![]() For medium, to heavy-duty a water-cooled system is often necessary. What cooling system is included with the Bellmarine inboard packages?Įach inboard product is available in an air-cooled to water-cooled variant depending on the power requirement and duty cycle of the vessel. ![]() A variety of gear ratios are available to get the desired output speed. The Torquemaster introduces the use of a Drivemaster with a mechanical reduction. Is it possible to add a reduction gearbox into the driveline? The Modularmaster incorporates system redundancy in one package using two Drivemaster motors. Now you know why I said "significantly overpowered, as a 26ft "house boat" like this has no business operating at those speeds.More than one motor can be used for added system redundancy and greater power requirement. ![]() With the 185hp V6 Mercruiser, she tops out at 31kts mostly empty and 25.5kts loaded, and this is with a commercial kitchen, and all affiliated systems (full fuel/water tanks) because I have a huge amount of room in the stern of each outer hull, enough room for large enough electric motors to put this gal on plane, of course, that's not at all the plan/need. I want to steer with them, joystick controller, like a tracked vehicle, and B. The reason for two motors (port/starboart) is A. It is my intent to operate under strictly electric propulsion, and to eventually eliminate the V6 -since a boat like this only needs to hit 4-7kts, and will normally only travel about 10miles/day. This boat will be operating 12hrs day 6 days week starting early-mid December, so if I am to do this, I need to do it NOW, and I am asking for the advice and suggestions of anyone in the know who is willing to help in any way. It is presently powered (significantly overpowered) by a V6 Mercruiser.Īt this moment, I have a complete electric propulsion system based on a pair of 82lb thrust MOtorguide trolling motor lower units, Yandina Trollbridge24 and a bank of four 8D batteries charged by main gass guzzler or 5.5KW genset.īefore fabricating the brackets/trim/Kort Nozzles, I stopped to do some further research, -simply put, I'd rather stop right here, sell off what I was ABOUT to use, and put together a pair of 8-15kw motors/drive/controller (and probably beef up the battery bank, or perhaps switch to larger diesel genset for a sort of diesel electric setup. I have a 26ft JC Craft Tritoon which is converted into a Concession Boat (basically a food truck on the water) Me, I'd prefer a battery pack to a bigger generator.Ĭomments for Electric Boat Conversion With Generator You didn't say why you don't want to use batteries to run your motors, but I guess you've got a good reason. The trouble here is that if you don't have any storage batteries, you need a larger generator to provide enough power for acceleration. You need the most energy to take off, then less after you reach cruising speed. The boat is pretty much the same, I think. In a car, the size of the generator is really dependent on how much acceleration you need, because that's where you burn the energy. If you've got more than one big V8 engine powering your boat, you can figure on one big DC motor (A NetGain TransWarp 11 or 13?) with its own big (30-40kw? More?) generator to give you the same kind of power. ![]() I think you're asking a lot from a 10 KW generator. I'm going to have batteries for running lights, bilge pumps etc., but I want to run the motors with a generator only. boat's V8 gas-guzzlers to 2 DC electric motors that run with a 10KW generator.
