Question for CD-33 owners...

Post by Zeida »

I just had the Tides Marine Sailtrack installed on Bandolera's mast, which is supposed to make hoisting and dropping our big mainsail easier. I had to remove the mainsail in order to have the rigger install the full length battens, small batt cars and SS slides that go with the system. With the system installed, we were ready to get the main back on the boom, only to find out that the outhaul, which runs inside our boom, was totally stuck and would not move. We could not get the sail reattached to the boom. A day later, the rigger and I tried to pry open the end cap of the boom, which is held in place by 3 bolts. They were frozen, probably never moved in the boat's life. We removed the boom bails and the outhaul moved some, but not enough. We unscrewed the exit plate on the boom through which the outhaul line comes out, and together with the line came a 3 ft. long metal rod, and two very large Spartan fiddle blocks, through which the outhaul line joined the wire that protruded from the end of the boom and attached to the clew of the sail. After 3 hours of hard work, my rigger was able to rethread a new, simpler outhaul system with two smaller, newer Harken blocks and a 3 x 1 purchase. Has anyone experienced anything similar? I decided to replace the wire, and now my entire outhaul is of a very strong new line, which will not kink. I was very surprised to see the strange set up of the outhaul, but after our modifications, it is much simpler and easier now.

I never explored our outhaul but it has worked great from the beginning. I always suspected a couple of blocks because of the leverage I get from the line that comes out of the boom. I think I got the end of our boom off when I made some changes to our reefing cheek blocks but I didn't take the time to explore the dark tunnel to see the outhaul mechanism.

Now that I think about it, I have never heard the blocks rattling around in the boom when the outhaul is relaxed. Maybe I should look sometime.

Zeida,

I never had the boom apart either but I imagined a block system in there. All I have added was a second reef set up.

Good luck,
Paul

Paul and Al... thanks for your comments. BTW, I am considering replacing my current 2" outside diameter heat exchanger by a slightly bigger one, a 3" outside diameter. I remember reading somewhere that the engine manual of the universal 5424 actually recommended this change. Has anyone done this? It seems to me the engine will benefit because of the slightly more cooling water running through it.

Before we changed out our 5424 we seemed to have consistent temperature results. It seemed puzzling at first but we often ran at less than 160 degrees. When we pushed hard we consistently ran at 190. I concluded that we were not warming the engine enough when we took it easy but that we were finally reaching the thermostat setting when we ran it harder. The heat exchanger wasn't needed at low speed and it seemed very adequate at top speed.

We did have our heat exchanger off one time and I was able to shake out the debris. We had accumulated a lot of zinc bits from the anodes that had corroded and fallen off. That must have helped the flow but I never sensed that the flow was lacking.

Al, what engine did you replace your old Universal with, and did you have to do extensive modifications in the engine compartment to fit the new one? My Goldie still runs ok, but warms up between 185 - 190 at all times when going at about 20 rpm's... past that, she tends to get hot... and I have to slow back down again. Do you have any photos of the new engine setup? Would be nice to see it.

We replaced the 5424 with a Yanmar 3YM30. We removed the pipe mount and glassed in wooden stringers. I also removed the partition between the engine compartment and the wet locker. I don't have a web site to post photos but I can email some.

Al, I would LOVE to see any of those photos of your current engine. One of these days, I will also do away with the wet locker. My email address: zeida.cecilia@gmail.com
Thanks

Al,

I would love to see those photos too. I may be doing that job at some point.

But I currently have no overheating issues with our 5424 in fact it is very rare I get up to full temp on my gauge. That bugged me the first summer, I replaced the thermostat (the source of a story in Good Old Boat as I stripped the bolt off!) But still the same results so I live with it. I thought it may be the cold Superior water, I don't know.

I am hoping to have the exhaust picked up from the welder this week and I'll put it on next week right before launching. Hope it all works out.

All the best,
Paul

Paul,

I don't know if they show what's expected but I can send you the same photos if you send me your email address. You can either post it here or by PM.

Al, the photos of the conversion from your universal to the new yanmar are great. Thanks a million. Makes the future job so much easier when we can TELL and SHOW exactly what we want done, rather than be hostage to whatever some "expert" tells you what to do!

Paul D. -where exactly is the thermostat in our engines? I need to find out if mine is working properly. I am about to replace my current heat exchanger with a slightly bigger one. I would hate to find out later that the problem was the thermostat. thanks.

Zeida,

Paul may not have had a chance to check but if I recall correctly the thermostat housing is near the top of the engine at the forward end, slightly to port. One hose coming out leads to the front of the exhaust manifold. I have a parts list that shows the individual systems and I can snail mail that if you send me an address. You can use the PM on the board or the return address from the photos.

I don't recall exactly but I believe the water heater hoses also attached at the thermostat housing.

Zeida,

Al is correct. It is in the housing right at the forward top middle of the motor with hoses off of it. Now be careful pulling it out as I stripped the bolt head off and good. Soak for a long time with repeated sprays of PB Blast or WD-40 and back out. If your motor was rebuilt it should be fine. Mine has not been overhauled and the boat was stored for many years by the first owner. So I think I may have had a special case.

Whenever I oepn something up on that motor I take a deep breath first and soak the heck out of it! The weird thing about my thermostat is that the gauge reads low so I never get up to temp. I have tried closing the seacock halfway, reving higher and as I said, changing the thermostat. The motor runs well so I decided to live with it. But it still haunts me like a Lake Superior fog.

I have some excellent pictures and will try to find them and get them in here. Give me a day or so to find them and post, I am only home for a short while and hope to go up to the boat and launch this weekend.

All the best,
Paul

Zeida,

OK let's try this. It is not the picture I was looking for but it does show the thermostat housing front and center under the brown plastic oil vent tube. The larger painted gold hose comes off to the right from it and a smaller one comes off to the left. There are two bolts you get at with a socket from the top.

You will need to drain the coolant somewhat down to the level of the housing. I did that by preparing a plastic gallon jug and taking off the hose on the right.

My project this year is replacing the white-taped exhaust riser in the back. I just got a new one built at an auto place for 200 bucks, got new heat tape and permetex high temp gasket silicone from Napa to reattach this weekend for launch. The old one fell apart the last run of the season while I was winterizing. It was quite convenient. Sometimes, fools have all the luck. As you can see from the picture, I am most certainly a boat fool. But I take solace in the fact that at least my brother is too, and he has a bigger, more complicated CD.

Paul, thanks a million for taking the time to send me that one picture... worth a thousand words! Now I finally know where the thermostat is! I will be checking it out this coming week to be sure things are right in there. Thanks also for your tips! Will let you know how things go. I also plan to replace the small 2" heat exchanger with one the next size up, and hope Goldie may like it better. Hope you can get your boat out on the water ok and go sailing!
