My 86 came with a digital knot meter and depth guage, the knot meter has a broken lens. Is this a "stock" item" or something the prior owner added? Any idea where a replacement, or repair could be located? Any help is greatly appreciated.

Your knot meter most likely did not come with the boat from the factory.

What brand and model is it?

If it is fairly new, which I doubt, it may be compatable with a newer model display from the same manufacturer.

If not You may try e-bay.

Or as a last resort you might try Bacon's in Annapolis.

Good luck!!!

I found out today, it is a SR Mariner DKT-5, I looked on the web and found they do repair for a fair price, just have to remove and ship it to NY. Thanks for the help and interest. I guess it is a fairly expensive add on, along with the digital depth sounder, I guess I did okay at the auction on this boat.

I refurbished both a knot meter and depth meter with them. They went throught both units (neither was working at the time) and replaced the sender for the depth meter and helped with emails on the installation plus sent new installation guides for the very old instruments. About $130 including shipping.

I have an SR Marine knot meter that only works about 10% of the time. I believe the problem is with the sending unit that has a few damaged vanes. What is involved with replacing the sending unit?

I replaced the paddle wheel quite easily. Mine was a through hull. Check the manufacturer for a replacement part. There are little bits of metal embedded in the paddle wheel and they had corroded and fell out.

Thanks for the response, Paul. I went to their site but they have yet to respond, which seems contrary to all the good reports in the above messages, I'll try again.

I also have the through hull sending unit. In replacing the paddle, do you tamper with the through hull seal at all, or is it just an external mechanical job? Exactly how did you remove the old paddle wheel?

The knot meter has a threaded cap on the inside of the boat. You unscrew the cap and pull the guts straight out (there is an alignment bump). There should be a plastic stopper that can replace the knotmeter and allow you to reinstall the cap, making the unit water tight again. If the boat is in the water, and you have the stopper, you can pull the knot meter and install the plug with only about a quart of water getting into the boat.

Michael:

The boat is on a trailer, so incoming water is not an issue. I asumem when you say "knot meter", you are talking about the through hull sending unit. From your description, it sounds like there is a collar sealed to the hull, and the unit is locked in place, water-tight, to the collar. If that is the case, it sounds easy. Just buy the new sending unit ($54) and run the new wires that come with it.

You've got it. Toughest part will be releading the wire from the sending unit to the display. I suggest you use tie a string to the one you are removing so you can pull the new one through.

My knotmeter stopped working and I read that the first thing to check is whether the little fan/w/magnet part under the boat is clean and moving - the transducer? I want to pull the transducer to clean it while my boat is in the water. There is no extra push-in seal to stop the hole while I clean the transducer. The company that made the knotmeter - SR Instruments, Inc. is apparently out of business. I see that the knotmeter is Model KM5A, specified on many Catalina 22s. Does anyone know the circumference of the push-in seal I'll need to stop the hole when I pull the transducer? Or another method to stop it?

I have wooden plugs, available at any marine supply outlet, at each transducer location

Nancy, while it's not made anymore, you can still buy parts. Try this site: http://www.srinstruments.com/mariner/default.asp

RC, do you happen to know the diameter of the plug for the transducer? I'll also try that site for the parts. Thanks all.

Nancy,
I just saw a flexible foam plug at West Marine that might work. It may make a better seal than the wood plug. You are going to get a lot of water gushing in when you pull the transducer plug. I would just wait til your next haul out.

I wondered if I'd actually have the nerve to pull that out. Guess I'll test the rest of it and wait 'til it's on the trailer again for that part to clean the paddle wheel. Thanks for reminding me of the difficulty/stress factor.

Actually, the plugs come in a package of 6 and at least 3 of them would work for my transducers. BTW when you pull it out you should get no more than a pint or so of water in your boat. I pull my paddle wheel twice a season. Just have the plug and a mallet handy.

Thanks, R.C. If I get ahold of some plugs that look like they'll fit, I'll go for it. I live far away from West Marines. But a friend might bring me some when visiting.
