Any experience with the injector cleaners online?

Idled fine, would not get on plane. Drained all old fuel, replaced fuel sending unit (top was corroded), added F/W separator using Yamaha filter (did not exist prior), cleaned fuel rail, and tried to blow off injectors and changed spark plugs, measured fuel rail pressures ....finally borrowed four injectors from a friends boat, and miracles do happen. The boat ran perfect. Put my old injectors back in and, yep runs like crap.

I am sure the basic rules apply. Replace old gas, add a f/w filter in addition to the E-85 additives, and finally use that boat often.

Flagship Marine will clean,test and ship those injectors back to you in remarkable time at reasonable rates compared to replacement.They have'nt failed me yet.

I agree with HonDon, however I hope your not running E-85 ae your engine will puke on it.

Use Flagship, get rid of the E-85. The engine is not designed to run on anything less that e-10 (E-85 is 15 % ethanol).

Change all the filters and drain/inspect/clean the vapor separator tank.

Do a search on "F115 bogging down"

E10 is 10% ethanol by volume per gallon of fuel.
E 85 is 85% ethanol per gallon of fuel by volume.
there is legislation pending to increase the federal mandate to E 15.
currently there are no US marine market engines that run or can run on e 10.
unless you consider the BRP flex fuel 200 and 50 hp engines but at 25K and 11K I would not consider them at this time.
