Hey Bill,

I am currently installing the Thunderstruck 12KW Liquid Cooled 48v.

Be ready to waste most of your time cleaning out all those hoses and and who knows what else.
I have taken the opportunity to upgrade everything inside. It is a good opportunity to do things right. 

Taking universal 25xp engine out soon. Engine is in working order. Only taking out because the admiral doesn't want diesel on the boat. Going electric.
Located in the long island sound  Manhasset Bay.
also have other engine parts that no longer will be needed.


Diesel tank also will be removed.
PM me a price

Thank you carbon.

I was thinking of starting with the liquid weight the numerous tanks theoretically have at capacity.
On my c34 we have the two water tanks. The diesel tank and the blackwater tank.

Plan:
Removing diesel tank.25 gal.(at capacity is 175 pounds)
Removing the waste tank. 30 gal.(250 pounds at capacity)
I can remove one of the water tanks.

My first inclination is to place the 48 bank where the waste water tank is.

For the 48v bank We are looking at 308lb.

I will also replace the old 12v bank and add 2 12vlifepo4,could be 130 pounds.

I am looking for a favorable place to have the large battery bank.

The dimensions are 38"Long X 15"Wide x 10 height.

what do you guys think would be the best place?. all tanks on the boat are going to be replaced so i have many options. Keep in mind, i wont have a gas tank.

Carbon, the motor is not really meant to be run at 100%.
If I want to achieve 4 knots, the 20kw bank should give me several hours of quiet motoring or i can turn on a generator and help the bank along. A 5kw pulsar generator would be able to supply the 30amp to the battery charger and also allow me to run air conditioning, with no issues.
Below is some data of a 32 foot Pearson with the same motor I purchased. I think with electric propulsion, you have to design it for the purpose you intend to use. All I want is to be able to go around long island.
If I was cruising down to the caribeans, then I would add a kubota generator and run a hybrid system.

Might want to check with your insurance company. They may require a survey to determine if the installation meets ABYC standards before you get down the path of no return.

good idea.

You are right about the limited range,
That is why solar and a small generator will need to be added as a backup. A small inverter generator in a purpose built enclosure would give us plenty of energy to motor out of the cove and keep motoring for hours at a decent speed. I was thinking of it being some sort of hybrid system. The new inverter generators are very quiet and very easy to maintain, they are cheap compare to diesel generators. They are also very efficient, a honda 2000 with .95 gallons at full load will run for 3.4 hours.

I actually did some intensive research over the winter and settled on a 48v system. I will be adding a 48v to 12v converter for a 12v battery. The main battery is a 20kw lifepo4 48v 400ah bank.
One of my main question is placement of the battery I don't believe our battery area currently by the sink can fit four 8d size batteries.
The range will be tested and if not sufficient we would add a generator in some sort of enclosure. Current gas/propane generators are very quiet and have clean power at very high wattages (30amps).
I will for sure document the steps and will be hoping for critique and better ideas if you all see me doing something wrong.

Robert— Why did your wife "mandate you remove the diesel"?

we are on the long island sound, so there is some periods of no or very little wind. We endup motorsailing a significant amount. Unfortunately conversations and diesels don't mix. She likes to talk. I tried dampening the noise. But it was not significant enough. So her car is electric and now her boat will be as well.

Over the winter the admiral mandated that I remove the diesel.
The 25xp will be removed soon.
I have purchased the thunderstruck 12kw kits. Anybody have any experience with electric propulsion on a Catalina 34?

Are the lewmar ports size 0on a 88 C34? I have a few i have to change as well. Do we have a list of all ports sizes?

So looked at some bags my wife cleared from the boat and found a Orberdorfer pump and some old alternator. Looks like these were original and then upgraded to the n202m-16. Mystery solved.

Are these old pumps worth salvaging? Can I just purchase a cover with o ring.

[202M pump]

When took the cover off this pump had the O ring on the body not the cover.

Based on the year of the boat (unless she was repowered or the pump replaced) it is a 202M pump not an N202M pump

The number on the body does not match the casting for an N202M pump, but back then (before the company was sold 3 times) Ob had a casting number not part number on the body.   Current N202M pumps carry the part number and date code on the body.

Make sure it is a GENUINE Oberdorfer kit and includes the cover gasket (not o-ring.)

Inspect the shaft for scoring or wear at the location of the lip seals, and the fit of the shaft in the carbon bearing before you order the parts you need.

Note that there is a cover available if you want to mod an old 202M pump to use an o-ring rather than the paper gasket.

Thank you.
Found a repair kit on ebay for 89bucks. Not too bad.
