No way that I know of to tell you unless you have a friend with handheld GPS or know someone with a boat with a speedometer who is willing to "clock" you - although with a 6 hp a calendar might be a better tool....just joking with ya'.. grin.gif

Have fun with it and be safe!

Any working GPS would do the Job, Lowrance, Garmin, Maggelan all have small hand helds for around a $100.

I've seen plans to make a speedometer using something that looked like an upside-down protractor with a stick or string that would go in the water. You'd hang the device on the side of your boat and the drag would move the stick or string and where it crossed marks on the scale would note how fast you were going. You could make one and calibrate it to a known speedometer.

H20 non color is a good unit. I got mine used for $100.

Ditto on the h20. Add a Navionics or Lakemaster chip, and it doubles as your "depth finder" as well, or pretty darn close. Works great for ice fishing as well.

handheld is the way to go... and then you have it for many other uses as well...

For electronics I recommend an Eagle 320 depth finder with the speedometer and water temperature option. It's worth saving up for. It's not very expensive either.

I clocked my 14' aluminum with a 25 horse at 27 mph on a calm day with two of us, using a Garmin Etrex........kind of cool to find out how fast it goes.

Thank you for the help guys.

What is a calender and how does it work for checking speeds?

I checked out the H20 the local sports shop only had color and that was 279. with another 100+for the chip for it.

The calender was a sarcastic remark,refering to how slow a small motored boat travels.I just went along with it,And you should check out used GPS units,try them then decide later if you need more bells and whistles. shocked.gifcool.gif

A buddy of mine picked up a new H2Oc w/ the chip during the ice fishing season and it is incredible. I picked up a used magellan unit for $50. Its not nearly as nice, but works for what I need it for.

I plan on getting one just probably need to get back to work.

I picked up a eagle cuda 168 depth finder with temp. I wanted a fish finder depthfinder temp thing also so will go with this for now. at least it shows the structure of the lake and will make it a little easier for trolling and i thats what i want to get into. i can quess on the speed for now. if there hungry they will bit. by the by i did catch a 20" 4+lb bass yesterday just drifting with a sucker minnow. thank you guys for all the help.

I clocked my 14' with an 18hp on it at 23 mph with one guy in the boat. Three people in it I can get 14 mph and a nice bath while driving!

Then when the motor dies and you get pulled in by a crazy man it can probably hit 30, but I wouldn't know I was hanging on for dear life! (True story)

I have a 16' lund with a 35 and a 6, with the 6 I can get 5.3 mph, so your 14' would probably be around 6-6.5 I guess.

The original hand held Garmin 12 should be very cheap. I bought one at a pawn shop 6 or 7 years ago for about $70.00, now a days with everything "map" you should be able to get one under $40 or $50 bucks. Maybe even less.

I figure GPS speed is more acurate than the distance in feet from your way point. Anyone else know?

      Hit the lake before 6:00 this morning. Fishing very slow again. Lots of mayflies on the water. Water 64 degrees. Got a bass at first stop but no more of those. ABout 5 walleyes and four pike in nine hours. Quit just in time to fight the 22 MPH wind (twice what was predicted) all the way home. Fish in 25 FOW. Most on Fin-S-Fish. numerous missed bites. Yesterday hardly missed a one. Not so today.   June 27, 2017 video link

      Froggin is a blast! I couldn't get any topwater action Saturday but just under the surface with a spinnerbait they were crushing it. Early morning it was suspending jerkbaits on weedlines. Not a single swirl on top.

      The walleye bite the past couple days has gone from Boom to  almost Bust! There have been a couple of huge May fly hatches the last couple of nights along with a large Rusty Crayfish molt that have been making catching walleyes a real challenge! We are still getting some fish but now have to earn every fish! Lindys with 1/2 crawler fished VERY slow in 18" to 30" depths has been my best presentation. Cliff

      Thanks guys!  We tried kayak fishing last year (around Labor Day I think) and the Rum was way too high.  We launched on CR 7 between Blue and Green lake and just ended up paddling the river.  Is that a good stretch for smallies?
    • ANYFISH2
      wow, that is one dark walleye!

      And no reports make forums no good. Participation is what makes this place great.   Do not discourage that!

      Decided to fish Big Detroit saturday with a buddy.  Had bites but my 24 v 75#  trolling motor couldn't keep me in place so that sucked.  When we left the access to go fishing I asked the young man how late they were open till so I could make it back in time to get washed since I was going to fish a different lake on Sunday morning with the nephews.  I will be here till 5:30!  Sounds good see you before 5!  Fishing sucked, Wind BLEW, RAIN SUCKED!  So we packed up at 4:30 drove to access get there around 4:40 and they are gone!  Hot on my heels is a local fishing guide and he wasn't happy also because he had the same game plan.  Was told that there would be one at Melissa till 5 pm religiously.  Got there by 4:55 and they were gone from that lake too.  I honestly don't feel comfortable enough to do a safe job washing since I don't have a pressure washer and I really don't want to spread the Zebra Mussels from lake to lake and I know it was only a few hours 5-6 but honestly whats the point of AIS being there if they don't stay till the house they are supposed to be?  There was an easy half dozen boat trailers still at the access so it wasn't like we were the only two left at the access.

      Had some fun Saturday morning crashing through the lily pads on a small metro lake.  2 fish over 5 lbs and every fish absolutely choked the bait.  All I want to do is throw top water now, haha.  Wish I had longer arms or a partner in the boat for a decent photo.
