Trey,

Try using MAP gas instead of propane, burns hotter and heats the metal a lot quicker.

Jumping my problems over to my thread instead of the other one!

The two screws on the left are originals, the one on the right is a replacement I believe. There are 8 replacements in all on the side bypass cover. All of the originals came out fine with an impact driver (the kind you hit with a hammer) but two of the replacements have popped their heads. I haven't tried working on the other 6 replacements recently. Been too busy, and all I have is a little butane torch.

Gasket question for the motor experts...

For the Head gasket, does it need to be sealed with "Perfect Seal #4" type sealant since it's in the 'hot' section of the power head?

Aircraft paint stripper-be careful..

Nevermind... I found my digital copy of the service manual.

from what i recall about head gasgets, torque dry.........(cold)
after running motor for the first time, reaching temperature, allow to go cold and re-torque

this is from memery of my automotive days 40 yrs ago.........
let me know if anything differs from this........

Found these... But do I need to put anything on the gasket, or just as it is?

I have a parts catalog, but I don't have a service manual for the 1957 Evinrudes... does anyone have the torque specs/pattern for the head bolts?

Also, does it go on dry, or do I need to put any other gasket compound on it?

Dan Gano care package has arrived!

I love TP Tools.
