Basically Im going to be mounting my sidepods (which have no bolts and are screwed into the threads in the block) And my water jacket cover which is a nut and bolt combo.<br /><br />I am thinking of dipping each bolt in a high temp corrosion/rust resistant grease before screwing them in so in 5-10 years if need be i can unscrew them (i use my boat in salt water 100%)<br /><br />Do you think this is a good idea or is there something better? <br /><br />I also have this Gasket Maker RTV thing and i have scratched all my covers/pods where the gasket plus the block a bit because of prying and taking the old gasket off. Im thinking of putting the RTV which is resistant to 300deg and has corrosion resistant qualities plug a brand new gasket.. Will this help?<br /><br />Thanks guys BTW my motor is a Mercury 650cc Thunderbolt 1970.. 4 cyl and 65hp

"Gasket Maker RTV"<br /><br />Don't use the copper based hi-temp!!

Wouldn't an "ANTI-SEIZE" compound be a better treatment for the bolt threads?

any preferred brands of the anti seize stuff?<br /><br />So dipping in grease is a no go? I thought it would be ok because its soft and it would fill the threads and when time comes in 10 years i would be able to remove it because no rust has formed :)

use antiseize the grease will harden over time and make the bolts hard to remove

Re: Stainless Steel Bolts/Nuts For mounting waterjacket/sidepods plus gaskets

hello<br /> dont use the copper anti-sieze either. it should be nickel/tin.<br /> it will be a dull grey. I usually use omc triple guard grease or merc special lube 101. neither will ever dry out.<br /> they will be just as nasty 2 years later as the day you installed it.<br />the only use for RTV is as a tub and sink sealant in the house. toss it away on your boat.<br /> do not ever use it where it will come into contact with fuel mix. either in the exhaust or intake side. OMC gel seal or loc-tite gasket maker will seal up to .01". I have seen cases were silicone sealant actually increased the corroision at the aluminium joints. not sure why but I have seen it and it never seals to the aluminium very long.for transfer port and exhaust cover gaskets use omc adhesive M<br /> best stuff in the box. or on intake side use omc gasket sealer, a brown paint on sealant.<br />good luck and keep posting

Rodbolt - about the RTV: You know that eye watering vinegar smell you get from silicone RTV? It's acedic acid, a by-product of the vulcanization, and it eats aluminum good. There's such a thing as 'Electronics grade RTV' that doesn't produce acetic acid (and doesn't have the smell). Not that that has anything to do with outboards...

Re: Stainless Steel Bolts/Nuts For mounting waterjacket/sidepods plus gaskets

Is it just me or did y2j say he was going to use stainless steel bolts??? These will never rust remember. If you are putting a nyloc on the other end of the bolt it is advisable to use a special lubricant as without the nut can jamb half way down with no way of getting it on or off. Go to a specialist bolt shop (Searle Fasteners in Perth) and they'll set you right.<br />Andrew

Re: Stainless Steel Bolts/Nuts For mounting waterjacket/sidepods plus gaskets

Basically the big plates on the side which are 2 part. The first divides and covers the exaust ports the second has circulation of water with a hose leading out of it which is your tell tale :) Thats the side pod.<br /><br />I have this BLUE RTV and it says it has corrosion resistant qualities. Basically it also says you can use it on exuast etc. but i just wanted to use it in a tiny line all around on both sides of the gasket just to fill in the marks i left from the chisel from removing the old gaskets. So i want to use a gasket and the rtv? The guy at the automotive shop recommended this is the best solution for me :/

It only produces Acetic Acid upon curing. When cured it has no residue and I've used it on car waterpumps, Valve covers and all sorts of aluminium fittings with NO PROBS....<br />If there will be water present, any acid discharged will be diluted.<br />GO FOR IT....

Re: Stainless Steel Bolts/Nuts For mounting waterjacket/sidepods plus gaskets

couldn't find any anti seize.. my patience ran away :( <br /><br />So i just used a lithium based hi temp grease which is water resistant for marine purposes.. I just lightly brushed each of the bolts with it before screwing them in<br /><br />Anyway i screwed them in and set my torque wrench to 20 or so pounds .. even though it tells me in the book to do it to 70<br /><br />Anyway turned each bolt hand tight as it says in the manual in the order it also says.<br /><br />Then i started with the torque wrench starting at 20 pounds and to my amazment the heads on the bolts started turning the thread wasn't :( <br /><br />Turns out because i added a gasket sealer which is silicone based and the gasket it didn't want to go that hard. I did manage to remove the broken bolts then i put new ones which i tightened as much i could before the heads started turning..<br /><br />I think its sealed for 2 generations to come with the gasket and sealer<br /><br />Ill show some pics in a minute or 2.. just gotta post em

Re: Stainless Steel Bolts/Nuts For mounting waterjacket/sidepods plus gaskets

Hello<br /> now I know what it is. I think the tech book refers to them as exhaust and transfer port covers. all that blue goo pooching out is also pooching in were it will break off and find a home in a tiny cooling passage. I wish the auto guys would stick to mucking up autos. I wish I had a dollar for every drive that came in the the old blue goo corrosion. it would have been much better to use OMC adhisive M. also I think you may have mistaken inch pounds for foot pounds. I know all the blue goo mechanics that think if a little goo is good a lot is better are going to jump me but the best thing to do with silly cone is to throw it in the trash and use a sealer designed as a marine sealant.<br /> but good luck and keep posting
