SUBJECT: OMC ACCESSORIES ENGINE CLEANER

OMC ACCESSORIES ENGINE CLEANER is an internal engine cleaner designed to clean piston tops, ring grooves, and cylinder walls of engines that are moderately coated with petroleum gum and varnish without having to dismantle the powerhead.

The necessity for having a good internal engine cleaner becomes evident when remembering that under certain conditions it is possible for pistons and cylinder walls to accumulate a thin coating of petroleum gum or varnish. These gum and varnish substances are rather sticky, which, over a period of time and for no apparent reason, result in excessive piston drag and ring to piston seizure. The overall result is sluggish engine performance as evidenced by gradual R.P.M. loss. In extreme cases, complete piston to bore seizure results, particularly after periods of storage.

Therefore, when looking for a satisfactory and time saving method to remove much of this gum and varnish without having to tear down the engine, OMC ACCESSORIES ENGINE CLEANER is recommended. It should be noted, however, that this is a CLEANER, not a preventative, and must be used in strict accordance with the instructions on the container.
