Just in the process of re-furbishing the
water pumps on our 6 year old
lagoon 380. Sea
water has been leaking from the pumps and they are in a right old mess as you can see. The clean one was soaked in citric acid solution and then a light wire brushing. New pumps are about £400 each... the
parts to do a full re-furb cost about £40 !! so a big saving. Bearings cost a fortune from
Yanmar, but standard
stainless steel replacements are about £5 each ( and the
Yanmar ones are not even stainless )
