conversion 8 hp outboard powered by 5 kw generator
orfish
Newbee so dont forget we laugh together right? Ok my idea for my 34 foot chb is to gut the 8hp gas outboard motor stuff in a 1/4 hp electric. Then power the new electric outboard wiit with a 5 kw northern lights generator. Would this work? Thoughts very welcome. Im wondering that I should start with a bigger motor like a 25 to 50 hp because of the bigger prop .. I only am looking for 3 mph for trolling for salmon. ok Ive got broad shoulders and can take the abuse or am I on the right track . heres hoping

I consider myself a newbee to electric propulsion having only powered my sea kayak with a minkota and a 12volt agm battery. The guys on this forum are very helpful and very patient with newbee type questions. I would have been way more rude to the newbees who want to power their 250 hp waterski boats and dont even take the time to read up on how impractical that would be. What would be helpfull is more info from you and your particular needs. What does your boat weigh? Where are you going to be using it?(river, tide currents,ocean, lake, windy,etc) Is the 8 hp motor the only motor on the boat or is it just for trolling? My own take is-- If this is going to be the only propulsion on your boat you will need way more than 1/4 hp electric motor and you need batteries. The main reason to add a gen to the set up is range extension/safety factor. You won't care about the gen making noise if you get caught out in bad weather against a tide or current with batteries low. Going with a no battery set up is harder/more expensive than just buying a good efficient 4 stroke outboard. My statements are mostly based on what I have read here and elsewhere. I have done a small experiment with two 30 lb thrust minkotas on my 24 ft F-24 sailboat in strong wind. I could barely get it to roundup into the wind and it took forever to get to shore. If the wind had been stronger it wouldn't have worked at all. So I don't think any one is laughing. You just need to tweek you idea a little bit. I want to encourage you to keep asking questions and see it through.

I only want to use the electric power for fishing at less than 3 mph and occasionally against the tide of 1 mph
my boat is 34 feet 15 tons my preference would be 120 volts or 220 ac powered by a 6 kw gernerator ive heard that 2 kw = 1 hp and Id be close to maxing out .. all questions needing answers respectfully Orfish |
