They are a wholesaler but will do cash sales if over $50 - easy if you're buying much. They are all across Canada.

Actually it won't make the other live except when the pump is activated by the float switch. And it will only be live to the switch which stops the current flow in the manual direction as the manual side is off. The Rule and Blue Seas bilge pump switches are really SPDT switches like the one below -...

The bonding at the through is not needed with Marelon through hulls - would have no effect in any case. Remove it.

mitiempo

Bonded nylon (probably Marelon) through hulls?

mitiempo

I would run new wires. On a 28' boat the runs aren't long so 14/2 would be fine for the lighting runs. To make it easier re the lighting ahead of the main cabin you could run 14/2 or 12/2 to terminal blocks and from there to the loads. Terminal blocks from Blue Seas or similar are very inexpensive. ...

mitiempo

It is practical but would need custom fabrication. A tank of the size you can fit in a material that will not corrode - stainless or even fiberglass - a coil inside and connections for engine cooling in/out and water feed in/out are all that is needed, of course with insulation surrounding it. If yo...

mitiempo

I agree. Bonding made sense in the past when shorepower and marinas were rare. In present times bonding the through hulls is an invitation for corrosion of an item that wasn't at risk before. Here's a link to the best treatise I have come across relating to bonding.grounding by Stan Honey and reprin...

With the bar through the mast firmly attached to the spreaders and therefore taking all the compression load there should be almost no loading on the plates.

The Sea Dog panels are ok. The run to them can be fused and they can be linked with an appropriate size wire as they will be very close I would guess, probably within inches. This is the same way the buses are connected on a large Blue Seas panel, usually with 4 or 6 awg wire, I forget which. That m...

mitiempo

Hi Not sure how many amps the starter uses, but 4 awg will handle 75 amps with 3% voltage drop over a 14' run. If it is a bit large it will only lead to easier starts. 4 awg will handle 160 amps outside an engine spaces - 135 amps inside engine spaces. Fusing - either ANL or MRBF - 120 amps is a goo...

mitiempo

ABYC has an exception for fusing starting circuits because a powerboat with large diesels cannot be easily fused if at all depending on engine size. But any diesel up to 75 hp and any outboard likely to be found on a sailboat certainly can. I routinely fuse starting circuits and there has never been...

mitiempo

The cones on Hayn Hi Mods are re-usable, unlike some others.

Don't forget to allow for the stretch which all new wire has.

Interesting reading here. .http://www.briontoss.com/education/arch ... csep99.htm

mitiempo

Make sure you fuse the bank close to the positive post - ABYC calls for within 7".

mitiempo

Non-momentary bilge pump switches have on many occasions been forgotten and burned pumps out, leading to possible fires. Say if you turn it on and leave the boat for some reason. The price is the same. Best to do it the right way. I would never wire a customer's pump in such a way that it could be l...

mitiempo

Looks fine to me but make sure the manual SPST switch is momentary so it can't be left on.

mitiempo

I wouldn't bother with a start battery if your outboard is easy to pull-start. The main reason for a separate start battery is that whatever happens to the house bank you will have a charged battery for engine starting. In the case of an inboard engine that can't be started by hand I think it is a g...

mitiempo

Looks great.

mitiempo

Doug Looks like a very well thought out system. At a quick look I see nothing wrong with it. You oversized some wires in my opinion but other than their expense that is fine. Normal AC wiring is 14 awg which will more than carry the max output of the breaker (15 amps) The 10 awg you have used for it...

mitiempo

Bob

I think it is a DC main switch. The AC panel above it (360 series from Blue Seas) has the double breaker 30 amp main AC breaker at the top.

Never rely on any GFCI off the boat for safety. In a circuit of outlets the first should be a GFCI. It will protect the others downstream.

mitiempo

A barrier coat can help if the hull is dry enough to apply it. Interprotect 2000 is the most popular choice. 5 coats are recommended and there is a very limited time after the last coat before bottom paint. The last coat should be still tacky when the first coat of bottom paint is applied, or the ri...

mitiempo

Exide makes a good battery. Their GC-2 is comparable to the Trojan T-105. They seem to last as long for less money according to what I have heard. Based on the specs I found on the GC-5 it seems comparable - 65 lbs and 226 AH.

mitiempo

The shallower the container the better off you are. I mix and use in old margerine containers about 2 1/2" deep and 6" across - I always save them for epoxy. I use the West pumps so the measurements aren't necessary and it is easy and fast to mix in small amounts this way.

mitiempo

Looks good.

Are you using fast or slow hardener? I always use the slow hardener for that extra bit of time.

mitiempo

In Providence I doubt you will get 10 hours of full solar charging. I would figure on 5 to 7 hours at full output.

mitiempo

I think the answer to getting the first coat of bottom paint on while the last coat of Interprotect is still tacky is to have 2 people, one applying bottom paint as the surface of the Interprotect gets tacky. I don't think one can accomplish this.

mitiempo

There are many ways to wire battery a switch or switches. I don't think there is a need for 2 though. And there is nothing wrong with a 1/2/both/off switch. But the charging output from the alternator (or any other charge source) should not go through the switch. The best way to wire charging output...

I seldom if ever wrote letters - I phoned.:) Most of my online time is spent on another forum (Sailnet) that makes it easy with their colorful options. I have written more on forums in the last 2 or 3 years than in the previous 40 years!

mitiempo

Oh, those gallons, the little ones. Up here a gallon weighs 10 lbs.

Why are there no smiley faces to use on this forum?

mitiempo

True, weight higher up will increase the roll period but at a loss of stability. If you put 500 lbs 2 feet above the waterline as in this case (it may be higher) you have a vertical moment of 1000 lbs (500 x 2). To maintain the vertical center of gravity you need 1000 lbs 1 foot below the waterline ...

mitiempo

You say "under the side deck". 52 gallons (close to 500 lbs) high up is a mistake I think. Low down is the only good place for a water tank.
A separate fill is a better choice to segregate the supply. If one leaks you will still have the other.

mitiempo

Here's where:

mitiempo

That sounds logical to me, and the charging arrangement with 2 engines makes sense as well. Does the charging from the Xantrex Truecharge go direct to each bank? They are good chargers and I have installed several lately. Are the negative connections from each bank to the main ground point, either a...

mitiempo

A large battery bank is more efficient than 2 smaller banks. The bank is not taken to as low a state of charge as 2 separate banks so the batteries last longer and charging is easier to manage or automate, Here`s a full explanation: http://www.sailnet.com/forums/gear-maintenance-articles/19797-batte...

mitiempo

All good questions, but the charger should float at 13.5 volts. 14.5 is bulk/absorption voltage for flooded batteries.

All 4 golf cart batteries are best used in one large bank without the ability to separate them.

mitiempo

What kind of lighting do you have that is both AC and DC?

mitiempo

Can you explain exactly how everything is wired and how it is charged. A picture might help if you have one.
I too have never had an issue with golf cart batteries, whether Trojan or other brands.

mitiempo

I tape the hole underneath. Then mix epoxy, fill hole, and let sit a few minutes. Using syringe, remove epoxy and mix with silica to thicken. Fill hole from the top with thickened epoxy and tape over quickly.

mitiempo

Cabosil is colloidal silica. West # 406.

mitiempo

You will regret it if you buy too small, not if you buy too large. Anderson is my choice. More durable than Lewmar or Harken. These are 28's and 40's. The boat had the 28's as primaries and the cabintop winches were old Lewmars and not self tailing, mismatched, and one pawl was broken. I already own...

mitiempo

Strange - if the third connection was jumpered to the second they would both have been positive outputs.

mitiempo

ABI still exists but they are no longer in any part of the marine business.

mitiempo

Doug Is the negative post of your batteries connected at one point? I just looked at the manual and can't see where else you could have gone wrong as long as the #2 and #3 positives are jumpered. As far as the reverse polarity, it has to be the dock as the reverse polarity indicator is wired between...

Wouldn't bronze suit the boat better?

mitiempo

Could be a bad battery from the beginning as you suggest. This is certainly not representative of golf cart batteries I have installed. How much load was on them when they dropped to 10.5 in less than an hour? I would try just 2 in series leaving the low voltage one and one other out of the mix for ...

mitiempo

I misunderstood - just watched the video.

I carry a 4 part tackle with ratchet block and ascender, have 2 chairs but will get a climbing harness. I can get to the top easily. The ATN does let you get past the top for easier working up there though.

mitiempo

What's on board already? Not if you are alone.

mitiempo

I agree. A conventional stuffing box is predictable, a few drips when the engine is running or an increasing number of drips. A dripless is either perfect or a bit of a disaster.

mitiempo

The lubrication of a thin layer of water is not great. When the shaft is spinning at 1000 or 1500 rpm it needs all it can get.

This link may help. Some of these stern tubes are designed to direct water flow into the cutlass.

mitiempo

I agree, a slight inward angle will look better. Longer spreaders will lessen the load on the rig, possibly at the expense of windward ability due the the wider sheeting angles, but the trade off can make sense for some.
