (yes it is a bit embarrassing to admit) the Prius. When the tank gets close to 1/2 I add 5-6 bottles of Chevron Techron to the boat once per year. So far, so good. BTW - Scott's opinion is the 6.2s should get at least 850 hours before needing a refresh.

I run it in all of my cars and trucks, as well as my two boats. Use it about every 3rd tank. The companies that produce it usually will recommend adding a bottle once your tank is near empty and then filling up after the bottle is dispensed. Remember, we are talking PEA for removal of deposits, PEA isn't a miracle worker that will remove debris from screens inside the injector or repair worn passages. Ethanol or not, injectors get dirty. Plenty of studies out there show that certain cleaners will keep injectors clean for their given usable life. I do not own a scorpion motor, but that's besides the point as we are discussing gasoline fuel injectors. An $8 bottle of injector cleaner is pretty cheap insurance in my book.
