I’m juggling many different things on the Roamer refit right now, but all of them are essential must-do items if I’m going to splash later this year. Getting the Cummins 6CTA Diamonds attached to the exhaust system, fuel lines, and raw water are three of those things. Some exhaust parts arrived a while back, so it’s time to reinforce the fiberglass tubes where the clamps squeeze the hose. Without reinforcement, the clamps can cause the fiberglass to crack.
In the pic above, the muffler is sitting on a tray I made using scrap aluminum sheet from the aft deck enclosure and 6063 aluminum angle. Because I’m using Centek waterlift mufflers, I wanted to position the muffler as low as possible so the spill-over point from the muffler to the exhaust outlet is lower than the spill-over point of the dry portion of the exhaust riser. That will make the exhaust system inherently safe by making it virtually impossible for sea water to back up into the dry part of the exhaust. I’ll be welding that muffler tray in soon.
While the epoxy cures for the crush sleeves in the exhaust elbows and outlets, I’m wrapping up fitting the muffler trays. But there’s other stuff going on, too.
