Mercury 4 Stroke Oil Drain Valve
Did a service on the '17 Mercury 150 on Saturday. Found the oil drain valve to be seized with plenty of salt build up.
I opened it up with a breaker bar but found one of the three o'ring had picked up/was damaged. Being Saturday afternoon that put a holt to Sunday fishing plans with the young fella...
None of the major mercury dealers carry the o'rings in WA. After a little bit of googling i found a US website the cross matched the Mercury part number with the actual o'ring size in the description #winning.
Quick trip down to Hallite and i now have a full set of o'ring/seals for the oil drain valve.
Problem is $10minimum and only $2 worth of items... So if any FW members with a new merc who do their own servicing suffer the same fate, I’ve got 4 spare sets of seals kicking around my garage.

Couldn't fit from a kit?
I have a couple of o'ring kits from Hare and Forbes, cheap and seem to cover most emergencies, seeing as I am sorta remote.

Did an o-ring on the oil pump
Did an o-ring on the oil pump on my outboard, Evinrude didnt make the part and only supplied new pumps (fu*n piece of shit etec's), stripped it down, removed o-ring, whipped over to a seal place in Wangarra, they measured up and made me one for free using oil resistant material.
Wish I could remember their name but there are certainly alternatives out there to get you going again.

Yes mine was close to seized
Yes mine was close to seized the first time I did mine too. Removed it completely and used anitseize to re-assemble. I actually have a silicon rubber cap over mine now to keep the salt out.
Keep a close eye on corrosion around the thermostat housing too mine was starting to corrode there too, I take it off every service now to inspect..
I'm less than impressed with Mercury parts service, I'm now waiting 6 weeks for engine mount blots which sheared off....

I pulled the thermostat
I pulled the thermostat too.
Spotless inside but a fair amount of salt buildup around the seal face.
Gave it a good cleanup and reassembled with a liberal dose of marine grease.
Most of my genuine parts will be coming from the net

Anti seize
An outboard mechanic told me a long time ago never to use anti seize on an outboard as it contains metal that reacts with aluminium.
