3ltr opti hose tails to exhaust plate

[gtflash]

Trying to remove the hose tails that go down to exhaust plate on my 2000 200 opti. the dealer who sold the part, said they are a pig and snap off and in fact they have. The originals are a brass threaded unit and a 19mm socket fits them to undo(if they dont snap). The new units are a composite thing and mercury part number 22-858855.

Ive tried an easyout but didnt work, so left them soaking overnight in WD-40. Any help please?

WD-40's carrier evaporates. If you have something like PB-Blaster, it may help to soak it in that stuff for a while (or any other Liquid Wrench type stuff.)

Other things you can try: Heat the snot out of the area (make sure there aren't any other plastic or rubber parts nearby that will be harmed), then freeze the plug remainder (spray freeze should be available at an electronics shop - if not, a can of Dust-Off turned upside-down will work, too), then try an appropriately sized EZ out. The cooling may shrink the part enough to break the corrosion.

On this side of the pond, some people swear by melting candle wax onto frozen fasteners and heating the area to get the wax to lube things up. This trick has never worked for me, but maybe it will for you?

You may have to resort to drilling the wall thickness of the stubs down, and picking the threads out. I would use this as a last resort.

More experienced mechanics may have better options for you.

they are a pig to get out, unfortunutly only patience will do, cut with a hacksaw blade and carefully chip away GOOD LUCK

thanks guys. I agree I think thats my only option.... See you in a few weeks. I presume the exit of those holes is down th impeller?? SO ill have to guard the swarf?

[uncle al]

yes catch as much swarf as possible if you are carefull you will catch most of it

ALL done. Tops ground off to break the rust seal, heat and easy outs, with torque and impact. Toook 4 hours and 3 blisters. Also has a loctite on the originals which helped cause missery.

Thanks all for help.
