Main Message Board / Oil pressure sender
« on: October 04, 2017, 06:38:58 AM »
Hello,

A year ago, the oil pressure light and buzzer were not working. We called a mechanic and this is what he did: pulled engine control panel; traced wiring and inspected connections; tested oil pressure buzzer by grounding at panel – OK; rung wiring harness to be sure of continuity; grounded wire at oil pressure sender and tested -buzzer sounds. He determined that the oil pressure sender was bad and needed a replacement. Eventually he replaced it.

The problem is this: for the first 30 minutes after turning the engine on everything in fine. After 30 minutes (when the engine is already warm) the buzzer sounds if the revolutions are low (say 1500 rpm). If you open the throttle and increase the revolutions a bit (say to 1800 rpm) the buzzer stops.

Any idea why this is happening? Maybe the oil pressure sender needs to be tighten more? Or we need to increase the minimum revolutions?

Thanks for the help,

Juan

Main Message Board / Fuel tank leak or loose fuel sending unit?
« on: May 29, 2016, 06:00:07 PM »
Hi guys,

I wonder if you can help me with this one: I went to sleep on the boat on Friday night. Everything was fine. On Saturday evening I filling up the tank and after a couple of hours we went to sleep I smelt diesel, so I check the fuel tank I found that a small trace of diesel was running from the fuel tank down below the head sink to the bilge. So I took out the panel that covers the fuel tank (on the port side) and I found this at the bottom of the tank…(see picture). It was like touching grease but it smelled like diesel. Here is another picture (second picture).  It is obviously something that has been building up there. So my immediate reaction was, maybe I have a very tiny whole at the bottom of the fuel tank. But then, I realize that I didn’t smell diesel on the night before. It was only after we fill up the tank to the top. So then I touched the fuel sending unit and it has diesel around (see picture). So my second theory is that this unit has been loose and so when I filled the tank to the top, diesel has been spilling from them and gravity sends the diesel to the corner of the tank where you see the build up (first picture).

Obviously I cleaned everything, I tighten the screw at the top of the fuel sending unit (it was indeed loose), I ran the engine for a couple of hours to lower the fuel level and now I will wait until tomorrow to see if the diesel trace will reappear or not. In the meanwhile, I wanted to check if anybody has gone through a similar experience.

Thanks,

Juan

Main Message Board / Water heater
« on: September 27, 2015, 05:36:47 AM »
Hi everyone:

Last year I noticed that the water heater was leaking. As soon as I filled the water tanks with fresh water, the fresh water leaked through the bottom of the water heater. I supposed this was because the water heater got rusty at the bottom. Since I never use hot water and to avoid this leaking of fresh water I put a shut off valve on the incoming hose. There is no more leaking of fresh water. Recently I noticed, however, that the relief valve is warm (not necessarily hot but pretty much warm). Frankly, since a year ago, I never check this valve so I don't know if it has been warm all this time. The question is, is this normal? Is there any way to shut off the electricity to the water heater…I don't see an obvious on-off switch for this..

Thanks

Main Message Board / Bilge pump not working
« on: June 01, 2015, 08:43:21 AM »
Hi everyone:

my bilge pump is not working. It gets electricity...I can hear the buzz when I turn it on, but it is not taking any water out of the bilge. Any suggestions on how to start tackling this issue? Could it be the hose that is clogged? or the pump itself? any way to differentiate between the two?

Thanks

Main Message Board / Which water & exhaust hose?
« on: March 16, 2015, 12:48:25 PM »
Hi everyone:

I am in the process of changing the hose that goes from the water intake to the water pump (nothing wrong yet, but it looks very old to me). The hose has this mark "Shiledsflex 100-0580". So I figured that this is a hose with a 5/8" in diameter.

The question is whether I need more information. For example, in some websites there are water & exhaust hoses with the same diameter but with different psi: 725psi, 320psi, etc.

Do I need to worry about the psi as well? If so, which one?

Thanks

Main Message Board / Oil pressure alarm is gone
« on: June 23, 2014, 11:56:59 AM »
Hi everyone:

My oil pressure alarm stopped working. Before, you could hear the alarm when the key was in the ignition position and also in the glow-position (in that case, the alarm had a lower pitch sound), and would stop once the engine starts. Now, the alarm is always gone.

I thought the buzzers were too old. I changed them with new 12v buzzers from Radio Shack but still nothing...I checked the wires behind the panel, they were all fine...The motor seems to be running fine...Oil level is fine...

Any ideas on what to do (or check?)

Thanks,

Juan

Main Message Board / voltmeter reads
« on: June 14, 2014, 10:46:48 AM »
A quick question:

my voltmeter (at the cockpit panel) reads 12.5 when I turn the key to the ignition position. Once the motor starts, however, it goes to 15. Is this a normal read? I never paid attention to this before.

thanks,

Juan

Main Message Board / Wire size
« on: June 08, 2014, 12:08:18 PM »
Quick question:

what should be size of the wire connecting the alternator and the starter solenoid. Mine is #14. Shouldn't be #10? Should I change it? Does it matter?

Thanks,

Juan

Main Message Board / Starter solenoid fuse holder
« on: June 04, 2014, 05:43:06 AM »
Stu:

sometime ago you posted a picture of a nice starter solenoid fuse holder. I would like to change mine to something more durable, probably like yours. Is that a fuse holder you can find anywhere, or it is something special that you had to ordered?

Thanks.

Main Message Board / Fuel line leak
« on: May 29, 2014, 07:47:34 AM »
Hi, I need some advice on this.

Last weekend I was motoring when the revolutions slowly decreased and finally the engine stopped. I have discovered a small crack on one of the fuel lines right where it is attached to the fuel pump. I was planning to simply cut the line below the crack and attach it again, but I don’t know if I have to do something else. For example, is there a risk that air gets into the system? Is this then a job for a professional mechanic?

Thanks for your thoughts.

Main Message Board / Mast boot leak
« on: February 21, 2014, 06:40:01 AM »
Hi everybody:

I noticed that rain water is coming inside the boat through the mast. I can see the water marks along the mast when I stand inside the boat. Somebody told me something about the mast boot? do I have to replace this thing? or can I just fix it with something? How do I decide what is the appropriate thing to do?

Thanks for the advice.

Best,

Juan

Main Message Board / Bridge vertical clearance: 50 feet...too risky?
« on: August 18, 2013, 06:08:03 AM »
Guys,

the bridge at Choptank River in Maryland limits traffic to 50 feet vertical clearance. The head of the mast of the Catalina 34 (standard rigging) has a distance from the W/L of 49.7 feet. Has anybody gone below this bridge? or any bridge with a limit of 50 feet? Is it safe? too risky?

Thanks for your inputs

Main Message Board / Ice Box
« on: August 15, 2013, 03:52:57 PM »
Hi guys,

my ice box stopped working last weekend. I have no idea if the problem is the thermostat, the compressor, or what. I don't even know where the compressor is located...(not easy to find). Any guidance on how to address this issue before having to call a technician would be greatly appreciated.

Best,

Juan

Hi guys,

my boat has some yellow stains across various sections of the hull. Do you have any suggestions of a product to remove these stains?

I would like to polish and wax the hull, but it seems that I need something different first to remove these stains. Also what kind of polish and wax do you normally use?

Thanks,

Juan
