The Waste Cap that did not want to give up.

Speaking of using a pin punch and hammer, on our Waste cap, we were in Baja area of Sea of Cortez for 5 months and never used the cap due to the last pump out was at La Paz. So lots of salt water got on the bow and evaporated many times. We came back down to La Paz after about 7 months and tried to pump out. Cap was frozen and wouldn’t budge for two days. I used, heavy duty keys, liquid wrench, WD-40, heat gun, spanner wrench and then with a hammer (spanner wrench is a bit wrecked up now), hammer and heavy duty punch.

Finally I took the three screws off and removed the assembly from the boat. Boiled it in water, and soaked it over night in hot water, took it up to a marine tech. We tried my 26oz hammer and his heavier duty punch with a vice, he soaked it in muriatic acid for a bit, then we took a torch and heated around the outside while I got a cool wet towel in the center. You could smell the O-ring melting.

Then hammer and punch treatment again. Finally he gave up. I used his punch and my big hammer and marked a scratch in two places so I could see if I was making any progress. After 1/2 hour on the vise, it moved about 1/16 of an inch. Kept at it for another 1/2 hour and it moved a 1/4 inch. Another hour later it was coming around almost a full circle, still very hard, he then used a pipe wrench once the cap got high enough. You can see the nicks from the pipe wrench even after I filed them back down some. I cleaned it up and lubed with silicone grease. His diesel buddy had a new O-ring that fit. The cap is pretty well chewed up but it works good. So far I haven’t found another cap that will fit in Mexico. I’ve hear Vasoline will work great too and much cheaper. The holding tank inspection plate has been a bit of a problem in the past. I keep it lubed up too as with the other inspection plates and caps.

We’re headed south for a few weeks then back to Paradise Village in PV, MX, hopefully will be back up Feb. 15th for the Pacific Puddle Jump, PPJ, activities.

Glad to hear things are in the works for your pacific crossing. You will like it even more than Mexico.
