Speedometer repairs
« on: October 16, 2012, 03:48:43 PM »
Helo all,

I am new to boating but a long time Engineer/Mechanic. I bought a 1997 215 Explorer and have taken it out on the Great South Bay of Long Island and we had a blast. The boat came with a Fishfinder 160c and some minor issues with two guages, my speedometer did not work as well as my trim gauge.

The trim guage just needed a little white greese to loosen it up but after tracing the speedometer I found that the hose was cut at the transome.

I did some research and found that I can (A) add a paddle wheel type to my fishfinder 160c and (B) add the Pitot device to the back of my boat.

For the paddle wheel I drilled a 1/4 inch hole at 6pm position of the existing 3/4 inch hole that was already in place for the transducer of the fish finder. This allowed me to tuck the original tranducer wire in a chamber so I can push the new paddle wheel wire with it's 3/4 head through without having to drill another hole in the transome. Ran the wire along the stern to the starboard side then to the bow were I was able to piggy back the two connectors. If I spin the paddle I see numbers.

For the Pitot guage I had to trace the hose find the cut and replace the back half section as well as add the pitot guages off the back of the boat. I know this works because when I hit it with light compress air I see it move.

All holes were sealed with perminent marine grade sealent (3M).

I know theses devices are not 100% accurate but I hate stuff that doesn't work.

So this is the finished results:






What do you think?

Nicely done Melo!

I can't get a tight enough zoom on the picture to see any spooged sealant on the screws that hold the wire clamps, did you get them too?  :salut:

"Spooged"...that's a cool word!

Yes, I did put sealant on all of the screews even the ones that held the clips in place. I treated the sealant like thread lock that we use on our race engine ... I am way over board with stuff like that ...

I added a speedometer to my 17.5 a few years ago, but to be honest, I use the GPS for really accurate readings.
      If I had to spend the money, and the choice was a Garmin GPS or a speedometer, I'd go for the GPS.     I live on Cape Cod and many days start off clear and end up foggy.   I've counted on the Garmin to get me home many times.   I bought the hand held and the 12V plug and direct hooked it to the battery.  ez to mount and remove.  Ken
