Oh this ain't good.......
 

First Thursday he said "No problem it'll be done in a day".......end of the first day he calls and says "the motor mount bolt won't budge!"He gonna let is soak and try it tommorrow.

Second...No word from him Friday..then Saturday morning which is yesterday I come home to get my old wheels..and there the boat sits....so I load up the wheels and leave I have **** that I have to get done first.

I call and he says "I couldn't get the two bolts out and are you gonna be home Sunday morning around 10:30 a.m.?""I'll explain what's going on.".........WTF is that supposed to mean?
Sure I am....not gonna be on the boat so why wouldn't I be?

Of course I wasn't a smart ass but you get my point.The I notice the outdrive is not here!......:mad:

These bolt look brand new....the two that go to the stringer that is.
The motor mount is in great shape but where the two halves come together the shaft the big nut sits on is pretty bad looking.........doesn't look like anything is gonna come off there...but then again you have two other options.....two bolts on the engine for the top part of the mount and two bolts on the stringer for the bottom part of the mount....WTF?????

Alrighty........I went back out to the boat and found what he's having a problem with....

It's not the motor mount bolts......It the bellhousing to transom bolts......right there in plain view from the top.....the heads of the bolts are in good shape....and the room for access is pretty good too.......what gives here?......:rolleyes:

I swear......if I get these bolts out@#!#%$@$#:crazy:

Put a 3/4in 6 point socket on a long extension on a breaker bar and give it a try yourself. They usually come out easy.

Salt water boat? Maybe not so easy.

Terry, the rear mount bolts (the ones on the inner transom plate/bell housing) are aluminum. They are about 4.5" long or so and go down to an aluminum nut that is self locking.....you don't need to put a wrench on it....if you break one of them, chances are you will not be able to get the nut out of it's location either. Try really hard NOT to break one of these bolts.

'Foul

Ouch! Don't break that bolt

Okay here's the skinny.......The guy came by and showed me the problem.....the bolts appear to be steel!!!

The y ain't movin.....he said this is not his boat so he wasn't gonna grind that head off.....he took it to another shop with a bigger impact......3/4 w/250psi.....Nothing....wouldn't move!

He said if I grind it off he will be able to pull the motor and should be able to get the bolt out?????

Can you get a torch to them to heat them up?

That's the other idea.......:crazy:

Well, someone used the WRONG bolts then. When you do get them out, replace them with the correct bolts. Get them at most any Merc dealer.

I don't recall ever running across a bolt I couldn't get out, IF I could get heat to it BEFORE I rounded off the head.:)

Ya know what....I just felt the bottom side of this friggin bolt...it doesn't sit in a hallway so to speak it sits open to the bottom......with a slot to hold the nut.......screw this....time to grind.....:hothead: :hothead:

Am I right about this?????........this nut just sits on the bottom side of the transom assembly in a slot?????

Nothing else holds this bolt to the assembly?

If someone replaced it with a stainless bolt and a stainless ''nyloc'' nut" and neglicted to use anti sieze, it may as well be welded together.

Yes the nut slides in from the front. Mine came with Stainless Bolts and aluminum nuts. Use never seize always on these to allow removal. My aluminum nuts have been replaced with Stainless nylocks. Stainless on aluminum will corrode worse than stainless on stainless because of dissimilar metals. Stainless on Stainless needs lube or they can gall threads pretty easy. Cut the heads off then you may be able to drill them out once you get the motor out. Just my .02. Good luck.

All of the rear mount bolts I have seen have been steel and have fine threads. The Nyloc nut on the bottom sits in a slot, it holds the nut and keeps it from turning.

As far as heating it, the surounding material is Aluminum and the area is real tight!

Have you sprayed the nut and bolt with WD-40 or PB Blaster and let it soak?

The only ones I ever had trouble with were salt water boats and the bolt was frozen in the tube it goes thru, on the bellhousing. It wasnt the Nyloc nut keeping the bolt from turning.

If the bolt is froze in the tube (it goes thru,bellhousing) then even if you snap off the head you still will not be able to lift the engine out!

Foul, the bolt is steel and as you say the nut is aluminum. The problem is usually not that the nut is locked up, but that the bolt is seized in the engine mounts.

Impact does not work because the mount is a steel sleeve bonded to rubber, the rubber absorbs the impact. Just taking the head off the bolt will not help if this is the case. The breaker bar and 6 point socket is a good start.

Been a while since I did one but I seem to remember cutting the bolts with a swazall, cut right against the flywheel housing then there should be enough left of the bolt to get the remainder out of the alum nut after the engine is out. Of course the rubber mounts get replaced.

Marc is right!

Thats what I meant when I said froze up in the tube the bolt goes thru.


I have got really pissed and just turned them with a breaker bar untill the rubber around the tube spun in the bellhouseing like spinning the hub on a prop.

If wasn't easy but I got the engine out.

Well, I knew something was aluminum!! LOL!! I always use anti-sieze when I put mine back in (I tend to have my motor out more often than most......run em hard, break em hard!!). Never had trouble getting those bolts out though. Then again, I don't reff them down real hard when I put them back in either. Aluminum nut, don't want to strip it out. That's not to say I don't get it tight, just don't put that extra 1/8th turn on it like you would a steel/steel combination. Good and snug & that's it.

Does anybody know of this bolt is a standard straight thrugh bolt or is it something special.....I.E. wide as hell.....or is that just the sleeve of the mount?....

Thats the sleeve of the mount. The bolt is 1/2 shank I think.It is tapered at the tip to help guide it when installing it.

Heat it up with a torch and wick some parafin (wax/crayon) or WD on it. Be carefull with the surrounding rubber.

Shore,

It`s just a plain bolt I think about 1/2"thread. As mentioned before, in salt water use, the bolt siezes up in the steel sleeve on the bellhousing motor mount. I`ve been there before and the last time I fought with it pretty hard. One came out with a 1"drive impact gun and the other one stripped the hex. I did the breaker bar thing too, 1" drive with a 4 foot pipe and it still would not budge. Ended up cutting the head of the bolt off with a cut-off saw and pulled the motor with an electric chainfall. The sleeve pulled out of the rubber mount in the bellhousing. This was kind of a drastic measure but we did not care about the boat, It had been crushed by a big tree and I was stripping the boat and did not have to be careful.:eek:

Good luck,

Kurt

If you have access to a bellhousing thats off an engine you will see what your up against.

Good Luck, They can be a *****! Now you understand what we techs go through for the love of working on boats LOL.

If you get upset,take a break and have a cold one. Don't break any fingers.

Keep us posted

Drillin her out boys..........stay tuned......titanium to the rescue....:rolleyes:

The joys of ownership!

Minor technical issue........drilling now......3/16 right through.....1/2....Umm no!

An if you end up needing a bellhousing, guess what I have, 2 of them that will fit your coupler and not a bravo coupler. Your welcome to one. Good mounts too.

Formula31....You're kidding right...?....Ya know if I ever have a kid ....Tom is gonna be his or her name...

Needless to say the drilling didn't work.....3/16 went right through.....nothing else did....so there she sits!

I've been keeping a real cool head about this and that is par for my course.....

Oh and did I mention that the little FIRES that those of you may have seen when leaving Daytona this afternoon....It was the entire wooded block across the street from my friggin house.....HOLY CHIT!!!!!:crazy: :crazy: I spent two hours hosing the roof yard and everything else in the yard down...little fires everywhere.....Good grief.....:confused: but all is well and wet!

;)

Tom if you would be so kind as to send those parts too I would soo apprecite it and those mounts would be greatly appreciated as the ones that are on there now are buggered beyond imagine...:rolleyes: of course this would be my fault also!

OK, one flywheel housing on its way. You will need to get 2 new mounting bolts and nuts from merc. Maybe springs and washers to if they are shot.

That's great F31, nothing like the OSO brotherhood!:)

Man I tell ya what......Formula31 rocks...ya know what they say Tom!

What goes around comes around......you're gonna have plenty coming back to ya!


Ya know guys I don;t know how many of you have been following my repair issues but this is NOT the first time Formula31 had helped me out on this issue.And that I will remember for a LONGGGGG time.ThnX Buddy........Terry


I wish I had a webcam to let you guys watch me do this DAMN boat!.....You'd be amazed at the patience from a person with tiny mosqiutos biting him $30 Titanium bits breaking off and black ashes falling on his head from the fire across the street.All the while talking politely to the 70 year old neighbor right behind him....
:crazy:
