Sealine S24 Kad32 DPE Outdrive - Geeting Antifreeze into seawater System

Bigplumbs said:
Bruce you may have missed one of my questions as the thread moved on somewhat.

So that I can make up a pipe prior to going to the boat (It is some way from me) do you know what the dia of the inlet pipe at the water pump would be ?. Searching the net cant seem to find this out

Thanks

I honestly cant remember. It was several years ago I bought the hose for it. I'm sure it's 25mm but dont curse me if I'm wrong and you dont have corroboration.

If the boats on a trailer just place a suitable container full of the liquid of your choice under the leg covering the inlet grills .
Start up and let it tick over for a bit until ( if different colour - ie green AF ? ) it’s all circulated through.
If poss a big enough container to submerge the exhaust in the interest of neighbourly behaviour.
No need to touch a jubilee clip .
This is what I see at dry stack operations.

You would need a big container to cover a DP Drive and you would use a heck of a lot of Antifreeze me thinks
 
Look up under the the casing below the water in take grills and you will see another small inlet that needs closing prior to start up otherwise this will draw air and no suction

That is interesting. I have ordered a pair with straight edges and a flexible inlet to see if I can get them on the drive as I would prefer this method

I did the same but they simply wouldn’t work - just couldn’t get the engine to pull the anti-freeze through so ended up using the pipe to the intake on the raw water pump and bucket method.

i have permanently tied my muffs together on the forward edge and pull them aft with bit of temporary string, wooden bung in the bottom, takes seconds to tie it on when set up.
add hose pressure, no problem rinsing the system at all.

Where did you stand the Bucket of water because I have very little space in the engine bay of the Sealine S24. Or did you use a long hose and stand it on say the swim platform

It was sort of wedged between the hot water tank and the alternator.

Yes I found the same as you. Cured this by gravity feeding antifreeze mix to muffs through a short length of pipe and funnel.
Also used a large container to collect antifreeze as it exited sterndrive. Of coorse you need a second person to start /stop the engine!

putting AF in, why not just take the lid off the water strainer and poor it in direct with the KAD running ?
only for min or so, not going to overheat, or will it all splat out ?!

The impellor is on the intake side so it doesnt work i.e. nothing to push it through the sytem with the strainer lid off.
 
Many thanks for all the input. It would appear that for quite a simple and job that is probably carried out by many people some are doing it one way and others another way, Some not at all and some doing ti but not realising that perhaps they are not doing it properly

Well done volvo for making it so clear and of course making it easy...….. :)

I owned an S24 with a KAD32 for several years.
Hose thing plus a bucket of antifreeze worked a treat.
Doing it another way by draining everything is an equally valid approach, but it can be tricky to find the drain points,
Your choice.

Thanks Flower Power. The thing I am finding very hard is to find out the internal diameter of the hose that connects to the bottom of the in on the strainer housing so I can make up a pipe thing.

I think it is either 1.25 or 1.5 Inch..... Asked a volvo dealer and been all over the net no one seems to know

on a KAD 44 it is 32mm external diameter of the in / out pipe, just measured it on the old spare pump at home.

Thanks Simon that is very useful. I have bought a 32 and a 38 so should have it covered, assuming it is the same size on a KAD 32

just checked with 32mm braided hose, well that does not go over the lip of the inlet, not even on the workbench
might go if i heat it up, but that is extra 'fun' i can do without on the boat
so stretchy rubber hose 32mm internal or bigger is needed ....
