What ever charge source you have/get needs to match the charge profile of whatever LifePo4 you purchase. I was able to keep my xantrex inverter/charger because it had the digital panel to program to the tenths not just a position that said lithium, agm, etc. I was surprised at the difference in...

Got the quote for two Shaft Loks. It will be 4k shipped. About double from what I recall from a couple years ago. Another thing that could change my mind: I have a hydraulic pump on the starboard engine that runs the stabilizers. If I shut that engine down with the stabilizers in the center...

Darn good question. My alternator has no markings orher then 12v. It’s between 50-100 amps-still researching. Also looking into 24v alternators (if mine are only 50 amp) that can fit into the ridiculously small hole of the existing alternator. I have 2800w of solar to help top the house bank.

My model is MG 5061: 3 to 1 ratio

Victron Orion-Tr Smart DC-DC Charger. Bluetooth capable as well.

Copy. The oil conditioners will help, but I hate the stains they leave when it rains. I went to the other extreme and used Durabak on my teak decks on my old boat. You have to add sand on top or it's a skating rink. Lasted great for about three years and then it was a nightmare to remove when it...

TT: More great info! I have no room where my alternator is jammed into the engine. I was thinking about a 24 volt alternator to the house bank and dc2dc for start battery, but I don't think I could get a higher rated 24 volt alternator to make a difference based on efficiency of the chargers.

Are you brushing against the grain? Brushing with the grain (parallel) to the caulking will remove the teak quicker.

Thanks TT! I'm looking forward to adding the dc2dc chargers. The 12v alternator and 24 house bank has been driving me nuts (not being able to send any charge to the house bank while running). This site always comes through. Thanks ERTF for starting this thread!

Peter: True about intended usage-not a choice of mine. My engines are 210 hp each. I have a hunch that pushing 90 tons with one engine vs two engines will put that single engine in the intended usage range (going 5-7 knots).

I have a 24v 1200 amp. LifePo4 house bank. My start battery is 12v. I can't fit a larger alternator. I think my alternator is 100 amps. I have twins. I have no charge going to the house bank from my alternators now, so anything I can get is a improvement. I can parallel the dc2dc chargers (15...

I'll find out the expense, but I'll install myself. I smoked the turbo on my last boat cruising in these conditions-engine ran in the 160s F. Turbo never spun up fully. My engines are naturally aspirated, so not as big of an issue, but still worried about cylinders: From an article by Steve...

Thanks TT! Very helpful. Wasn't getting the fact that an alternator has a continuous rating. Wonder if the continuous rating is listed on alternator's, or if the distributor will tell you what it is? Also wasn't sure if the dc charger had heat sensing for the alternator (does not).

Cat 3208 naturals. Temps are perfect when I get up to 1800 rpm or around 8 knots. I end up going less then 7 knots due to traffic, waiting for bridges to open etc.

After dragging when I first started boating ( had my head shoved way way up my ass), I scuba dived on my set anchor in west sound Orcas Island. I was shocked at how many car sized rocks my rode was weaving through. Promptly purchased 320 feet of BBB.

So you limit the rating, but that doesn't account for running the alternator until the house bank is full (time). I burned up two alternators to figure this one out.

There have been many articles talking about how damaging underloading a diesel engine is. Specifically non electronic fuel injection engines-mine. There is a 7 knot speed limit in the ship canal. There is no opportunity to speed up to burn off the carbon. I have a triple keel at the stern-my...

As far as drag of fixed vs free wheeling prop is going to depend on the boat. A sailboat with a two blade prop that can lock it straight up and down behind the keel will of course have less drag. My 90 boat ton with full skegs in front of the props, will hardly notice weather the props are...

That was actually the motivation behind this invention-the noise of the free wheeling prop.

I'm not sure how the dc2dc charger works. Will it protect the alternator from overheating and frying? Standard alternators are only designed to charge the starting battery. In this setup a large house bank will continue to demand power from the start battery (and alternator).

Interesting. Designed for a sailboat, but in reality it would be much easier to engage with a powerboat.

My Krogen Manatee had several copper pipes that were attached to a water hose/line with no barb! Just a hose clamp holding it together. After 20 years, they all started to leak.

Does your chain locker drain over board? If not, a lot of rain runs down the chain/entrance to the chain locker if you don't have a cover over your windlass. Also, make sure your house pump is off when you leave the boat. So many hose clamps will get loose over time and start to drip. When I...

Are the boards teak? They make specific black caulk for the teak seams. Most marine stores carry it.

Spelled incorrectly: Should be Shaft Lok
