dimples

Not the bolt Aussie, they came out ok..it was the anode that broke. I'd love to take it to Huey mate but I have more time than I do coin at the moment so I'm just trying see what I can do myself to find the missing pieces (assuming they r still there).If I have no luck with it I'll book it in...last thing I want is to be stuck outside somewhere with an overheating motor Thanks for all the help guys appreciate it

Mine is splined at the top & fits in like the drive shaft,only thing I had to do was unscrew the nut on speedo cable. I found several pieces down there thanks Fab1. I'm still missing around a blades worth of rubber,so I removed the thermostat & thought I'd put the garden hose in there to back flush,strong hard waterflow coming out of the watertube but no sign of rubber pieces in the water drum. Someone suggested I remove the 4 pencil anodes from the head & try to blow out any pieces with the airgun or flush out with water. I removed the top 3 without any probs but the bottom anode broke (of course),snapped flush with the face so I cant get pliers on it,so I'm debating whether to leave it in & let it corrode away or risk pushing it through by drilling & using an easyout.

That's good advice Incredible,Well I took the pump housing off & found the impellor destroyed (took a pic but don't know how to post it) Worst thing is half the rubber is missing

Hi achjimmy thank's for the reply,I removed the thermostat cover & held it in the open position whilst running the motor for 30 seconds..not a drop from there.

Hi Raiders,I have an 02' 60hp 4 stroke yamaha which i don't use often (twice since i bought it in Jan) but i do give it a 10 min flush around every 3 weeks. Yesterday I tried it & no water coming out of telltale,checked for blockage in telltale hose & ran it again in a large drum still no water but there is a bit of air pressure coming out. My question is can an impeller/waterpump be worn even though it's pumping air out of the telltale or could it be something else like a frozen thermostat? Service receipts say the impeller was replaced 19 months ago. Thanks.

Nice kingy dave, well done
