Sears 1436 Build

Post by Drothgeb » 30 Oct 2019, 07:53

I’ve been really busy lately, but finally got a chance to apply the final coats of “Monstaliner” to hull. Monstaliner is a truck bedliner material that stays pretty flexible after it hardens. I did it for scuff resistance, to ensure there’s no leaks around the rivets, and it looks cool too.

I sandblasted the surfaces, then acid etched, then a couple of coats of DTM epoxy primer. After that, I rolled on a few coats of Monstaliner, then used a undercoating gun to splatter on a couple of final coats. Ended up with a nice rugged texture. On the bottom of the boat, after rolling on the Monstaliner, I applied a number of coats of “Gator Glide”. It’s a slick coating meant for air boats. It will help with sliding the boat over lily pads and vegetation in the lake and, it makes it easier to unload and load the boat on the trailer. Might even pick up a mph or two at wot.

This morning I decided my front trolling motor mount was a little heavy, so I made another one out .090” aluminum. Much lighter, and seems to be plenty strong for a trolling motor and anchor roller. Only a few more things to do, and I’ll be ready to install the decking.

All good. Still have my Sears 1436, 1967 or 69. Your work is inspiring.

I got started on the carpet over the weekend. Just using the cheap stuff from Home Depot for now. Hoping to switch it out with vinyl later on. Still have to complete the control and steering cables for the gas engine, but it’s now ready use with the electric motors on the local lakes. Considering the drop in temps lately, I gonna wait til it warms a little before I get it wet.

Fantastic build.

Curious to hear how it handles and performs.

You have effectively build a tunnel hull boat. With enough power that thing has the potential to really fly...but that does come with additional risk once that tunnel fills up with air.

Would love to see some side shots at speed.

Find you a Tohatsu Mega25 motor and this will be a common site when you are headed to your fishing spot.

Where do you mount the rod holders and down riggers?

I managed to get the boat on the water a few days ago. This was on a local electric only lake, so there’s not really that much to report. I was a little concerned about the weight that I’ve added but, the extra buoyancy from the sponsons made up for it, and the waterline is more of less where it was before the mods. On the plus side, the extra weight and sponsons made the boat much more stable than before. I was easily able walk around the perimeter of the platform (I’m about 170lbs). Definitely worth the work performed.

With both trolling motors wide open, I was able to reach a blistering 4.5 mph. Not bad, but not quite enough to get any hydrofoil effects. At this point, it will probably be early next year before I can get it on the river with the gas engine, and really see how it performs. I’ll check back then, hopefully with some video.

Not bad at all, Haha.

Glad to hear that the sponsons really paid off with improved stability. I look forward to hear how the hull performs when you get it out with the big motor.

It's certainly hard to believe that is only a 14/36.
It looks much bigger in the pictures.
I wish I had your skills. The boat and decking looks REALLY nice!
With that 25, it should do somewhat better than 4.5 mph! LOL

Nice job with the sponsons. I think, if you had 10 trolling motors, you would still not get over 5mph. The prop pitch on trolling motors aren't made for speed. If someone made a replacement trolling motor prop with a higher pitch, you would get more speed - but I've never seen such a thing.
