Flushing unloved motor

[Andersschroder]

Hey guys. I bought a superjet recently without knowing exactly what to look for and as it turns out the previous owner has never washed the engine exterior when sailing in salt water. He has flushed it internally though, phew, so he say. But who know whats he has and hasn't done.

Lets say that there is as much salt build up internally as there currently is externally. Whats the best way to get all the salt crust off inside? i know that Salt Away is good for regular usage but it doesn't seem strong enough when i apply it, to remove the salt caking on the exterior of the motor.

Any ideas?

high speed lake runs will be great if you have a lake close by. the fresh water combined with fast flow rate and engine heat will blow out and break up all internal residue. then flush regularly with simple green or glass cleaner with the flush mixing kit. the ammonia in glass cleaner will really assist in breaking up internal salt. if you choose to use straight ammonia make sure you dilute to at least a 2:1 water ratio due to the pure strength may eat through gaskets and exhaust couplers. you can easily detect how bad the gunk inside is by your overboard pisser strength flow rate while riding.

Water is the natural solvent. Sodium chloride is soluble in water. Add engine heat, and even more so. Salt ions are positively charged. To attract salt ions, a negatively charged additive will be needed.
Water will do it over time. Most dissolved solids in water (fresh) are negatively charged.
This is why salt or potassium are used in softening systems for drinking water.
Keep an eye/ear on that starter. It's difficult to rinse, even for somebody trying hard.
