Re-mounting motors, need torque value?

[Ridge Runner]

2004 GW 282 Sailfish; going to start putting things back together, finally!
Is there a torque specification for the bolts mounting the bracket to the transom, or do you crank on them until you can't get any more?
My bottom bolts are 'stuck' in the transom. They are not coming out without some serious hammering. Would you knock them out in order to get sealant into the holes, or leave the integrity intact?
5200 or 4200?
TIA!

Hi Ridge Runner,
I would knock the bolts out, drill the holes ever so slightly to accommodate for added dimension of 2-part epoxy in the holes using a small diameter wood dowel.
Once the epoxy cures, good to go. I also would add bead of 4200 on the underside of the bolt head, and where the nuts will tighten down on the transom to make sure it stays watertight.
Your hull looks SO clean, congrats!

PS-I wouldn't over torque the bolts, you could create problems in the gelcoat from the stress. I tightened mine slowly, switching from one to the other, and had plenty of 4200 on the threads so they won't spin off down the road.

I am repowering my boat now. The torque specs that I have seen are 40-55 ft. lbs. I am using Boat Life Life Seal. It is rated to be used below the water line.

So the old sealant is doing its job ! You can warm them up with a torch and tap them out. Then I clean out the holes with a 1/2 inch drill. I prefer 5200 or Below the waterline Boatlife to re seal. Roll the bolts in the sealant and be sure you have good coverage on the inside of the holes. Also I like the transom support plates for more stability and load bearing across the top bolts.

Collinite!

Update: I decided to run the bolts out with the impact, epoxy & re-drill all the holes, seal with 4200, and torque to 50 foot pounds.
I also bought upper support braces that came last night.
Now all I need is for this rain to stop!
I did get the bang cap done though...

Use a torch and you may set the coring and fiberglass on fire. I would leave the bolts where they are and make sure you add a sealant around them on the outside.
The bolts were probably bedded with 5200 and that is why they are stuck. I wouldn't hammer the heck out of them for fear of delaminating the structure
