While winterizing a newly purchased 1983 catalina 30
with a universal 5411 raw water
cooled some serious confusion came about.
Only owned and used the boat for about 2 months before haul out
. One of the first thing noticed was the lack of water
spitting out of the exhaust
. I would estimate the amount of water
at less that half the amount expelled by other diesel
in board powered sail boats that I've been on. After some research
I was convinced this was an impeller issue, which upon disassembly, no doubt needed changed, but did not change the amount of water exiting the exhaust
. I should note that this engine
has NEVER had a temperature issue, even before the impeller was changed. If anything, I was shocked by how long it would take for the temperature gauge to register any thing at all.
Which brings me to my question/concern. With the boat being on the cradle
and running the engine
to circulate antifreeze
throughout the system, I wasn't surprised at the lack of antifreeze
spitting out the exhaust port. More so I was shocked at the amount of antifreeze pouring out of the area where the prop shaft exits the hull
. I would estimate that 90% of the fluid being circulated through the engine was exiting the boat in this area.
So now I'm fairly confident that antifreeze has been properly ran through the engine. But very confused about where the antifreeze is exiting. I need to understand this. No one at my marina seems to be able to offer good advice. Those nice enough to offer advice seem to know less than I do, which is not much.
Just to recap, this engine never even came close to getting " hot" and the bilge
Any advice would be much appreciated.
