Hello, Seeking advice on best practices for months or possibly years of out of seawater storage of 150hp four stroke outboard engines. Six Yamaha and six Honda engines used in tropical saltwater environment for 2 years in a disaster response program. Vessels and engines now need to be stored in readiness until next disaster (usually typhoon) event. Are the standard winterizing/long-term storage procedures still effective in this situation? Ie: Can we be sure o-rings, seals, gaskets, etc. will not be cracking/leaking after possibly years of tropical conditions storage and not running regularly? Or better to set up monthly schedule of running engines with freshwater cooling supply?
