Any recommendations on which brand of fuel system cleaner, fuel conditioner/injector cleaner is best to run through a 2005 4.3Gxi Volvo Penta engines with 135 hrs each which have been maintenance starved by previous owner? The boat is a 2006 288 Vista. Thanks for your consideration

Do you have blocked injectors, or is this preventative maintenance?
Most injector cleaners are made with the same ingredients, so buy a reputable branded one.
Note that these will contaminate your oil somewhat.
Most would not, but I'd suggest you use this close to an oil change.

Nothing you put in the gas tank from a can will make any difference if they are gummed up/clogged/or not firing right.

It's cheaper to buy new ones than have them professionally cleaned. They're just Bosch EV1 style injectors, probably the most common fuel injector in the world. Nothing fancy. They should be 24# or 250cc rated. Buy a new set of 8 for around $150 shipped. I think directly from Volvo/Mercruiser they want like $300 each!!!! Gotta love it.
