Re: Electric Drive: Who uses it?

I hate to say it, but waiting for the range of diesel, in a battery, is probably going to take longer than either of our life spans. Even if someone figured out the battery, it would take some...

Re: Electric Drive: Who uses it?

Taxes are less than a dollar per gallon in every state, and less than 75 cents in all but one state. Unless you have found diesel for...

Re: Electric Drive: Who uses it?

4500 is the red line for the engine when it was used in cars, really terrible cars. Anyone in them at the time they reached that rpm, were probably screaming in terror...while traveling well under...

Re: Electric Drive: Who uses it?

The engines are original, which is why they're dead at this point. 40 years of occasional use and what doesn't leak is seized. I can only assume they intended it to fight heavy currents and wind...

Re: Electric Drive: Who uses it?

The engines, Volvo Penta MD21A, were rated at 75 hp at 4500 rpm, 50 hp at 3000 rpm and reached peak torque at 95 ft.lbs at 2000 rpm. One motor was able to keep the boat at 6.5 knots at about 900 rpm...

Re: Electric Drive: Who uses it?

Fun little thread going on here. Since I'm about to convert my boat to electric tomorrow, it should be fun to see how it pans out in reality. It's not the usual use case though, seeing as I'll be...

Re: Where are all the newbie sailors?

As a newbie myself I have to say this site is a wealth of knowledge. Which is why I don't post very often. Usually a search turns up the answer, or at least leads me to where else I need to look.

Re: Keco Eco Cooler.

It's some kind of peltier cooler, and the site hides the full power draw of the unit. Most likely because it's less efficient than a typical compressor unit. Peltiers are nice for being silent, but...

Re: Marco Island to Marathon

Just made that run back at Thanksgiving. It's a bit of a haul, but not bad really. We started late afternoon so we would hit Marathon as the sun came up, turns out we went too fast and still went...

Re: Ft. Lauderdale Boat show?

Pompano Beach nautical flea market is in January just before the Miami show if you're in the area. Useless for boats, lots of small pieces parts. Worth it if you happen to be in the area anyway.

Re: Trying to source a dinghy lift

That might be it, I do see one similar lift on their site. Almost all of them are the hydraulic version though. Looks like I might have to get down to the boat show to ask them.

Re: Rational for a Hybrid?

A hybrid diesel only runs at the most efficient speed for the engine, regardless of what speed the throttle is set at. Given a battery bank large enough to move the boat at wake speed for long...

Re: 122volts from 4volts ac, after a small spark?

Without seeing it for myself there's no way to tell for sure what connection was made or broken where. However if an arc happened and then you could read voltage where you couldn't before, then...

Re: 122volts from 4volts ac, after a small spark?

It was probably a loose connection that was welded when the probe shorted it. Double check every connection. One of them is in a very dangerous state. If you're going to be leaving the boat, shut...

Trying to source a dinghy lift

I have been searching all over the place trying to figure out who makes this dinghy lift.

Re: Leaking PEX valve push fitting

If you're removing a fitting every year, stop doing that. Put in a T with a valve on one leg. Just because you can remove a pex fitting, doesn't mean you should. Liquid and gas fittings require...
