A while back, I posted a threat about whether to keep my little diesel engine
with a gas 350 on my 31' Trojan. After a lot of research
, I've decided to keep the diesel
. So, here's what's next:
DRY STACK CONVERSION!
The Isuzu C240 Diesel engine
I have is currently set up for a keel cooler
(engine, trans) and raw water cooling
in the manifold only. In fact, the water
enters the manifold right at the outbound end of it and essentially just cools the tip of the manifold before water
gases mix and go overboard
Since I have to install a keel cooler
anyway, it would be easy to add a little extra capacity to keep the engine cool without raw water exhaust
. Then, thru-hulls for water would be closed up. The current
manifold is wrapped to keep heat to a minimum and I may be able to use it. Exhaust would be routed up through the floor in a 3 or 4" pipe with a truck muffler
. That would be enclosed in 8" stove piping and boxed in. The stove piping would be vended so there should be plenty of engine room ventilation.
The entire setup for this dry exhaust never enters the cabin
due to my boat's design - noise
and heat should be at a minimum.
Exhaust gases are routed 7' up from the deck
courtesy of the piping.
This setup in the end should be easier to maintain and last longer.
Less thru-hulls at the end of the conversion - always a good thing
Still able to keep my keel
cooler and cabin
heater + hot water setup.
It's different and therefore cool.
If I ever needed to repower
, I could use a truck engine with minimal marinization.
So what do you think? Anything you would add?
