I liked that marina we spent a month there before heading to the Great Lakes, it is much nicer now the restaurant is open.
Greetings,
Mr. 4712. Is that a wing on your port stabilizer? What's the story on that?
The one pic looks like a 10 or 12 inch automotive cooling fan. How much $$$ was that. I have 8 of them in my engine room. 4 in and 4 out, all temp controlled. Total cost, about $350.
Excellent. More air moving thru the engine room never hurts. I have an off/on/auto switch for mine, each has its own switch and relay. The bank of 16 relays are controlled by a thermostat when in auto mode. The relay bank is fused at 150 amps and each fan has a 25 amp breaker and two 30 amp relays with indicators. Fans pull about 9 amps each. Same setup as my bilge pumps except they are zone controlled with time delays.
On diesels, all you really need is good ER ventilation, the giant air pump that is your engine will suck in all the air it needs. "Blow in" blowers and fans are nice when you are working in the ER, or if for various design reasons the vents are small. Interesting to note, Hatteras installed DC "suck out" blowers in the ER, primarily to vacate battery fumes (duct inlet is near the floor) and advised using them when below planing speed. They also installed additional AC "suck out" blowers, with duct inlet above the engines, both to help cool off shut down engines and to evacuate the compartment if the fire system had discharged.
