Water stopped squirting from spout and started coming out of mount area

Fired upbeat the motor from my first rib yesterday.. Started immediately and sounds good..

I monitored the water spout which came out after a free seconds and ran OK.. Then it started dribbling and then water started coming out of the area in the pic..

How do I fix it? Impeller is 5 months old and hardly worked..



This is a 1989 mariner mercury split case 60hp 3 cylinder..

Is this the serial number?

Looks like 1593 7511C2



Thanks

cheers

it was done by the PO who had it or a few yrs.. im sure they would have done it correctly.. the water was coming out at the top for about 3 minutes.. then it started dribbling (dirt?) and then started coming out the mount -

it seems like there must have been dirt in there cos it was working fine.. and the water was warm .. when i followed the tube up the motor it went ontop of the top cylinder on the head.. so it was circulating thru the head..

the motor has some rusted nuts so im quite sure its dirt / corrosion..

how to i flush this out?

with the water coming out between the head and stem sections it looks like a decent tear down?

yep looks like a bigger job possibly blocked up with corrosion.

curious why it wd be coming out at the base of the head section - seems super odd.. i was half keen to replace all te rusty nuts and bolts anyway - oh well.. my guess is the incoming hose that connects to the lower section of the head prob came loose / split and now its running down the inside instead of circulating up through the head -

possibly i would start by taking the lower unit off look at the pump, back flush from the tell tale, maybe your right re the hose/pipe, split/corroded/ loose taking the leg off not a big job it might be quite simple and revel the problem.

yeah tx - those bolts holding the shaft up are in bad shape - prob good to take the lower unit off and shaft - and give everything a once over..

thank goodness the motor fires up instantly without choke on a cool day - those electronics look incredibly complicated..

re the bolts there was a thread on here from Dan gurney taking bolts out to change engine mounts on a yam he had them break off very easily then it become a major job best of luck.

Id have to get between the head and the shaft section -

take the gearbox off first then decide have a look up the leg with a torch you might see the problem without going any further.
you-tube is a good place to start see if anyone has any tips on stripping your engine or any engine gives you an idea D-ray's for one, guy in the south of USA has some good tips fitting water pumps/servicing etc.see if you can download a service/workshop manual i think there's some on here not sure where to look but a bit of searching will come up with something but d-ray's a good start you absorb it better when on a video.

cheers
