homemade jobbie for river/pond/smooth lake fishing.
paddle boat, 6.5hp 10 tooth clutch, 14 tooth on the prop (have a 10 tooth to swap out)
6.5x4 weedless prop
3/4in keyway shaft (14in length)
1800rpm clutch, 2mph right when it engages. 4mph wide open (just under 3500)

what can i change to get a couple mph more?

Wow...

WOW and strapped to the top of a town car!!!!!!

Can we nominate this for photo of the month?

Somebody buy this man a beer!!!!

That is doing what ya gotta do fo sho!

Speed??? Well id change the hull for starters.

Try a different prop

lol

@ $135 for a prop, its going to have to stay.
if 4mph is all i get, then so be it. im going to try the 1:1 gear and see what happens today.

i had strange looks and some thumbs up when i took the interstate to go fishing (before the motor).
ol stinkin lincoln's paint has faded so it doesnt matter lol
i put a 302 long block in the truck with the upper intake off. very versatile car

I bet u could peddle that boat at least 4 1/2 mph if u take the mm off the back of it.

I just looked at this pic again and started laughing so hard I cried!

I hear ya! Put duals on the back and drive it like you stole it!!

LOL! I bet if you get some black death stickers that would put it at LEAST 15 mph.... I've always heard from people that built there own surface drives that there is a lot of tweaking with gear ratio and prop selection. Thats dedication... reminds me of the days when I had an 8' white inflatable with a 5hp merc outboard to go duck hunting with... what used to take me 2 1/2 hours to run now takes me less than 15 minutes.

That sea hawk sticker must mean it can fly

you guys are a trip.

Good for you!!! Thats makin lemons into lemonade!

Make a 4 foot long exhaust pipe straight up with a flapper on it!

damn.. lol
should have went with a belt drive! wouldve had more speed
also should build a frame around the chain, it will add more speed becuse the durability for the shaft

heres a thought- the paddle thats under the boat thats attached to the pedals inside- maybe thats causing alot of drag

also-i see that auger prop, isnt that for a longtail??

No. Two different props. A lt prop is made to run submersed.

I've seen a couple homemade motor frames come thru here, and I must say you get a A for effort on that one.

As far as why it wont run: 1) your chain (and metal plate in front of it) is about a foot and a half too long. Take a look at any of the belt drive/production models, the belt box is about 5"-6" above the bottom of the boat (and not draggin in the water, causing a disturbance to the prop). and 2) as Autogate man said that is the wrong prop. A longtail prop is made to run on a longtail (submerged and not geared down).

The picture of it on top of the car needs to be the picture of the month. Classic.

Well ~ The way I gots it figured ... you gittin' 0.62mph out of each HP .... PD gits 'bout 0.76mph from each ... Gator-Tail gits 'bout 0.85mph out of 'em .... course these are all stock style engines on the rite hull application ..... if'n you could up-grade hull .... you mite be surprised on yore results !!!!

BTW ~ Nice job !!! And yore rite 'bout the Towncar .... gots enuff turtle hull to stuff a D9 in !!!!

Good job man, that's definately a first. That thing is kinda cute actually. And I'm sure it beats the hell out of having to paddle!

I just noticed the base is welded to C-clamps!

Now I've seen it all!

Make damn sure you roll them windows up in your pimp mobile when you are launching your boat!!

LOL

Wow. Just wow.

Is it strapped to the roof with the seatbelts looped through the doors?

not bad at all. and at least you are getting a rooster tail out of it.

Thats just plain awesome.

I'm thinking just a couple things about these videos: no parental supervision with big dreams; great combination for either sucess or disaster. You have had one of those "I have an idea" moments.
