The dimensions of the o-rings - as I measured - are 63mm by 3.5mm. I could not find that size on a website that would ship to Canada
. I wanted my boat to be in service
soon again, so I spent the big bucks on the o-rings from Volovo $CDN 22 a piece plus taxes
I hope someone finds else a good source for cheaper rings. I would stock them for the next time.
At about $2800 for the exhaust
manifold, I did not want to reuse the old o-rings.
The heat exchanger was pretty clean. The exhaust elbow
revealed a small hole after taking it out, tapping the rust spot with a hammer, and probing with a screw driver.
has a low spot where the salt water
can collect and rust through. This elbow is 6 years old.I guess rinsing with fresh water
away, at least for layup
, would get a longer life for that elbow.
On another subject. About 3 years ago I installed a very simple fuel
polishing system in my boat, with the pick right at the bottom of the tank. When I first ran the system the the see-thru cup turned black for about 20 minutes. I run the polisher about once a monce for a few minutes, and do not see anything obvious ever in the fuel
Now I changed the polishing filter and found the cup bottom to be full of gunk as hard as epoxy
. I could not scrape it off.
