Re: Islander 36 electric inboard? diy

Not to be a downer.. but I think this idea will come to a screeching stop when the costs start to tally up in comparison to a diesel http://www.mastervolt.com/marine/

Re: Islander 36 electric inboard? diy

that is a top of the line australian I beleive direct drive hybrid system...that has about as much in common with a forklift motor or similar system as a swan to a macregor...

my issue has been so far determining what off the shelf components can I use to install in my boat. a golf cart system would be nice and dandy for me.

used even better!

Re: Islander 36 electric inboard? diy

Christian,

Electric drives are very doable, but a 10kw motor isn't likely to be big enough. A 35' boat is going to need a lot more HP than this in anything other than dead calm days, when going sailing seems pretty pointless. Figure you will need a 25hp minimum, and ideally 40.

Re: Islander 36 electric inboard? diy

the palmer p60 a great engine btw with one big drawback(exhaust manifold) is 22hp at the crank...10 or barely more at the prop, 2 blade...

stock...

I wish not to make this a motorsailor...I was trying to ask specific questions, hopefully from that member who did so on his islander 36...he did so using forklift motors or similar...

I have no need or want a 40hp diesel...I found my 2gm yanmar to be plenty enough power and TROUBLE on my old h28 that only wieghed a ton less or so than my current boat...

The issue I have is that the forums seem to have a lot of unfinished threads...leaving more questions than answers sometimes...

anybody done an install in a remote location...using a weird combo of motor and controller etc..?

thanks

Re: Islander 36 electric inboard? diy

there are some commercial solutions, like
Products | GreenStar Marine

Their largest engine has been used on boats up to 40 ft.

Major drawback of electrical engines is the difficulty and limitation of energy storage. This leads to a limited range, and to a somewhat lower power compared to diesels. In itself this is not any show stopper as long as one is aware of it - you state you only wnat to use the engine when mooring etc - should work fine then.

Re: Islander 36 electric inboard? diy

the motor is only one part of a complex system of very large cables. (talking 400 amps and more) power source, batteries alone would sink the boat, unless you could source the new type, how to recharge (generator) , a controller. and more.

I realize this is an outboard but Myth busters Jamie is spot on what your talking about.
