It would be cool to have an ev boat if you could generate electricity with the water somehow with some sort of water generators like a dam does

"B" is for "boy did you step in it when you bought this boat". Anything but a rebuild on existing engines would be complete insanity. 750k price tag new and it brings 42k in the sale used? Roughly 5% of the new price.....You'd see me running the other way, fast. Did he even do a survey on the boat pre-purchase?

Rebuild for sure. They will be less problematic in the long run. Seen multiple diesels with 40,000+ hrs on them with not a lot of issues other than common things such as injectors and obviously fluid changes and little things. Like you said they are made to keep a constant rpm while delivering peak torque/hp.

are you all crazy ? Go TESLA POWER ! and put 4 battery packs in there
Brent Nelson
Brent Nelson 14 days ago
Did the math and the Tesla packs will get you over 90 minutes of power at 25mph. Easily. And there is no reason that you couldn’t put 4 packs in that boat. The weight would be fine.

That's a lot of power for that boat. Semi truck run same engine pulling 80,000 lbs. You have 2 semi engines.

On the Electric range - you're considering ICE engines and electric motors as the same efficiency. "Conventional gasoline vehicles only convert about 17%-21% of the energy stored in gasoline to power at the wheels. An electric motor typically is between 85% and 90% efficient." That's why they use MPGe as a measure.

If you are budgeting stick to the engines you have. You will have known reliability. If you swap for anything else you will be spending a lot of time troubleshooting and modifications. The ocean in not a place to experiment.

Dude, stick with your diesels, have them rebuilt. Those are excellent engines.

Most diesels have an auto shut-off if oil pressure is low. I would install that and new gauges.

The problem when converting to a totally different power system is you would have to replace the transmissions also, that diesel is designed to run about 2100 to maybe 2300 rpm max. Gas is totally different. Fuel economy is vastly better with diesel, plus safety issues are critical, ie. gas vapor explosion is not uncommon in boats. Stick with the diesels
Caroline Douthwaite
Ev conversion sounds best, but you need a kick ass generator and double or triple the battery storage.

And displacements along time if you really look at gasoline got a look at the annual maintenance about every 3 to 4 years ago to replace exhaust manifolds risers all of that into the least 1500 to $2000 per engine each time he exchangers they go bad about every 10 years there anywhere from 1215 $100 appease a diesel has a whole lot less maintenance you clean everything you change the oil the exhaust riser you take in your boiled out you may have to reach a change it periodically every 5 to 10 years and there a lot less money Ono a diesel is less expensive to maintain and Yuri seo value is exponentially more

Depending on fuel efficiency and fuel prices you may be better off staying with the diesel engines repair of rebuild they are at least reliable when in good running order and the boat was designed for them in the first place and safer as far as fire safety is concerned since diesel has a higher flash point than gasoline and the change over to gas entails more modifications than you may think.not just the tank and fuel lines but other electrical additions as well as fire suppression system you may want to include .for safety you know ..just in case because a fire on a boat in the water and/or in the middle of nowhere is no joke..the other equipement that needs replacement or upgrading are just as important. I live in Fl. and boating is one of the number one things here and boating safety is a legal thing all over the world. navagation lights are juust the tip of the proverbial Ice Berg. thyat boet is "{a big hole in the water that you throw money into never to get it back,,,,GOOD LUCK!!

Ok so why replace 2 diesel "truck" engines with 2 electric/petrol "car" motors? 2 Electric bus motors and and 400kwh storage would be ideal. The Tesla semi truck would be an ideal donor for range and speed.

Cummins engines are the dogs danglies. I think you've been a bit unlucky if you've popped the head gasket. Just have it rebuilt, get it back in the water and thrash it! If you wanna tinker, get rid of that horrible red hull!!

Hauling that much gasoline on you boat turns that tank storage into a bomb if there was a leak. Stay Diesel. You have the Diesel motors already, and that keeps your classic boat a “classic.”. They are essentially maintenance free. I had a 453 Naturally aspirated Detroit Diesel in a 69 Ford truck. We carried 170 gallons of Diesel fuel. I inherited it when my Dad died. What a beast! if you have “off-road” Diesel powered equipment in your shop, you can get Diesel without road tax, it would be pretty cheap. I used to get 55 gallon drums filled, and fueled my “equipment” from the Drums. I also used Chevron 30Wt Delo oil for my oil changes, which I bought in five gallon cans. You must do your oil changes regularly, as well as a fuel filter and a water fuel filter as well as an oil filter for those frequent oil changes. Again, I vote and recommend keeping it Diesel.

I know this late but putting gas engines in that boat will reduce the resale value to almost nothing. I suggest you call Seaboard Marine in Oxnard, CA. They are experts on marine repowering and they can answer any questions you have, especially performance issues and prop sizing. Cummins has a number of reman enigines you might consider.

Put in electric engines along with the batteries. Then on top of that, put in Generators that can run on diesel that can run the engines at 80% load when you need to go fast. Best of both worlds. Cheap range when you want to go slow, Not so cheap range when you want to go fast. Also, with diesel this setup, your range should be about the same as with nothing but diesel engines.

Stay with diesel it is actually more efficient for boats, it has more power, you have longer range, and those engines will go forever as long as you have fuel. Seen a Riva with das engines and yeah it had speed but it went through 300 gals in less than 15 hours, the vessel I was on we had 200 gals and went from long Beach ca, down Ensenada and back to san deigo the gas engines are also more flammable than the diesel, you would need to put blowers in the engine compartment to clear the fumes out.

The ICE age is over. It’s been way over for diesel and way way over for gas, for awhile now. Many folks are converting worn out cabin cruisers to electric, but I have not heard of anyone crazy enough to try it on a planing hull. Good luck.

Been boating a long time including at one time owning a propeller shop. My take on your situation would be to buy either new Cummins motors or Mann motors, lighter, more torque. Advantage much less maintenance than gas, and much more dependable.

that " backfire" you mentioned was probably a crankcase explosion caused by oil mist ignited by bearings runing red hot, The excess crankcase pressure created was relieved by blowing the rocker cover gasket and the oil fill cap

I once or twice went on a (sailing) yacht on auto-steer out of Nice, France, eastwards. The trip had all the excitement and interest of being on one of those kids rides at the fair with old style cars on a track. Way to make your life boring (a truly cruel fate for a Riva), which is "Born to Run". And I get you are not doing that. Your boat - your game. Should be fun. If they were designed to be diesel stick with it (I would - you wouldn't), then by all means upgrade the electrics and controls. Automate the hell out of it, but remain in control. Recondition your engines now and you have fun for a lifetime, and if Riva isn't Italian for fun, I don't know what is. Have fun, I'll be enjoying it too.

The Tesla electric power system would be better for a smaller boat that was for fun and weighed less, as far as that goes the Texas speed engine or rebuilding the diesels better and badder I think is the best bet, more reliable and stronger! Plus you already own them just build them bullet proof and badass

We run a D4 in our boat. Single engine boat. Gota go deisel man. 39knotts 55 ltrs per hour at our comfortable cruising speed around 23-25 knots 35-40 ltrs per hour. If you can get hold of a pair of KAD44 be great or a pair of AD40’s. Reconditioned be the way forward. The AD models are basically tractor engines. No complicated engine diagnostics. Love the videos.

your best way and all the way round and what i would do is remove both Engines and have them both rebuilt then put then back in your boat diesel is way better then a gas Engines for that size of boat you have. diesel Engines will last a lot longer then gas and diesel is cheaper to run . so what ever you do say with a diesel Engines .

DO NOT put a car engine in it. It will get FRIED FAST. Those engines run full power for a long time. Try driving your LS for 2 hours down the highway near redline. It will blow fast. Second, the car engines don't make enough torque to get that boat out of the hole, because the cam needs to be changed and a whole ton of other things. Leaving the car engine core plugs and steel head gaskets in salt water will kill them pretty fast, also the cam needs to be an anti reversion cam, regular car cams will pull water from the exhaust and hydrolock the engine in a blink of an eye. Also aluminum car engines don't last very long in a corrosive marine environment. Would also need a swap of all ignition parts, need a different fuel and timing map. that cummins may not make a lot of hp, but the torque is huge, which is what you need to get that boat out of the hole. In my opinion the best would be switching to the newer QSB series engines.
