Electric Jet Ski Conversion

[inventorize]

Put in a Prius motor...

[onjoFilms]

Cool. Litium batteries will probably get you better power. Search for Litium Hawk and see the guy who made a trike. Apply that to this and your in.

I want to make an electric flying seat (water).

[420bitter]

why hasnt anyone done what I am going to do? strip engine and pump from hull, put 2 or 3 deep cycle batteries in its place, and attach a trolling motor where pump discharge used to be, cheap, easy, great for kids!!!!

[MW2PsychoRealm]

Just wait till that puppy gets some water on it. Then well see Fast it goes

[MrSuperJetski]

Don't let the future bite you in the ass. It is inevitable that electric jet ski's are the future of rec. riding. The 2 smokes are on their way out, thanks to EPA. In CA. 2 smokes are illegal. Then visit DiMora motorcars they sell a high end version and it has excellent specs. On the other hand Mexican associate tried to build one w/o knowing design or engineering....he failed miserably.

The biggest issue is the cost of S.O.A batteries. Eventually, they will come down in cost.

@MrSuperJetski I believe the only 2 strokes that are sold are the stand up variety, am I right?

[MrSuperJetski]

@BlackTipGP1200 Here is a link that demonstrates the wide, smooth powerband of the 4-stroke

[MrSuperJetski]

@BlackTipGP1200 to answer your question, IDK . The older cruisers had 3-cylinder 2-strokes, but todays PWC runabouts are 4-stroke.

[DJRuteOfficial]

i dont know how, but this sound is even cooler than a 2 stroke engine :P

[jjc032681]

It's all about the project dick-heads!...taking an idea and making it happen. Sucks it didn't work out man, but a cool idea nonetheless. 

[FriscoJarretts]

You can burn out the seals fro the prop shaft doing that. It uses water for lubrication.

[advthinker]

Wow aint it great! you can get jet ski,s at the scrap yard for free all day long here in fl. the little weasles only know how to burn up them expensive engines, running across the lake only to have the chicks laught at them for forgetting to take there exite!  That is a great project you have there and it seems to have stirred up the bottom feeders into a frenzy! dont worry you cant fix stupid! Check into a vfd and a 3ph motor combo. 12v=to 120v to 3ph output. offer,s move speed. +smaller wires

[kinetiknz]

Nice. Keep at it. Ignore the haters.

[cleanpowerelectric]

jet skis are a great idea for a conversion. If you haven't sorted out yet why you melted the battery terminal yet, get in touch with me and there's a good chance I can help you.

I converted an outboard motor using the same style pancake motor (Manta 30hp copy of Etek) and it works perfectly. check out my video of the conversion.

[porpoisefathom]

allenhawk-- there is a video of your jetski on ebay selling an etek

a vidoe of your jetski is used- first 30 secs of your vid and then about 40 secs of another, but can you tell me if the video is legit? Its also on youtube- under electric sea/bomba by afcmpc. if so this would be blatant misleading by the sellers of the etek engine on ebay..can you please advise on this? i will pm this same post to you

[EETechs]

@SaltLife750 You are an idiot. WOW. Maybe you should watch less TV of how Hollywood TV shows and movies show electricity killing people with all those special effects. I bet you think a 12 volt battery can produce an arc. LOL. Learn about electricity.

[amphotoact]

@SaltLife750 lol i hate electric power too. I find it perverted to use electric when we have something so much better.

[NiteTrain345]

@SaltLife750 you do not get that much water in a sit down jetski with a good hull unless you're doing something crazy and flip it over. A bilge pump would keep the average amount of water out but having the batteries in a water proof container wouldn't be a bad idea. BTW, most water that does come in from normal riding comes in through the air intake which you could plug up when running an electric motor.

[NiteTrain345]

@SaltLife750 yeah I know stand ups turn heads motherfucker, I own 2 superjets. They turn heads because they haven't been popular in large numbers for 20 years and people rarely see them. If this guy wants to build an electric jetski let him..Do you understand the word innovation? Do you think the first cars and airplanes were safe? BTW if you have a 750 kawi I'm sure you're getting a lot of top-shelf trim with that ride LOL.

[codemanrose]

@SaltLife750 Look at how many people dislike and reply to all your comments. Your a KnowItAll and a HUGE Flammer. Your annoying and a negative to the PWC sport. Let people inovate and be themselves. Little guy you are.

[therbertme]

Get off the keyboard and back into your canoo caveman.

[ironoarsman]

I love it!

[james4078]

i got my hands on a 27 volt dc motor that peaks out to 7500 rpms @ 5 hp, i put that into an old polarus 750 jet ski hull and melted the wire too. I have recently put in some new heavier wiring put have not tested it yet. the etek motor have the torque but not the rpms to get you moving fast enough. The factory jet ski motors have the higher rpms and the torque to go with them even if they are noisy and messy that is why they are there. Keep searching, someone will figure it out soon enough

[porpoisefathom]

@james4078all u need is a bigger engine that runs on 48-72 volts-something like a 10 hp at 3600 rpms...gear it if needed to higher rpms.

[EETechs]

@james4078 You relied on a DC system. Try an AC system and you will see just how insanely powerful an electric jet ski can be. That's if it does not flip you over into the water first. I'd say get the AC-18 kit to make a super deadly jet ski that would not be fun since it would simply flip you over every time you gunned the "throttle".

[cazouu36]

@EETechs it wont throw you. electric is great but motors produce high torque and typically lower rpms. a kawasaki ultra 300x will kick its ass to next week

[EETechs]

@cazouu36 Yay! You are comparing 300 HP to a motor that is 40 HP. Well it's good that you pick such a high horsepower jet ski....Btw, you are not the type of person that thinks gas engines develop more torque than electric are you?

[cazouu36]

@EETechs i absolutely believe electric has more torque. for a jetski you need high rpms with enough power to sustain those revs. electric cars though like the tesla roadster and X1 are bad ass

[evmocean]

all the W's conistonpowerboatrecords.co.uk

[evmocean]

tell you what bring your ski to the world record session in england at coniston / lets put them all to the test and see who has the fastest electric ski of all ,would love to see you there but if no one turns up to compete against me i will hold the record being as i am the only entery this year ..chat soon

[jasonvincent027]

how did you do the coupling?

[allenhawk1]

The coupling used the harmonic balancer (the big white thing at the end of the engine) and I had a 1 inch shaft threaded to match the engines output shaft. I then used a couple of bearings to hold the shaft and a timing belt setup to transmit the power from the motor

[allenhawk1]

Put in the water today. Goes about 6-7mph and melted down a battery terminal. Back to the drawing board.

[bobbailey111]

@allenhawk1 Well done for making the ski into electric anyway. I look forward to hearing about it as you make her go faster.

[evmocean]

@allenhawk1 maybe we mite be able to help you with that we also have an electric jet ski but we reach speeds of 20mph+ call on us for advice many regards EVMocean UK

[3DPeter]

i hope you get it on the water soon , because i realy like to know how fast it goes. I also can't wait until seadoo, yamaha and kawasaki come out with electric jetski's, because i can live without having to stop at gasstations, and without the engine noises. they could easely come out already, because with other electric vehicles, you go from a to b, but with jetski's you stay in the same area so you could easely take some exchangable battery packs with you that wil give you loads of extra hours

[ibpointless2]

what do you use to hold the batteries in place?

please more VIdeos!

[allenhawk1]

I use the same tiedowns for the gas tank with a 2x4 to keep it tight. I do need to move a couple of batteries to the back, so I will be using a steel plate and some nylon straps to keep those batteries in place. You working on a project too?

[ibpointless2]

I had plans to do a EV motorcycle but I work at a Seadoo dealership and seeing this inspires me to do the same. I already have a 48 volt Etek motor. Is your motor connected directly to the driveshaft or that a pulley? What hull is that, looks like a 2 stroke GTX hull? Also have you had it in the water? Whats the speed and range?

Very cool, do you have anymore videos or pictures of your EV seadoo?

[zmatt]

Very cool would love to see some videos of it in action. How much did the setup run you and how much time did it take?

Keep us updated!
