I was just going through my weekly check on the ABNB brokerage site and they have a very nice boat for sale NB Kingfisher
What caught my attention however was the engine hours 9,954!
I have been working on boats and selling boat parts and engines here in Sydney for the last 30 years. The majority of diesel motors in the 40hp range are lucky to reach 2,500 hours. Very occasionally they get up to the 5000 hour mark but are well and truly scrap value!
And the reason for this......here in Australia they are running in a saltwater environment , sucking in salty air really does stuff them very quickly no matter how many air filter systems you put on them, plus sucking up salt water through the cooling system. Another reason is they are running at much higher revs 3000-4000 RPM.
Whereas the average narrow boat diesel plodding along at 1500rpm or charging batteries and running a closed fresh water system is going to last a lifetime. It would be interesting to know how many hours some of the long term continuous cruisers are up to?
