I am glad I was able to give you an idea. I have looked for that style u-bolt with out luck. When I saw those I wondered where you got them.

Great Job!. Where did you get the u-bolts?

Great.

Personally I would get the simplest motor available. That would be a 5 speed with cable steering. If you rely on it daily the less things it has the less likely it will fail.

Is there an Update? I would like to see what you have done?

Interstate and walmart batteries are both made by Johnson controls. There are only a few companies that make batteries for all other brands. http://batteryfaq.org/

I had the trailer out for a full load test today. Hauled two OK prowler big games and a small pelican apex 100 it perfomed well. basically what is in the picture and another kayak like the blue one.

Yes, you can replace the knobs, they have a nut inside, with a regular nut. It is a carriage bolt that comes through the bracket. I may, at a later time, remove the rollers and bunks and get two more sets of J brackets and have the capacity to carry 4 kayaks.

The ones I have clamp on the pipe, or roof rack, with two big plastic knobs holding a piece of metal.

I found these on Amazon. http://www.amazon.com/TMS-KAYAK-RK-J-1BOX-Universal-Carrier/dp/B003V57NUQ/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=1VVAF8GQHY0H2&coliid=I2HOXIY7TY818Q

Oh, yea. The J cradles are much easier to use. Yes, they are carpeted 2x4s. they came with the trailer. http://www.harborfreight.com/600-lb-capacity-boat-trailer-with-8-inch-wheels-and-tires-5002.html I had the trailer for an old 12' boat i had. I got the blue kayak and got rid of the boat and kept the trailer for the kayak. Then another kayak for the wife. So I had to make modifications. If I had the kayak and then needed a trailer I would go with this. http://www.harborfreight.com/1195-lb-capacity-48-inch-x-96-inch-heavy-duty-foldable-utility-trailer-with-12-inch-wheels-90154.html and bolt the J brackets right to the cross members. If I started over

eBay. $49.95 with $14.95 shipping.

The cradles were $65 total for all 4. The EMT is held to the trailer by straps. I also put a screw through the top of the strap into the emt to make sure it doesn't slide.It is not going anywhere.

Wanting to haul more that one Kayak at a time easily when I kayak fish with others I made updated my trailer to do the job. I took by existing harbor freight trailer, some 1 1/4" EMT, 4 two hole EMT hanger, screws and kayak carriers. I may shorten the pipes to pull the outside kayaks in a bit.

2001 Crestliner Angler 16. about 4k new with trailer. paid Cash. Literally handed the salesman $100 bills. Nothing out of the ordinary as far as costs. repack the bearings every other year or so. Water pump now and then. Biggest cost if fuel. about 200 a year locally about $150 for the week I am in Canada. heck insurance in about $100 a year. I did have to replace the tilt assist cylinder twice in the last three years though.

Charger http://www.allelectronics.com/make-a-store/item/BC-201/12VDC-1000MA-DUAL-STAGE-CHARGER/1.html batteries http://www.allelectronics.com/make-a-store/category/160/Batteries-Rechargeable/1.html

5 speed trolling motors will not cause interference with a depth finder in they are hooked to the same battery. Find out what the max current draw for your motor will be and wire and fuse accordingly. 6AWG and a 60 amp breaker will be good for most motors. For all other accessories. I would would run a 10 AWG wire, with a 30 amp breaker, from the battery to the main post on the fuse block. On the fuse block I would run 14 AWG wires with 15 amp fuses to pumps and other heavy loads like accessory plugs. The I would run 16 AWG wires with 10 amp fuses to all electronics and lights. I think Humminbird wants 3 amp fuses on their finders. I would still run the 16 AWG wire so you wont get voltage drop.

My 12V 52lb thrust minnkota only draws 30amp at top speed.

I use one of these for my Kayak. I am sure a canoe would fit as well. http://www.harborfreight.com/600-lb-capacity-boat-trailer-with-8-inch-wheels-and-tires-5002.html

I used some 3M VHB double sided tape to mount my transducer to my aluminum boat. No issues. You have to get the correct stuff. I mounted the transducer to a piece of plastic then used the tape between the plastic and the hull. I got the idea from humminbird. http://store.humminbird.com/products/313992/XSO_9_20_T

The act of sucking air from the surface of the water is called ventilation. cavitation is when "bubbles" form on the low pressure side of the prop.

Pure 12v DC. they also have 24 and 36 v versions http://www.alten-dc.com/gasoline-powered-dc-generators/item/106-12-volt-55-amp-gas-powered-battery-charger.html

Any Update to this project?
