You can cut that angle with a skilsaw and a standard carbide tipped blade. I installed aluminum patios and carports for many years and that was all we used. Great vid, thanks!!
Hello Michael! I'm in the same debate now as you were, but with an 14' RIB. Its transom calls for a 15" shaft, but my Yamaha f9.9(which I couldn't pass such great deal on) has a 20" shaft. So, I need a small jack plate to raise the motor at least a good 5"-6". btw.. in regards to your question about the proper height of the motor, my Yamaha f9.9 manual states: "Mount the outboard motor so that the anti-cavitation plate is between the bottom of the boat and a level 25mm (1") below it." Thanks for the video!
Nice tutorial Mike. Life will be easier for you and your fabrication more accurate if you get a bench top drill press and a porta band saw. Both available at Harbor Freight Tools and they go on sale often enough or use the 20% off coupons in the mail. The cavitation plate on the outboard should be even with the bottom of the transom.
Hello, I’ve watched this video several times and later watched you install a CMC plate. Could you describe the difference you have felt or your overall decision?
I just use old wood blades. I say old because it will dull a new one quickly. Some people flip the blade backwards. I just let er rip. Just as fast as it is loud, and boy is it.
I just put my Johnson 9.5 hp on my 14 ft Meyers aluminum fishing boat and I took it out for the first time yesterday but it won't plane and it doesn't feel like it's meeting its full potential.... And ideas? Thank you for your help man enjoy your videos and so much great info.
Been watching for a long time, sold my 96 bass tracker and got a 1448. Been building and love this mod. A test and tune video would be cool! Also how does the hydrofoil work for ya? I also think it’s AWESOME that your doing all this stuff WITHOUT all the fancy tool, drills, saws ext..... doing more with less is a great way to do it!!! 👍👍
That's really good. I need to do one since the transom brackets on my Mercury outboard won't fit on the aluminum transom of my 1448. The person who had it before me put an extra thick transom cover over the original transom.👍
I appreciate you show the process including the mistakes. It makes me feel less dumb when I make them :) Did we ever find out what size and thickness of the aluminum? I'm guessing 3x3 and maybe 1/2" ?
I was wondering the same thing. It's hard to tell from the video. I'm just guessing his angle is more than 3"X3". Possibly 4"X4". And less than 1/2" thick. Maybe 3/8"? Or even less? I have a store bought jack plate of the same design and it's 1/2" thick. But it's for a 200hp motor on a boat that weighs 2,000+/- lbs. So 1/2" would definitely be plenty for a 100 lb 15hp motor. I'm thinking of building a plate for my 14' skiff and 100lb 20hp motor with 3"X4" angle 1/4" thick (at least that's the plan so far. It could change ;-).
(I’m doing my first boat) So the cavitation plate is the horizontal fin (black) on the lower motor housing and you want that on the same level as the bottom of the boat? - How thick was the aluminum angle? - Stainless steel hardware or aluminum? Stainless Great video. Damn, something else to check into on my boat!
Looks functional, great work, for every inch you move it back you should go up also, built something like this for my jon but it’s hydraulic tilt as well
In the future you should use s bracket aluminum and add plywood or aluminum to the mounting area to increase width and strength. You can purchase an all metal one for around $100, although I like the idea of building it yourself.
Is it possible to put an electric tilt and trim on the back of a jack plate? I have a 1548 g3 and the previous owner welded and bolted a jack plate to it. It sticks out kind of far and the bottom of it is open, on the launch it creates back pressure. I don’t like it lol. I was thinking about welding another piece on the bottom.
Awesome video. Thanks for sharing. How thick aluminum should I use? I have a 25hp in need to raise about 6 inches. Do you think 1/8 will be strong enough?
What's up Mike, cool vid bro I dont have a motor on my 1436 Jon boat yet , ( can't afford one just yet)) but my question is how would I know what length I need to get on a trolling motor for my boat? I'm a first timer and I'm sanding and sealing before painting and um getting a trolling motor for fathers day but I dont know what length shaft I should get for the best efficiency can u help me?
I love this idea!!! I want to do something similar on my 16' Lund. I can't find that size aluminum angle anywhere except special order and 20' minimum... If you have a resource I know many of us would love to know. Thanks for all the awesome videos!
So I have a older motor and the water intake ports are above the cavitation plate so does it still set up like a motor where they are below the cavitation plate or does it need to send Neighbor in the water?
Interesting! How heavy of a motor would something like this hold? Also, what is the purpose of angling the bracket? Did you think about aluminum welding plates together with that aluminum "brazing" rod? Lastly, did you consider cutting the height adjust holes oblong so you micro-adjust it? May help. Great idea & video. Thanks!
I would also fit from the transom a couple stablizer bars to side of the boat to make it stiffer if it ever hit a rock it made to my tourqe a little over engineering might help I’m putting a 7.5 hp on a 10 foot jon thanks for your video
So question. Why would my exhaust port be coming out of the water at speed? First time it happened i thought some gasket blew out. But i let off and nope. Went back under water and back to normal sound. It's only a 6hp short shaft. It doesn't happen all the time only when trimmed down.
A lot of youtubes say level the cavitation plate with the lowest point of the keel. Problem with that is that every boat I know of that lowest point of the keel goes under the waterline when you are in the boat, right? So, that would put your cavitation plate under the water, which is not what we want .
Don't they make a 15 inch engine for these 15 inch transoms??I just got a new Suzuki 6hp, thought it was a short shaft but its about 18 inches to the cavitation plate
Nah, I'll just find a 15 inch shaft engine. Don't need all the weight and leverage that high throwing of the center of gravity and stressin what little bit of transom I got.
Hell ya man I just started to bild one after watching your awesome video thank you, I wish I could sed you a picture all I'm writing on is a piece of flat aluminum to finish it off, hell ya also I need to join the TBN team start up a chapter out here in Oklahoma
What would you do differently on this build? How much wider would you go for your plywood would 12" work better? When you add the plywood would you go ahead and add two peices to it?
@TinyBoatNation wow. Big fan of your videos. Watch a lot of them. SIMPLE question to answer! Have bought a lot from your company. Didn't know you were such a dick. Now I do! Wish I could return the crap I bought from you! Ignorant jerk you be!
It's been a few months since you made this I need to raise a long shaft 5hp up about 10". Aluminum is soft so I'm wondering how you're held up and the size of the angle iron you used
@@TinyBoatNation I picked up a drill bit one time it at a friends house it was very toasty burn blister toasty i threw it down quickly. my friend snickered and said hot ain't it? I said ........ NO it just don't take me long to look at drill bits, he laughed his ass off for 5 minutes, he has never heard that one before, I supposed you haven't either.. the original joke is told about a horseshoe at a blacksmith shop.....
What size holes for the mount? How far apart are the adjustment holes? more information on how to build would be great.. I'm in the process of building a jackplate and watched your video several times trying to figure out the hole size and spacing.... great job though
Looks like you just need about a 4’ piece of aluminum angle and a ~12”x12” plate and a couple scrap pieces of plywood. Throw in about $20-$30 for 12 Stainless bolts, nuts, and washers.
Can the amazon jack plate be used reverse to lower the motor? I have a 14' Fisher 1998 bass boat that I am redoing. It is in excellent shape but I am converting it to a tiller style boat. Meaning I'm taking off the 25hp Mercury and the steering console to put a 9.9 motor in it so I can fish the small lakes. The 9.9 I have is a short shaft and my transom is 21 inches. My motor length from the place it rests on the transom to the cavitation plate is 19 inches meaning the cavitation plate sits about the bottom line of the back of the boat. Any advice?
@@TinyBoatNation Great answer, way to belittle a well-meant warning... You obviously have quite the following, so even though the odd exposure to epoxy is "survivable", epoxy allergies due to continued exposure are very real and perhaps worth passing onto some of the people whom you influence.
It's a crying shame that somebody doesn't just make a lightweight, pressed aluminum jack plate especially for 60 pound or less, 6 HP and down outboards. It could be along the lines of the Mini Jacker, which is super-thick and heavy cast aluminum, and rated for up to 150 pounds and 35 Horsepower, and is therefore brutally over-built and expensive for 125 pound inflatables and 12 foot aluminum jon boats with a single cylinder, 6 HP and less outboards. If I had the means I would press some out of 3/16 sheet aluminum and make a fortune.
Instead of wood you should have used plastic cutting board. Kinda silly to ask us HOW YA DOING in a video... Maybe next time just say hope you're doing well!
You coulda just clamped a board to the top of the transom and hung the motor higher. Its a 15 hp portable motor. There is no need for all this. Its not a performance motor or boat hull. At the very least you could get the motor to the height you think it needs to be and test ride it..
You don't pay 50 dollars for a McDouble from McDonald's. Why waste time and money with a jackplate on an unmodded 15hp motor. He coulda raised the transom in five minutes if he wanted a marginal speed gain
Imo small boats are about how slow you can stay on plane and cruise. And how shallow you can go. Its not a speed machine. Slow efficient cruise and shallow ability is where its at

Crazy! You lifted that motor off like it weighed 20 lbs. Nice plate. Too bad I already put a mini jacker on my inflatable catamaran.
I can’t wait to see how the boat goes now.
Hello,
I’ve watched this video several times and later watched you install a CMC plate. Could you describe the difference you have felt or your overall decision?
You really need to invest in a mitre saw and aluminium blade. Makes cutting take a second rather than 30 seconds a pop. Best investment I ever made.
I just use old wood blades. I say old because it will dull a new one quickly. Some people flip the blade backwards. I just let er rip. Just as fast as it is loud, and boy is it.

On the fly jack plates are great, but they cost around $600. However, they are fully variable and you can adjust them as you are running the motor.
Watching you grab the hot piece of aluminum hits home :)
Jack Plates are really expensive. Great low cost idea!
I appreciate you show the process including the mistakes. It makes me feel less dumb when I make them :) Did we ever find out what size and thickness of the aluminum? I'm guessing 3x3 and maybe 1/2" ?

You have to lift the engine up a little more. Never seen this `mini jack`thingy... we just build up the transom.

Too high out of the water
When cutting Aluminum you can use a Skill Saw with a woodcutting blade. I did this with 3/8 Aluminum but I saw on youtube cut a 1-inch thick aluminum.
Thank you!

Problem with that is that every boat I know of that lowest point of the keel goes under the waterline when you are in the boat, right?

Not when you are up On-Plane at speed - which is also where you want it to make the biggest difference!
Again, Great Video. thank you so much!

I don’t remember, but aluminum gets more expensive by the day so
What would you do differently on this build?
How much wider would you go for your plywood would 12" work better?
When you add the plywood would you go ahead and add two peices to it?
Did the plywood not hold up?
Practice make perfection. I'm on a complete build atm and its getting very pricey. That's why I'm making my jack out of scrap I have laying around
Would this work for my 30 hp
