Yup, not the same at all. But what I said about the SH knot meter still holds true. If I didn't have one, I wouldn't punch a hole in the boat to install one. My depth finder is a Garmin, combination GPS, depth finder. Split screen. Works great. Transducer is a puck type, which is mounted about one or two strakes to port of the mast support, under the forward bunk (right in front of the battery box). I just made a puddle of silicone rubber and stuck it in place. Works very well shooting through the hull and no holes to leak. In my opinion, the charting depth finders are a big plus over just a digital depth gauge. Once you know how to read them, you can tell a lot about the bottom you are over (rock, soft mud, etc) and if snags are present. A big help when anchoring. The other thing that surprises me about this GPS unit is that despite having an internal antenna, it still picks up the satellite signals inside the cabin. I thought that required a clear line of sight to the sky, but maybe not. And that was supposed to be SOG (speed over ground), vs. COG, which is course over ground. Senility strikes again.

Hi Howard,
I guess I should have mentioned that the standard horizon instrument is a depth sounder. I already have the transducer removed from the boat, the adhesive had dried out and cracked and that was what had caused the leak. All of the old marine adhesive has been removed and I have cleaned everything with MEK. I will pick up some 4200 tonight and re-install. It was actually easier to remove the through hull then I had thought, the previous owner must not have used 5200. That stuff would have made removal impossible.

A digital knot meter? Mine has the Standard Horizon analog. It never worked right, so I had SH ship me a new sending unit (little paddle wheel). Still doesn't work right. If knot (pun intended) for the two holes that would be left in the boat, that could go overboard. With a GPS on board, the only advantage I can see is if you are bucking a tide or current, you might be able to figure out how much from the difference between what your knotmeter is reading (speed through the water) vs. the GPS COG indication.
Anyway, the way that is installed is a plastic sleeve with a flange that should be very tightly caulked to the hull. The paddle wheel fits through that sleeve and is held in place by a clip. The only seal as I recall is a rubber O ring. A bit scary when you think about it.....which I haven't for some time....but mine doesn't leak. First place to look for your leak might be replacing the O ring, with maybe some Vasoline to help lube/seal the new one?
Beyond that, if you have to pull that flange off, it all depends on what they put it on with. If it was 3M 5200, you could have trouble getting it off. Others would probably yield to some steady pressure.

Hi Phil,
Congrats to you as well on your new boat. As with any boat new or old there is always work that needs to be done. On our boat we went through the rigging over the first two evenings since we brought her home. After replacing a couple of items on the standing rigging we decided everything looked reasonably sound and took her to Lake Pepin to see how things worked. The first thing we found that needs immediate attention is a leaking through hull. Fortunately we didn't sink and we were only going for an afternoon sail more as a shakedown cruise to find what needed to be fixed. It is better to find things like that out now then on day 1 of a week long trip. We were able to meet up with Bones and had the opportunity to see his beautiful Monty 23.
Anyone have any good advice on removing an old transducer and re-bedding it? The instrument is a nice digital Standard Horizon that seemed to work fine. I hope not to damage it during its removal.
Thanks,
Chad

Chad...congratulations on #259. I just purchased 1977 boat #250 a few weeks ago. Maybe we can exchange problems on a boat of this age. I have some fixups on this boat as well. The name on mine is <Puffin", which I would like to change if it can be done without angering Neptune.

Hello everyone,
After lurking on this list for well over a year, and even asking if I could join on one of the rendezvous with a com-pac I am happy to say we are the new owners of a 1977 Montgomery 17, hull number 259. She has a yellow hull and has the small galley installed. We are in Minnesota so this winter will be spent doing some maintenance and upgrades and possibly at least one trip south to escape the winter blues.
