Moeller 099081-00 Adjustable Inboard Motor Flusher

This flusher worked for winterizing and changing the oil on my v-drive inboard (2005 Super Air Nautique). However, the raw water input is not located on a flat part of the hull, so this flusher does not form a complete seal on my boat. That said, I can still get enough water into the cooling system to run the boat at an idle. I would avoid ever running on this flusher at anything more than idle rpms. For under $25, this flusher gets the job done with simplicity. I would recommend it for inboard boat owners.
