OUTBOARD REPAIRS

[NQCairns]

Hey Dr Dan the mechanic is just going to pop the cyl heads/covers, you might as well do it yourself, he is also going to tell you that you need a full teardown as well, might as well do it yourself? if you have a go take heaps of pics for memory and check out the manual from the library. nq

Hey NQ you got any bright ideas on pulling out bolts out of the head that just want to snap leaving an embedded bolt with no head? I'm looking at the prospect of drilling and using ezi outs on every bloody bolt on a really old engine. (alternative is to just let the old beast die a graceful death.

I'd be happy to take a note of those cheap spare parts shops in the US you dicussed earlier.

If you have access to oxy acetlane, with a No 12 welding tip, heat the head of the bolts as hot as you can get them so the heat travels the lenth of the bolt, taking care not to over heat the aliminum, when hot, quench the block and head with water to quick cool. This process will expaned the bolts a franction by the heat and the quick cooling will shrink the aliminum, DO NOT ATTEMPT TO UNDO BOLTS WHILE HOT, After you have done this with all bolts, spray with crc etc and leave it untill completely cold (couple hours) then procede to undo bolts by slowly working back and foward
Bloody long winded i know, but with care and patience, they will all come undone, may have to repeat the procedure on some bolts
cheers

Hi Burley Boy i feel for you I really do, many times I have done the tantrum (spit the dummy) dance over a broke bolt because I am no chop with the oxy like blaze's best practice suggestion.
Very often if after all the bolts are out or broke the cover they were holding can come of and reveal the broken stubs a pair of vice grips and penetrating oil + some gentle heat can work over a few days also welding another piece of metal to the stub also is a help for purchase, for some reason the weak link is always at the bolthead the broken shaft can be torqued at least a bit higher.
Good luck you will get there I am sure.
I will chase up some of the US sites soon and PM.

So blaze, [smiley=idea.gif] really I could have poured cold water over the engine just after the second time my mate tells me it "stopped" for some unknown reason.
It must have been damn near close to hot enough as he'd melted each of the three coils down to a molten blob and there was no paint left on the head.

Thanks for the tips and apologies if someone feels I hijacked the conversation.

Don't mind others joining in on the conversation. Always interesting to hear others problems!

Was fishing in hinchinbrook last week, and the motor started to "sound funny". The revs started to die, it felt like it was struggling. Looked around and it wasn't pumping any water, so killed it straight away. Was pretty hot. Took the cowel off, a bit of smoke coming off the head (does this sound like technical terms???!?!?!?!) Left it for a bit, but couldn't get it re-started. Just wouldn't kick at all. Tried it yesterday, started first pull, but still isn't pumping any water. So...... my guess is, HOPEFULLY i haven't done too much damage to it, just going to be a minor job to fix it.

WOuld also like to know enough to do minor maintenance occasionally so HOPEFULLY it doesn't have me stranded too often!
