Newbie asking for help re: $$$ install of Exhaust

[brettportzer]

Not sure if this is helpful but I special ordered 2-1/4” Trident 202V silicone hose and got it dropshipped from Trident themselves, and it was folded from 36” down to a foot and rubber banded together.

Popped right open with no marks, so, it is pretty malleable.

Can you move the muffler? Maybe slide it forward and work from the transom forward. Get the aft hose on first, then the one in front of the muffler.

All good ideas. I will try folding the hose inward and see. The muffler is 60" long, weighs 167 pounds, 18.5" diameter. With inlet & outlet that are 6" long and 8" OD. The installer built 2 V-shaped supports (that are fixed to the floor & sides), that go under the inlet & outlet. So once the muffler is dropped in (which is far from easy), the shoulders are locked in. The only way I can use the exhaust hose is by slipping the hose on the fiberglass pipes leading to & from the muffler, then pulling the hose over the inlet/outlet. The installation was poorly done. The supports are not well spaced out, are not at the right height (off by 1/2"), some wiggle, etc.

Out of the 4 connections for the mufflers, the port stern is the most difficult. Due to the fact that there is not enough room to slide a good length of hose back.

The muffler is a beast and a PITA to handle.

Maybe pull the mufflers back out and straight pipe it until you get the new ones. At least you can use the boat, albeit at a higher decibel level.

This is actually somewhat easy on silicone hoses, you're going to laugh at me, but get water-based sexual lubricant (astroglide, wet, or something similar - make absolutely sure it's water based, counterintuitively silicone lubes will dissolve silicone rubber) and a heat gun. Lube it up and hit the silicone with the heat gun for 30 seconds, it'll go right on.

I am having fiberglass mufflers built by Verbatone.

That was a good move, that's the company that originally made the mufflers for hundreds of these boats in the first place, they probably still have the same molds so you'll be sure it'll fit in the supports and cutouts that are already inside the bottom of the master cabinets. Exactly what I would have done.
