    Intex Mariner 4 modifications and Tips

    I see. There is no impact force though, since I have spacers ( well, a layer off tape on one, and some heatshrink on the other since I ran out of tape ) the pipes can not rattle around inside each other, this is also why they are welded on one end. . If they could, I would be afraid of fatigue...

    You can't use a single thicker piece, it a> won't slide into your plastic motor mount b> won't slide through the backtube mounting hole. Though (b) isn't really that important if you properly secure the ends at the oar holders, you will need to use the stock pipes *what you see are the stock...

    Intex Mariner 4 modifications and Tips

    I couldn't source alu piping at affordable cost, so I first only used the inner rvs which I just got from the hardware store ( plumbing rvs pipes ). That ended up bending on first use, guess having only 1.2mm wall thickness doesn't help. And I think that's both the inner as the outer pipe's...

    I mentioned it because I have one of the converted weed wackers and I can't stand using it. Mine is only 1.1kw though and 9kg so comparable with my trolling motor.. with much more range, just the noise is unbearable can't even speak with other people on the boat. It's a 4 stroke, for the same...

    https://forums.iboats.com/threads/intex-mariner-4-modifications-and-tips.534660/post-5785629 See that image for what I mean with extending the mount to the where you normally attach the oars when not in use. I can still use those oars normally, it's not replacing the oar mounts just the oar...

    Extend / reinforce the motor mount so it reaches the oars and use those to stabilize the mount. There are pictures of this in this thread. That and spreading the load on the bottom using some wood as you did should reduce sag of the mount more then enough for a 3hp since it's enough for my 5hp...

    The bowing happens because the keel pushes from the centerline underneath and the floor is held in place there by the tubes above it so from the sides and not the middle. A to thin floor will bend in the middle right where the keel is pushing up. On the thickness you need, that's entirely up...

    The slated floor has very good structural rigidity, try bending one of those plastic pieces. Which is why it's so heavy for the most part, it's not a hollow beam it has structural infill. I think a wooden floor makes most sense if you build on it, eg you build your seats on the floor, add a...

    My previous boat was the Excursion 4, I have a folding wooden floor for that ( three sections so I could transport it ). As neither I nor my kids are heavy we did't need a thick floor to be able to stand on it. But as others have pointed out, if you leave out the slated floor you can't inflate...

    Use the slatted floor which came with the boat, put it on top of your wood and mark the edges.

    Adding insult over injury, my CN ebike manufacturer just send me an 'important email'.... announcing why they don't the battery I want in stock.. The proud release of their next model, which ofc comes with different size batteries.... I really hope you can source that cap somewhere, this is...

    I found some airdecks which seemed to match the shape of the Mariner 4 close enough that they would work, but they all lack a throughhole for the keel valve. And you can't inflate the keel before you inflate the airdeck. Then I found shorter one's, probably short enough so the keel valve would...

    I seen a 25hp used once in a video but that didn't have a 'a floor' but an entire wooden floor+seat+console+motor mount all connected in one piece. As to 'park rangers' -> forest rangers around here ( Netherlands... not your neck of the woods ) don't enforce anything except noise laws ( so...

    Afaik the right one is the old model, other one off course then being the new model. I have no clue why there is a price difference, seems 'fishy' if you ask me. I have the blue one. Material wise, there shouldn't be much difference except what you pointed out. The spec sheet didn't change at...

    Thank you, if it's meant for me lol. Don't take anything as say as being 100% right, my experience is extremely limited. I am actually counting on more knowledgeable people to come in and correct or supplement me. I've found video's with Mariner 4's going way faster, all with wooden frames...
