3.0l mercruiser 99 bayliner starter bolt broke off

Any luck?

Actually it is better to take the negative off first, then you don't need to worry about the wrench hitting something when you take the positive off.

But yes - I agree that you need to drop the starter and see what you have left. The good news is the piece remaining is usually not in the block very tight.

beat me to it... First and last battery terminal you should touch is ALWAYS the negative... Doesn't matter much in a boat but it will save your bacon in the automotive world.

I am attempting today so I will let you know how it goes and post some pics when done

I was unable to get it out I think I'm just Gona use some epoxy any try n stick the broke bolt in there at Least the other one is still secure ! I kept breaking bits tryna drill a hole none were successful

 

[Masarudizz]

Might try again some more another day but after 3 hrs of sweating in the hot sun I gave up for the day

 

[Masarudizz]

I just don't want more problems then I already have and the boat works with jus one at least

That's frustrating and walking away for a night is a good thing so you can clear your head and adjust your approach. Biggest thing right now is DON'T PANIC. You can do this. Good news was that you were able to get to it. Was it broke off flush? recessed a little, or even sticking up a little? You might call a mobile weld guy or take it to a welder and see if they could tack a nut onto the part still in the block. This would let you unthread it just like a normal bolt. I would be surprised that the remaining piece would take much force to remove.

Are you positive it's not sticking out of the block? If it is, it might be very easy to remove with some vise grips. You would have to remove the starter though.

Personally, I would be pretty nervous about the other bolt breaking using the boat this way. It would be even a bigger pain with two broken bolts. On that note, after you get this fixed, I would replace the good bolt too, as it has been under quite a bit of stress while holding the starter by itself.

You'll get it

Might be worth setting up some shade and a fan. It's frustrating work by itself-sweating the whole time just makes it worse

 

[Masarudizz]

It's in there deep no vise grips will work I might jus try the fan idea and see about spraying some wd 40 up in there maybe that will help but the problem is once I put the drill there to drill the hole I can't see at all I'm jus guessing and the center punch didn't work I bought one and tryed but I am scared I'm Gona drill into the block or crack it then have more problems ? Or be even more worse off then I am

It may sound like a lot of work, but to me it would be far easier to pull the engine and put it on a stand.

 

[Masarudizz]

I've never worked on a boat in my life I'm not Gona be able to get it on a stand unless there's a YouTube video out there I'm a fast learner lol

 

[Masarudizz]

No Title

When u click on the dark picture if u r on a phone zoom in

 

[Masarudizz]

It is not flush it is deep in there even though the pic makes it look closer than it is I'm worried I'm Gona drill into the block so Iam Gona try and center punch again I guess because I'm far from the center

 

[Masarudizz]

Should I jb weld that small hairline crack in the pic? Or it's nothin to worry about ?

Try your center puch again and use a left handed drill bit. Somtimes they will bring it out with the drill bit.

 

[Masarudizz]

No Title

The bolt might have broke bcuz there's no bracket

 

[Masarudizz]

Which way Do I spin the left handed drill bit to take it out?
