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 through
hull. 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 is dry.
Any advice would be much appreciated.
Thanks
Jake
