Broke plastic part. Can I glue it?

[Saskatoon2005]

Hello all, I have a plastic broken piece from a 1973 Mercury 7.5 H.p.. The part comes from the throttle control linkage. It is a major part and I was wondering if there is any product out there that will "glue" it back together and make it as strong as it ever was?<br /><br />Thanks all for your help!

I broke the plastic linkage on my 9.8hp. Tried epoxy and it did not work. It was the linkage between the rotating throttle point and the timing/throttle advance arm under the flywheel.<br /><br />Probably easier just to replace it.

Yeah, if I could replace it I would but i can't find out where to locate the throttle linkage for my mercury! Anyone have any ideas? The part number is 63697A1 LEVER, THROTTLE CONTROL!

The glue or epoxy will let go when you need it most.

Can it be manufactured out of aluminum?

Probably yes. Also try the Mercury NLA hotline. I misplaced the number but your dealer or someone here outta have it.<br /><br />-W

Well the part I require is off of a 1973 Mercury 7.5 H.P. outboard. The original part number is #60860 and then it turned into part number #63697A1 before finally becomming No Longer Available. This part is the throttle linkage part joining the turning throttle handle to the moving megneto that is under the flywheel. It is also found on 9.8 H.P. Mercurys as well.<br /><br />Check this out...<br /><br /> http://www.sandslave.com/merc/index.html

What is the Mercury NLA hotline? I would love to get that so I could buy this much needed part! Please help me out Clams Canino!

Thats exactly the same part that broke on mine, and in the same place.

So what did you do AMD Rules? What should I do to fix this problem? I am at my wits end!

Will p/n 66374A 2 LEVER ASSEMBLY, THROTTLE CONTROL work? Looks like it is still available, but pretty expensive.<br /><br />You may be able to get parts locally from TMD. themarinedoctor.com check him out.

Hey, where can I see a picture of that part? I don't really care as long as I can get back on the water come melt off! Thanks for you help so far as well. I really appreciate it as well.

Hey Saskatoon,<br />If you have the skills to fabricate this out of aluminum, why not? Seems like a good idea to me. Either use the plastic part to make a mold and cast it or machine it out of billet. Then it won't break again!<br /><br />I am baffled that there is so much plastic in the linkage on my 1976 Merc 200, where my 1962 110 linkages are all metal. Some parts on mine were so worn it could not be adjust properly.<br /><br />I find most of my spare parts on eBay, and have picked up some spare linkage parts for mine and replaced the worst ones. Sorry, don't have the part you need but if I see it I'll ping ya.

Re: Broke plastic part. Can I glue it?

One other thought. Could you glue this to hold it together, then drill a vertical row of very small holes in the cam on one side and the arm on the other side, then thread fine steel wire through these holes, winding the wire around the repaired cylindrical part to reinforce your repair, then coat the outide of the wires and the repaired part with a layer of JB Weld? Maybe this is crazy, but I think I would try it if I had no other options. Then I'd keep looking for a replacement part on eBay. But if the original part has a fundamental design flaw you may have to think out of the box.

Plastic glues (that work) are hard to come by especially for high-density polyethylenes. If you want to repair it, I recommend welding it. I bought a Mini Weld 5500HT from Arizona Tools for under $150.00 and used it to repair agricultural MacroBins and the welds are holding up with 3000 lbs. of grapes in the bins. The kit comes with welding rod and comprehensive instructions.

Re: Broke plastic part. Can I glue it?

Hey PuckHog,<br /> I just researched your information that you told me about and found a local automotive supplier to body shops who promises that a special urethane glue will "do the job". It comes in a two tube syringe type applicator. I asked him if it was like epoxy because I was sure that it would not work and he assured me that it was in no way like epoxy. It was formulated to seal plastics and after I read about your Mini Weld, I learned that the same type of "urethane" is used to weld plastic together. ..and at $48.00 a tube of this stuff, It better work...LOL!<br /> I will let you guys know how it turns out though so everyone will learn about fixing there own plastics.

Also check with a local hobby shop. I build RC aircraft as one of my hobbys. A lot of plastic is used now days and they make many glues for it now.<br />Plastizap is the name of one that I know of also there is others some weld the plastic together. Take your part with you to the hobby shop and they may can tell you what will do the best job for you. Good Luck, Tim

Re: Broke plastic part. Can I glue it?

I'll try that if the other does not work, and thanks for your input...I love when a lot of people get together and try to solve a problem...you know the old saying," two heads are better than one!" That's why I love this forum so much! Take care and I'll let you knwo how it works out

Re: Broke plastic part. Can I glue it?

Sask2005, do you know what type of plastic that is? You could try solvent bonding if it is a compatible material. With the right combination of plastic and solvent the repairs can be as strong as the parent material.<br /><br />On a different tact, I have come across a glue that is superior to anything I have used before. Its called 'The last glue' and I would describe it as a sort of Super Superglue. Just started using it and have found it MUCH superior to anything I've used before. May or maynot be compatible in your situation, but generally the better the fit between the two pieces the better the bond.

Re: Broke plastic part. Can I glue it?

Saskatoon - you've probably already explored this option, but it's often worth while exploring the bone yards of boat dealers. The pile of junked engines they have out back, etc. There's a million 9.8's and 7.5's of that vintage out there, and you might find a part on one. Good luck anyway, and please tell us how that adhesive works if you try it.
