225 hp is 168 kw. Lead acid batteries produce about 20 wh per pound. LiPo maybe half the weight and 5x the price. 3 hours x 168 kw = 500 kwh. That would take 25,000 lbs lead acid batteries costing about $75,000.
Does no one do the math anymore?

I've looked all over the internet over the past week for family IO open bow type conversion to electric but have not found any. I own a 19.5' Crownline, deep V, 3500 lb. boat w/ 4.3 V6 225 HP. I would like to remove the engine, gas tank etc. and replace with simular performing electric drive system connected to the Alpha 1 outdrive. Any one out there done this? What system will give me performance, ability to ski plus about 3-5 hours cruising at a reasonable install cost? I know this is a broad question with tight parameters. I'm hoping to learn from other's experience and knowledge. I can spend $4k-$8k. Help please.
