what is the point in that converting a 9.9hp perfectly good engine into a shitty 2hp eletric outbord i dont see the point your best of getting a electric motor readybuilt you have just waisted a good engine

Put your mind at ease, the 9.9 hp gas Yamaha was rescued from going to the dump. As is tipical with gas motors used in the ocean, it had siezed up. Having been converted to electric almost 4 years ago now, it has run perfectly and has had no need for gas or oil. I have also converted a junked Honda 9.9 to 10 hp DC electric with similar good results. Today there are lots of newer & better systems available out there, look around and see what is available and coming.

thats no posible i mean 6 hrs on a 50ah car batt thats a 500 watt engine if it isnt more

[48jimd2]

If you would like to go with me for a ride and see for yourself you are more than welcom to come along. The batteries are at least 100 to 150 amp hr and the motor is 2 hp but I run at about 0.8 hp as that brings the boat to max speed due to the pitch of the prop. If you want to see a fast electric boat take a look at the electric hydroplane that does about 100 miles per hr. Now that is realy something to see.

motorfordtoyota@ i think max 10 min hahahah

[48jimd2]

I resently ran a test to answer your question using my 20 ft boat and found that one set of batteries with no extra power supplied from the solar pannels lasted 6 hrs. This is some what longer than 10 min, By the way, this is the second year I have been running this old set of used batteries I picked up for $30/ea.

I see a lot of comments from people that have evidently never been on a boat and know nothing about the engineering and power calculations that went into this.

I am an EE and I own a sailboat. What you present here looks perfectly plausible. Thanks for the presentation, and if I had the need, I would buy one.

@soverato3 My geuss is 1500 watts

[mumbleye]

@48jimd2 good work making the world a better place. dont listen to the jackholes that question what you do. oil is death, electricity is the future

[mhansl]

Nice job. After seeing an all electric airplane a couple years ago I realized that the future of transportation is in electric power. A few more years of battery tech innovation and we will start seeing real changes.

That thing is Screamin'!

[maximumoverdrive96]

i'm pretty sure thats a trolling motor

[joel53]

Wooww..its great Bro..., what electric motoro do u use ? how many watt total solar panel in that boat ?

[MrTpengineer]

@jordyboy0129 That "shitty" 2hp has about twice the tourque than the 9.9 gasser :) That and depending on the batteries may have longer range.

[joracer1]

ok fellas i see you're using on a sail boat, but what about a 200hp bass boat, what wt

would be needed to haul up up the lake at 50mph for maybe 3hrs, is this feasible?

their is a glooming problem with the gas we're using now it has ethanol in it..

that's bad gas, electric might work even if you have to slow down a bit........

i'd use an old fork lift controller and a dc motor, i'd be alot cheaper.....
