Does anyone have any experience/opinions with using a product like LPS-3 (anti corrosion spray) on motors? I wonder if a seawater submerged motor could be cleaned with fresh water then sprayed or doused with something like LPS-3 and live to spin another day.

"The temperature of the entering coolant (seawater) must not exceed 30°C. The circulation of the coolant should be at least 4 litres / minute." The motor will be operating at higher temperatures than that.

While air cooled, it does have forced cooling, and Mastervolt is a large enough global company that reliability should not be as much of a concern as some of the smaller vendors like we regularly see on this group. Here's a photo http://www.mastervolt.com/marine/products/hybridmaster/hybridmaster-96/ and here's a technical drawing of their 4.8kW system http://images.mastervolt.nl/files/hybridmaster48.pdf
