How hot can this get and would this work in a engine block sleeve (this were the piston goes up and down ). Its for a 2 stoke 80cc dirt bike ?

If the glue is to be placed on the inside of the sleeve to cover a defect where the rings pass over the repair, this is an extremely demanding use and liable to fail. I'd use a dremel to grind an undercut "dovetail" in the defect and apply J-B Weld High Heat epoxy putty. About 500 degrees max.

My deck screws are no longer biting to secure deck on boat. What product do u recommend to fill hole and redrill?

I just finished filling holes in boat deck that no longer would hold the screws. It dries white. I filled the hole and after curing time I redrilled the holes and mounted the lids. Held up fine so far

Can I use this product on acrylic plastic?

No, you need to use the JB Weld plastic bonder, item 50133 or 50139. Thanks, JB Weld Support

Is this product uv resistant?

"I'm confused, the product description says it is UV resistant." Let's rewrite that (pretending that we have a sixth-grade education): "I'm confused; the product description says it is UV resistant." Unfortunately, the J-B company is using the name MarineWeld for two very different adhesives. The white kind (in syringes) and the gray (in squeezable tubes) differ in much more than color.
