We have to look 4 ways to save money. If U look up kubota engines and go to farm.construction etc. instead of marine U will be surprised at what U can find. Like 20 inch by 20 inch by 15 inch 2 cylinder diesel 15 hp, 140 pounds.Yes we would have to adapt some cooling and
exhaust systems but I'm sure we could figure that out. They have 4 example an engine $ 2700 9.5 hp diesel electric start 3600 max rpm air and oil cooled. NO WATER
PUMPS,THRU HULLS ETC. We could use it 4 main motor or drive a couple of 90 - 130 amp
alternators and have lots of battery charging power and by
inverter 120 also. Lots of possibilities we just have to think about what we could do with all this information and equipment that is readily available . We could save alot of money and we are all cheap b----s anyway , right.
