I have six 1/2" stainless steel bolts siezed in a threaded aluminum hole. They are on a jack plate rated for a 300 HP outboard motor.
I need to lower the jack plate about an inch due to some additions to the bow of the boat. The SS bolts are siezed up in the aluminum from oxidations and a lot of salt water. I've put every thing I can think of to free or loosed the oxidation but can't. The aluminum is pretty hard and I can't apply any heat for fear of making it brittle.
Anyone have any suggestions?
thanks in advance,
