Now that I'm down in my engine compartment... hose clamps.

[MOA_Chaser]

I think while I'm in there, I'm going to start replacing some clamps. There's a bunch of rusty ones down there.

Is there any real reason that I'd need to order Yamaha style clamps, or would I be OK with a bunch of good stainless steel hose clamps?

 

[Andy S]

Stainless steel house clamps would be better than what came with your boat.

 

[MOA_Chaser]

Yeah, I've been reading on TOS and trying to see if the constant tension clamps were worth it. They're EXPENSIVE!

 

[Bruce]

Those look terrible. Making me feel better about the slight rust on mine.

I thought that the Yamaha clamps were supposed to be some kind of fancy clamps that held the correct tension as the hoses expanded and contracted. Certainly stainless steel clamps would be way better than what is there but would new factory clamps be even better?

I replaced everything that was rusty with just good quality stainless steel clamps.

Here is the type I'll change over to when I replace my control cables this fall. I will do some more online shopping to find the best price. I think the weak link with the OEM clamps is the open threads in the bands.

The hose clamps have been an issue for a long time , It is probably best to replace them with high grade stainless clamps and back them up with GOOD cable ties just for that extra security.

At around $4 each, I'd hope they'd be better! There's a lot of clamps in there!

What about using WaveSeal 360 clamps. They are less than $3 each and I believe American made.

There are some out of stock listings on Amazon for closer to $2 a clamp.

At the very least, you want to go with the non-perforated type: http://www.jamestowndistributors.com/userportal/show_product.do?pid=1718

In non-perforated hose clamps, the little slots that the screw rides in are not punched all the way through. This leaves you with more metal and less chance to break.

Not cheap, but neither is sinking your boat...

 

[Gym]

I agree with @biglar155. All of my clamps that broke did so at the slots where the screw rides. I will use either the non perforated or the T clamps on all the hoses. I may reuse my healthy perforated clamps as a back up to the new T clamps.

Would a coating of corrosion x or corrosion x HD prevent future problems?

It might not prevent the eventual failure but it will greatly delay it.

Yamaha calls those things clips.

Prevent? Probably not.
Delay? Certainly.

I've been trying to find a cheaper source for the Yamaha clamps but not had any luck. I even had the local Fastenal store try and track some down with no luck. On those parts of the cooling closest to the intake, the screw type would probably be fine. On other parts where cold/hot expansion occurs, who knows what will happen. What's nice about the yamaha ones is you just slide the new one on, push the hose on, pull the clip, and you're done. No worry about over or under tightening.

My lower clamps are also looking sad and I'm going to need to do something soon just for peace of mind.

 

[MOA_Chaser]

I think for the cost of those clamps, I'm going to evaluate them individually. I have some POR-15 in my garage for a car restoration, I may wire brush some of the clamps and if it's just surface rust, I'll paint them with the POR-15 to stop the rust and seal them.

So I decided to do another fresh search and now I found these:

http://www.amazon.com/6-15mm-Spring..._indust_2?ie=UTF8&refRID=19P2PHKRA4B9F18RAB9X

For zinc plated steel and $3 per 10 (shipped from HK), I'm wondering if these would be worth a shot. Cheap enough to buy one pkg of each.

It's not like the Yamaha ones are stainless steel, most likely they are just regular steel with some coating (if that?).

 

[Gym]

Not sure where you boat @ptwb but I don't think I'd use those in fresh water let alone salt. The Chinese are known for substandard steel and zinc plating is not very durable. The broken OEM clamps I took out of my lower bilge were indeed stainless steel. They all broke where the band is serrated for the worm screw to ride. At those points there is less than 1/16 of material width and it's not up to the stresses delivered to it. Trust me, this is NOT where you want to save your money.

I have not seen stainless steel constant tension clamps from anyone. I ordered 1 of each of the Yamaha clamps various sizes so that I would have the right emergency clamps ready to go and they are not stainless steel.

There are some stainless steel clamps, like the exhaust hoses, and I've had to replace some of those.

I wouldn't be surprised if Yamaha is getting these clips from China. In the end, I've tracked various companies clamps back to RotoClip and just different coatings. RotoClip has a special coating for increased resistance but clamps with that coating I can't find anywhere.

I wish Yamaha or somebody would offer a kit with the right clamps (not the screw type) instead of having to buy tons of them individually.
