I am going to guess that a late model Maramu is the same as a SM.

The mast side end of the bungee is secured to a fitting (like a hook) under the boom, near the mast. Look under, and you should see it.

The boom end side of the bungee is tied to the rope part of the boom lift. Untie the knot and pull the line free of the block on the end of the wire topping lift.

The rest of the job is fairly straight forward. Use a piece of line on the mast end so you don't loose the bitter end. You will probably have to do this job twice because you won't get it tight enough the first time. When complete, you shoul be able to lift the boom 60CM and the bungee keep the lift line tight. Consider this when doing the job...you will still probably do it twice. Use two 10mm bungees for the main.

Everyone, these bungees have a life of about 6 years. It is always better to replace before failure and 10mm bungee is very cheap.
