My earlier post was written before I saw APS's post. He makes very good points as does Dave R. The fuse is a protective device so you should know what caused it to vaporize or find out why before replacing the fuse and/or holder. I was just answering your original question about removing a stuck fuse cap.
Heat shrink tubing may be shrunk (correct word?) with a hair dryer. Most people do not have the heat gun often used by techies on that stuff. However, the heat shrink tubing may not be waterproof. Water may be able to migrate up the tube. You might want to use a true wire weather sealing product (Radio Shack Coax Seal may be right). You must think about the vibration, wire stress, electric current, temperatures and other conditions that this fuse will likely endure in your boat. You may want to consider having a pro do the work with their marine grade parts, tools and experience. Crimp on connectors can be very good but the crimp tool is important. A poor crimp can be a source of heat and eventually maybe sparks. Err on the side of safety.
Good luck Bigdog. Let us know what caused the original fuse to explode or disintergrate. High current spike, small gap between contact and fuse or ...?

Mark, you seem to be preoccupied with issues of
speed.
Let me briefly respond to your statement. In-line fuse holders are sold with specifications including a maximum current handling rating. Often referenced to 30 Volts DC. The replacement in-line fuse comes with a WIRE (see pictures above). That wire MUST be of the appropriate size/rating to handle the maximum current intended and then some. They are sold together as one unit so I stand by my statement. You need to buy an in-line fuse holder that will handle the current. If you want to talk high voltage then the electrical characteristics of the material of the fuse holder can be important.
Hope this helps clarify the issue. If you question it others might have too
Happy, safe and moderate speed boating to all
