i have an old (old old old) mk3 manual bilge pump
on my (no longer new to me) boat
. it's oval shaped with a lever tightening the front access plate, type P7/L MKIII. it no longer works - and i bet hasn't in a long time.
i contacted Whale Pumps and it's a model they discontinued many years ago (we knew that), and they couldn't point me to place where i could buy the kit, just said they believed the current
(mk5) model uses the same diaphragm
, and steered me away from making my own flapper valves (which i believe are the problem).
i searched the forum and didn't find much. any recommendations? i remember reading the mounting patterns are different between the mk3 and mk5 - so even if i were to buy a new mk5 i'm not convinced it's a drop-in replacement, and i have enough projects on my hands as it is. is anything they sell today - like Whale Spares Kit
- going to fit?
