Broke powerhead bolt

[35hpdennis]

I replaced powerhead gasket and when torguing down bolts I broke one. Will be OK to run engine like that. I assume it will blow gasket at that position.

What motor ?-----What bolt position ?-----Pictures would help.

i would lift the power head and do the job properly by removing the broken bolt and replacing with a new or used one regardless if what motor .

1983 evinrude 35hp. It the one point to or the one above marked 2. It raining right now so I can't verify at the moment.

A cylinder head bolt.-----Not good to have a missing one.

It looks like you are pointing at a Cylinder Head Bolt. If that is the case, then you must replace it. If you are pointing at some other bolt, provide a better Pic, even if you have to wait till the rain quits

 

[tphoyt]

If you broke it putting back in it won’t be that hard to get back out. Just start over and do it right.

 

[jimmbo]

Get another Head Gasket, they are a tighten down once design

I would also like to know how to pull the powerhead out. It will need to be in order to drill out the bolt if necessary. I see two bots inside the cowling holding the powerhead, are there bolts below also? Does the lower unit need to be removed? I have a manual but don't see anything about this

What did you tork the bolts to?

If it broke next to the head than when you pull the head off you should have a stub you can grab and spin it out.

I Believe if memory serves me right... power head removal requires lower unit removed so you can access bolts from withint...and possibly shifter...
I have one I'll look at when I get back to the house.
I know you can look at the various diagrams from the likes of boatsDOTnet and see what and where.

I would suggest before removing power head see if with head removed you can get ahold of it or tease it out. Just a thought of course.

Also...I would replace all head bolts at that point....on the assumption of them possibly being fatigued by a prior wrench.
And a new head gasket.

I'm hoping that's the case.

Powerhead can be removed without removing the lower unit.---Shift rod coupling does not need to be touched on side of exhaust housing.------But take the cylinder head off first!----See what needs to be done.----If you have not resurfaced the head it will be warped.----All 1983 cylinder heads are warped after years of service!

I'm hoping that's the case.

I torqued them to 10 ft lbs, then 15...and was trying to go to 20. None got to 20 and after I broke one I stopped. I wish I had bought new bolts, but the were like $9 each on boats dot net. I should have gone to a bolts supplier.

 

[racerone]

Were threads cleaned with a 5/16-NC tap ?----What torque value was used ?----Were you using the proper bolts ?----Correct , no need to buy factory bolts at all.

Well, you did it correctly.
