O`Day 31 Charleston
Just wanted to say hello. Acquired my first sailboat, a 1985 O'Day 31, back in August, moved aboard in September, and she's been schooling me in her preferences ever since. She's a beauty who hasn't been used much in years.

So far, I've learned a good bit about her by researching, rolling up my sleeves and digging in, and by asking the advice of the knowledgeable owners here at the marina. I now have a pretty fair understanding of: the cooling system (overheating, turned out to be a cruddy heat exchanger), fuel system (sludgy tank/filters, now clean/replaced) - that lesson involved being towed back to the marina after heeling in some glorious wind) and the electrical system (replaced the charger, many excursions into the DC panel, lots of following wires to their often-corroded ends).

Today, I'm tackling the recently failed temp gauge. Purchased a new gauge and it doesn't work, will be checking the sending unit today. One of the old salts here at the marina said I need to make sure there is compatibility between the new gauge and the sensor - the old gauge was an auto parts store Sunpro. Trying to upgrade when I replace. Any ideas on this would be appreciated.

She still needs lots of hose replacements, wiring connection replacements and she has a few cabin leaks, one that will entail replacing the shelving over the galley. The hot water tank was stored in a locker - need to troubleshoot it and reinstall. Will be pulling out the old pressurized alcohol stove soon - tank leaks and the oven knob shaft is broken. Planning to build cabinets and set in a twp burner propane stove. Storage for spare parts, tools, etc. is pretty limited on this boat.

That's my story and I'm sticking to it. Advice and palaver is welcome.

Sounds like you have the right attitude for boat ownership,fix the problems as they show up and keep a good attitude.
cheers

Re: Ahoy!

Thanks, Seneca. She can push me to the limit of my patience at times, but we're a good team.

Re: Ahoy!

Welcome. Pictures are always appreciated.
I think you will find lots of good (and occasionally bad) advice here. You filter it and it's priceless.

As for troubleshooting the temp gauge: Do you have a multi-meter. These days they are cheap.

With a meter set on resistance, and the engine off, check to see if there is anything connected to the other end of the wires.

Re: Ahoy!

Ken, not many days go by without me testing something with the multimeter - will be putting it on this setup shortly.

Wasn't sure from your mention of pics if you saw the album - I have a few up of the boat inside and out.

Re: Ahoy!

I would strongly suggest using a new sending unit that matches the new gauge. It is very difficult to match and calibrate a new gauge with an old sensor, or vice versa. I tried to explain this to my captain on a commercial boat I served on, but he insisted we mix new gauges with the old sensors, or new sensors with the old gauges. We had four sets of gauges for four engines. In the end, some of the gauges were 20 degrees out of calibration, and some worked in reverse.

Re: Ahoy!

Good advice, Tom. Pretty sure the sending unit is the culprit - multi meter showed low resistance when cold, should have been higher, then removed and grounded the wire coming off of it (still attached at the gauge) and the gauge needle jumps.

OK now I looked at your photos

I always like to look at pics. Your boat looks good.
