Advice Wanted

[raymond1 262]

I have a 17 foot Yorkshire cobble with a yanmar inboard diesel and cooled with a jabsco pump , the pump had a new impeller fitted two years ago and only run for two hours after being fitted

anyway I used the boat last week thinking everything was A1 but the engine over heated ! , I have also heard that pumps left in storage should be lubricated when not in use but what do you lubricate with ? also has anyone an idea how I can make a filter , inline or whatever ?

thanks

does it not have a filter fitted mate? there should be a sea cock, and if you unscrew the lid there will be a tube of gauze in there that may be blocked/corroded? mine was lol i just got some from work and rolled it to the right size and put that in, its done the job for the past 4 years

when I built the boat I forgot to install a filter ,hmmmmm anyway I briefly heard someone say that the impellors needed to be lubricated with gliserene ???

dont know about the gliserene? i just put water pump grease in through the grease nipples? is the pump working at all, as in any water flowing round the engine at all? if not then as you say the impeller may have seized up or if theres no filter fitted maybe a bit of debris, it wont take much to stop the impeller in its tracks or even smash it as they are only plastic, but if its not brocken then you should easyly beable to free it off. as for filters you can buy them at just about any chandlery and its as simple as putting it between a join in the pipe (before the water gets to the impeller) you may need to cut the pipe if there isnt a join but its not a big job.

atb and hope you get it sorted

try something like these, but im sure if you look around you could find something cheaper or maybe salvage something from another old boat if theres a boat yard near you? it doesnt need to be fancy just to keep sh*t out your engine.
