Sikaflex over windlass motor terminals

[Simi 60]

Installing the new motor in windlass tonight.
Previously they were sealed with liquid PVC after tightening.

Opens can of liquid PVC and it's solid, not about to buy another on short notice.

If I assemble using noalox, is there any real reason why a smear of Sikaflex over the top to keep any moisture out won't work?

I have that onboard and opened.

Can you get some adhesive lined shrink tube on the connections?

No

I guess that the Sika, while it may not stick to the coating, could be taken off if it doesn’t stick well. I have had good success with Boeshield on battery terminals.

Just grease them. you have dielectric grease on board right?

I agree, dielectric grease. And if the connections are in a reasonably well sealed motor housing (like the Maxwell horizontal units I'm familiar with), it shouldn't take much to keep the connections clean, as they shouldn't ever directly get wet.

So no one has a reason why not?
So sikaflex it is.

Nope, never had it on any boat I have been on over the past 40+ years.

Good idea. Please post with results. I have some open terminals that I'd like to cover.

Greetings,
Mr. S. 2 reasons to not use Sikaflex:

1) It is opaque. IF any corrosion occurs underneath the coating, you may not detect it.
2) One less thing to have to deal with on disassembly.


A coat of ANY grease would be better IMO. Easy to monitor the condition of the terminal and cheap/easy to re-apply.

But it's not easy to unbolt and remove 208 lb of windlass from the deck to inspect
Trowel it on, seal it shut and easy enough to pick off the lump at a later stage.

Jobs done, in between rain showers, last bolt cranked down as it went torrential.
Expected severe weather this afternoon so no choice but to run with what he have at hand..

Liquid PVC would have been my first choice
But
Sometimes we have to Mcguyver an alternative.
Can't carry everything all the time.

Sure would value an update in the future, success or regrets.
