Many of my friends fush their outboard petrol engines with fresh water after every use in saltwater.
My engine - volvo 2030 with raw water, heat exchanger and fresh water 'internal' cooling. Would I help extend the life of my engine if I fitted a Y valve to the raw water intake before the pump so that I could hook up a fresh water hose and flush out the salt every now and then? I understand that the outboards need it more as they are entirely salt water cooled but I thought that by flushing I could help my engine last longer.
Has anyone tries this? Is it worth it? or am I being over protective of my pride and joy?? PS my boat is in arabian gulf so very salty!
