i am a marine service company in mexico wishing help in converting a 40 foot trimaran from diesel to electric propulsion.? ?Garth Jones.? ?I need some help and advice

The big difference in efficiency between the sailboat and the trawler is the turbulence and drag of the transom. I don’t know how much less efficient it is but it’s a lot of churning water. At

4-5 MPH is more realistic from a 7.6kW generator. Most motor and controller setups will require DC power input. A simple bridge rectifier may make that possible. For that large prop, you will need a

Capt Carter - what kind of motors do you have, and how do you control them? I agree with your statement about 4mph being more reasonably achievable - but that in wind and current, I would probably

John,? To give you a comparison, the Arc is 45' long, 13.5 wide, 3' draft, and weighs 20 tons. My electric motor will push it 1 mph at 500W, 2 mph at about 1000W, 3 mph at about 2000W, 4 mph at about

Agreed - if the diesel engines keep working, there is no reason to replace them.But what if one or both dies? The most expensive part of an electric installation is the batteries - especially for big

Your 7.6KW generator is equal to 10HP, but there is inefficiencies when converting from AC to DC too. There are a lot of variables, so there is no easy answer to what you would get, but I would guess

The following scenario is a "what ifffff" for a "trawler" class cruising boat. These boats are generally powered by old diesel engines - typically 120-275HP each (twin engines). If the diesel engines

Thanks Jeff, McMasters sent me his videos, says he can maintain tow speeds for about 45 minutes. The tech has improved so much since I started following this, and continues to, I hope greater battery

My rule of thumb is 1 amp per lb of thrust at 12v... so 80 lb thrust at 24v would be about 40 amp. wrote:

Hello all, I first got on this thread when I had a possible project - a 2000 Bayliner Capri, with Force engine. (lost in forest fire) I assumed I could use the lower end of the drive (replace the

i was going to use a later 60 hp chrysler lower unit bigger prop no tru prop ex parts from early force same .lots of them around and cheap. ________________________________ Sent: February 2, 2020 9:50

Keith M, My next install is amp. meters. So no data yet. The prop was printed with PETG, if I'm remembering correctly. Glenn -----------------------------------------From: "Keith M" To:

Trolling motor heating is related to current draw, which is related to load. For a well-designed motor, if you operate it below its maximum rated current, you should't have any heating problems.If you

Glenn - Awesome, do you have any data on the current vs. speed.? What material was used to print the prop?

Ken - Any suggestions on drilling the shaft hole for the prop?? I used my drill press yesterday to drill my 15x7 Master Screw prop.? I let the prop self-center on a surface square to the drill bit,

Günter - I second the quiet time on the water.? My family has a very nice fishing boat with a 250HP outboard, minimum planing speed is 21 MPH and you cannot hear yourself think.? I have owned
