Aluminum vs steel freeze plugs

[Mark100]

Can I use steel instead of aluminum for the 1 1/8 inch plugs in the Seadoo tune pipe(exhaust). I found them at the local auto part store.

I'd say no, because of the issue welding disimular metals.

Didn’t someone on here have one that used a quarter and JB Weld? [emoji23]

They found his jet ski at the bottom of the lake! Lol.

Anyone know where I could get aluminum ones?

OSD and @racerxxx I think sells them.

Thanks

I make them. In stock and will ship tomorrow. $5 each and $7 priority shipping in that lower 48.


Seadoo 720/787 Welch plugs, Exhaust plug/cap or whatever you want to call them.......

Steel is fine for a car and brass and bronze are dissimilar with alumuinum as well so don't play well with alumunum either. However, in a marine cast iron manifold or block, they are the material of choice.

Not that this applies here but just an FWIW so if you ever do run into a leaking freeze plug in another future or galaxy beyond aluminum manifolds, you're aware.

A steel plug in aluminum might be ok in fresh water (*maybe*),
but would definitely set you up for galvanic corrosion in salt water.

Just so everyone is clear these are weld on plugs/cap. So steel is 100% out.

 

[mikidymac]

Wait! So you’re saying you can’t weld steel to aluminum? WTF!

I think some people were thinking (possibly, an assumption on my part) they're like a automotive freeze plug that taps in. Soooooooo, I posted a pic so we're all clear and someone doesn't go and buy a steel or brass freeze plug and walk into the welders shop and ask to have it welded on. And look like a total knuckle head not knowing it can't be done. That's all, just a little, small, minute detail that I didn't want overlooked. Not everyone knows.

And before anyone gets upset, I'm not inferring or implying anyone posting on this thread is a knuckle head.

A friend of mine welds vacuum tight ceramic and stainless fittings, I've watched him weld two bricks together.

Despite not having a current JB welders certification, I can weld two pieces of toilet paper together! No, don't ask!

Oh come on, where's your sense of challenge and adventure?

I think he's saying his aluminum cannot be welded to steel or brass?

It's just irrelevant information potentially confusing someone not in the know coming here for help and walks away unsure, possibly down the road in a year or three.
