Re: Islander 36 electric inboard? diy

Christian,

I wasn't aware that you had a gas engine already (I made my money on the hull and rigging, not engines ). I think Greenstar was pretty reasonable about his proposal, though I am a little hesitant about his battery usage profile. It isn't that I am opposed to swapping to electric, just that most people don't have reasonable expectations about what electric can provide.

Further I have questions about how they can make the assumption that a 5.8kw continuious engine has the same rated output as a 18hp diesel. HP (or KW) is the same no matter what the source.

Finally, adding a generator... It is certainly doable, but using a gass generator is going to be somewhat cumbersome. Most marine generators are diesel, and the couple of portable generators (like the Honda 2000) that are gass, really are not suitable for permanent installation. I have seen it done, but still question the real risk of fire and explosions from this type of installation.

Frankly it comes down to what you are trying to achieve. If as you mentioned before you need a few hours of run time each way then I highly doubt it as a suitable option. If you are ok with just a few minutes then it is certainly workable.

Re: Islander 36 electric inboard? diy

Christian under 6 kilowatt isn't good for you.
An Atomic is a lot of work. You would be working, to change 4 quarters for a dollar.
Pull the Palmer and try to fix it at home, even run it on a test bed. Little parts can be mailed to you.
Usually 9.9 hp outboards can be 15 hp with only a larger jet in the carb.
In the meantime:
Your 8 hp may do better with a 3 bladed prop, centered on the transom, lower, and maybe a larger jet.
I see why outboards are taking over the inboard market.

if so this guy sells and uses a 2.2kw motor kit, PLUG AND PLAY this is something Im trying to emulate...

again auxiliary power...not motorsailer
That was the boat Teal. I think he spent 2K for the conversion including a couple of batteries & small solar panel. The system is not plug & play but there was a parts list in the article. There's no link to the article I know of but
I'd be happy to scan it for you if you'd like. Send me an email.

Google , ''electric sailboat Teal '', and the article is in PDF.
His motor is AC I believe, direct drive, low RPM, and 48 vdc.
Today for the same price, you can get a higher hp.

Re: Islander 36 electric inboard? diy

thanks guys, so it was the same boat...I loved the article because it related to my needs, his boat was only 1500lbs or so lighter than my boat, but I have a longer waterline which is a benefit...he also emphasized on it been auxiliary power in terms of HP. which is a great point we seem to ignore...

bernard motissier for example sailed around the world twice on an 8hp or so 1 banger inboard, just to help anchor and whatnot...his boat was 39 feet and displaced over 20k lbs...!!!

unfortunately the palmer has been recycled and discarded...the big problem with them is the exhaust manifold...once they crack and die you cant get a replacement or fix it for cheap...I already had sourced the copper gasket kit and all other parts needed for the rebuild...$2000 or so...

I found on ebay some very nice solas props for sailboats, high thrust 3 and 4 blade...for most common outboards...if I do go that route this will be a MUST.

thanks sony
