looking to replace exhaust hose...one section has wire reinforcement,

any thoughts? this stuff isn't under much pressure and i think wire
can create local hotspots, leading to the wire tearing loose from the
hose over time....

engine is 350 merc on a 27' tollycraft

Hose is rarely attached directly to a manifold - it would get too hot
and quickly burn up. *Most often it is attached to something called a
"riser" or "elbow" which is the point where raw cooling water is
injected into the exhaust flow. *

yep, the old stuff is connected to the risers..



All of the exhaust hose that I'm familiar with is wire reinforced. *It
prevents the hose from collapsing when it is bent into a radius. *I
guess it's possible that if you had a totally straight run you could
get by without the reinforcement but I'd talk with an expert before
doing that.

these are pretty straight runs, but there's no guarantee, i think
that, as the hose ages, it couldn't buckle under use...- Hide quoted text -

Well, consider the heater hoses n a car. Even in an enclosed system
like a car, there is usually a nylon webbing embedded inside the hose
and not steel mesh. Now on a radiator hose, especialy on the top hose
there is usualy a large "spring" fitting on the inside, to keep the
hose from collapsing and still make the hose pliable for shaping but
rigid enough to keep it from collapsing on cool down. then again we're
laking abotu nclosed systems on cars that run 190 degrees too.


Bob, if you're running a raw water system I think I'd just the simple
stuff with the nylon mesh inside. My hoses on my 350 GM are common
from NAPA. even the ones that carry the water to the manifold risers.
Now from the manifolds to the outdrive or exhaust ports in the hull,
that might be a different issue that I have no knowledge of.

this is actually an inboard (surprising for a 27' boat, but it has a V
drive). the marina guy said i could probably get what i need at the
autoparts store, but i don't think they're actually any cheaper.

these hoses go from the risers to the muffler, then to the exhaust
ports.

Sounds like the type that was on the last boat I had and had to replace.
Big honking hoses.
The engines were the MercCruiser (GM) 454ci and the hoses that ran from the
risers to the
mufflers were either 4" or 6" diameter. (can't remember). The boat yard
where I bought the
boat located and installed them. I never liked that boat. Sold it. Now
boatless. Miss the Navigator.

Considering your previous taste in boats, I never could figure out why
you bought that last boat. I would have kept the little GB if it were in
good shape, since it seemed well-found and also satisfied your need for
creature comforts when "bach'ing" it.

There were a few American Tugs or whatever that other brand is for sale
at a local boatyard. Looked lightly used. You ever look 'em over?

I may start looking around later in the spring. Right now I am too busy to
seriously think about another boat but I am beginning to get the itch again.
I've thought about them but for my boating interests a smaller, trailerable
type boat just won't hack it.

The reason I bought that Mainship Sedan Bridge was because both of the other
boats we owned sold within a couple of weeks of each other, meaning the
Navigator and the 36 GB. My intention was to keep one of them (whichever
didn't sell first) but we received offers that overlapped. Not being 100%
sure that either sale would be consummated (contracts favor the buyer), I
felt it prudent to accept the offers on both boats. As luck would have it,
both passed their respective surveys fine and I was suddenly without a boat
for the first time in about 14 years. The Mainship was in decent shape,
was not huge bucks, so I bought it just to have a boat for that season. But
you are right. It just never grew on me.

I liked the GB a lot. It was a different style of boating and very
relaxing. But, the Navigator was by far my favorite boat. Not the
prettiest boat in the world but built like a small ship, very sea worthy and
very comfortable.

I recently was informed of a 2001, 48' Ocean Yacht Sportsfish that can be
had for short bucks. *Really* short bucks. Owner is a friend of a friend,
in his 70's and just wants to get rid of it. Thought about it, but again,
just ain't my style.

Meanwhile, we still own two slips up here, one for up to a 55 footer and the
other for up to a 36 footer.
We'll probably hold onto them for a while as they generate income due to
seasonal rentals. Slips are hard to come by in MA and if one is in the
market for a slip type boat, the first issue to resolve is to find the slip.

Navigator, big plastic boat. Never liked the lines or the look and
they drop value pretty quick. Somebody was happy with you having paid
the depreciation.

If I were without concern for budget and staying close to shore, I'd
be looking at a Fleming Pilothouse 55 or the Ocean Alexander Mark II,
a pretty boat in that same range but they're hard to come by.

If I could convince the Crown Corp I worked for to double my modest pension,
that's the type of boat I'd take command of.
Up here, we need something seaworthy & comfortable for coastal cruising...
especially with a somewhat short, usually damp, boating season.

I liked the looks of that Navigator...looked "shippy" to me.

i didn't want to pull the hoses off the risers when i visited the boat
on saturday...so i measured the circumference.

calculated 3.88" diameter. from this i assume the ID was 3.5" with
about a 0.2" thick wall.
