I hope I get this correct. First I am very dislexic so please bear with me a bit.
I have had many boats, and have loved a few thousand open ocean miles single handing. Mostly on sailboats but have had a 48 foot uniflight, and a 42 foot Giles. I have just picked up a 50 foot steel boat, waterline is reported at 45.8 feet, beam is 15' 8". She was built in 1964 as a pilot boat an used in Alaska. She has an original single gray marine 6-71 natural. The wheel is around 36" with a 3" shaft. She holds over 3,000 gallons of fuel
My question here is I am thinking of re powering her. I was thinking a 5.9 cummins would be to small at 210 hp. Maybe a 8.3 cummins. Or I might have an option of obtaining a big cam 4 cummins just rebuilt for around 10k, no transmission. It is just a truck engine. I would keel cool, and dry stack?
I think the 5.9 cummins would stall when you engage? Also I need a hydraulic clutch pump to run bow thruster, and there is a large hydraulic windless for and aft, and a hydraulic crane on the deck.
This is a lot, any help would be great. Realy not sure we're I am going.
Thank you
Obie
