Here I am again.....now it has been 31 years(!) running raw water with no thermostat.....
.........but here I am again needing a whole new exhaust standpipe!
The last time it corroded and failed was 2012.....THIS time the elbow
area just below the steel standpipe is swiss cheese black crappola.
Now I see this Tartan ten SS Moyer standpipe....and it arrives today. It will
take some fiddling but I think it will fit my Columbia 29 Mark I 1965.
I finally gave in and bought the Indigo bronze raw water thermostat 140 degree
"kit" and will FINALLY run this beast a little warm......
(All below is from my original post of 2017...)
Crazy I know...but my A4 early model, mounted in my Columbia 29 1965,
has always been running with NO thermostat and NO manual valves since 1989 when I bought the boat. I have cruised this boat from Seattle up to Desolation Sound.. and all over the place with little cooling " issues".
I can reach through a 4 inch hole in the cockpit and touch the vertical
standpipe water muffler i built...and warm my fingers but never burn them.
My temp gauge, nice one..never gets off the needle. The engine runs great.
But now, seeing my plugs after a five hour motor trip being pretty black.. I may finally give in and and am ready to run it at 140 or so.
So.....after reading waaaay too much on the subject I see three alternatives:
1) Go cheap..go simple....install a stainless 90 degree ball valve in the
cockpit to divert water and control the temp to whatever i want.
Install some manual "stops " so I can repeatedly position it for the temp
I want.
2) Go "old school" original. Buy the original design thermostat housing sold
by moyer which mounts on the top of the manifold..then buy an 85 dollar
Dole and a bunch of misc. fittings.
3) Pay Indigo $150 for their SS thermostat housing and mount it on a
bulkhead. Then I guess I still need a pricey thermostat..
I am a nut for absolute simplicity on a boat and am also a cheapskate.
So..number one looks intriguing but maybe it is a bit silly. Comments appreciated. Cheers!
