  • Installation of trolling motor on 17' Four Winns Horizon Fish and Ski: DONE!

    Mounting a trolling motor on my bowrider was tricky because of the slopping, curvy gunhale and the railing there upon. The only flat spot on the bow gunwale was where the running lights are. So, this was going to require relocating the lights further forward and down a step.

    I cut a 6" diameter disc out of 3/4" UHMW polyethylene to raise the trolling motor base up past the rim of the bow seating area. This would also provide a low friction surface for the base to pivot on.

    In order to bolt the trolling motor base to the gunwale, I had to cut an access hole using my Rotozip tool. That fiberglass is hell on those spiral cut bits. I'll cover this hole with a deck cover from the iboats store.

      The old hole for the running lights was not in the right spot, so I drilled it out to 1/2" diameter, then epoxied in a 1/2" fluted hardwood dowel. After the epoxy cured, I drilled a pilot hole to keep the 1/2" hole I drilled next on course.

        I've got a good, stable pivot point now, but I needed a way to lock the base in place, so I bolted the UHMW disc to the deck, then drilled a 1/4" hole through the base, disc, and deck for a lynch pin I picked up at Lowes. I'm going to order a stainless steel one soon. I applied a liberal amount of white silicon to the bottom of the disc to seal out water and help hold it firmly in place.

          Here's the bottom side of the trolling motor base. I used a 1/2" stainless steel bolt as the pivot.

            Here's the base fully deployed, ready to take me into speckled trout or redfish heaven. The running lights will go on the gunwale below the base.

              With the trolling motor in the stowed position, it rests nicely off to the side, neither interfering with the railing, seating, or canvas cover.

              For ease of handling the base, I used a section of PVC pipe in place of the actual trolling motor.

                Don,
                Why are some of the images previewing as thumbnails and some are only links? I went through the same steps on each post.

                  Here are a couple more shots of the base with the relocated running lights.

                    Very nice job!! . If you have the pictures somewhere else on the web, I'd appreciate it
                    if you pm me the url. I'd like to save copies. I haven't fished in the last 30 years until
                    a week ago, but the old bug has bit hard! I'm ready to put a trolling motor on my BR
                    in the sig.

                    Also, what model Watersnake Assult did you get?

                    Thanks,

                      Thanks. Why don't you right-click on the picture and do save-as?

                      I got this Watersnake through Walmart for $299. Free ship-to-store. Best price for a salt water trolling motor I found. So far it looks like good quality for the price. It's the 55107, 12V, 54" shaft, 54 lbs thrust, tiller steer version.
