Blower or no blower?

For me ALWAYS without exception. Gas or diesel. Blower switch is an inch away from key switch. Turn em on and leave them on. If mains or gen set is running, blowers are running. Cheap insurance and more so for piece of mind. If the noise of blowers bothers you then the stereo may need to be replaced. LOL

Yeah it does mine are pretty noisy mind you they are original to the boat so really they should be replaced along with the factory am FM CD Sony that can only be controlled from the cabin, the big block in my 268 crowns out all peripheral noise above 3k rpm anyways
 
Blowers on as soon as I am onboard, off when I leave. Genny is usually running. No scenario where I need to think about the blowers. Keep it simple.
 
As long as its ignition protected and blows enough air than you can get something alot cheaper than the Jabsco units. I used these Shurflo Yellowtails on my old boat to replace my failed Jabsco blowers. They lasted 4+ years before i sold the boat and are probably still purring. Nice and quiet, 3 yr warranty and cheap. At this price ($25 for 4") it makes no sense not to run them whenever you are out. Granted i would shut them off when on plane when i remembered, otherwise they were always running.

My issue on my new to me 320 is how loud they are....so I am looking for a quiet model.
I didn't have a loud one on my last SR 290. So it does take away from the peaceful easy feelin when your putting along and have a blower making a roar. I am at the age where I am not as concerned about the cost, but want a product that is quiet.
 
Aside from the blower just being a "loud" blower, there are other possibilities... the blower could have something stuck in it... a blade could be broken... also check how/where it's mounted. It could be that it's simply mounted on a spot that is reverberating and echoing the noise. Changing the mounting system could be all that you need. For example, mounting it like many fresh water pumps are done could help (mounted to a hose, with the hose then securing it in place).
 
Always!
Not only for the safety. It is part of a mental check list that I have done way back with my first boat at 14 years of age. I have diesels now and I still run the blower before start up and in July/ Aug I run it while underway to move the heat around in the engine room.

Look at it this way. You as the captain of your boat should be training yourself, anyone and all that come aboard that there is a safe process to boating and that starts with a good routine. If you dont run it what will your kids or wife do when they use the boat or if you have smaller boat to go along with your bigger boat.
Not only you but all people that boat with you should know your " check list" and live by it.
 
The Jabsco squirrel cage blowers referenced above are so quiet you can hardly tell they are running. Plus they are rated for continuous use unlike the inline blowers. You will have to change the breaker out to a larger size as they draw 11 amps each.
 
Gas boat, I run before start up and until on plane. Diesel boat, maybe to help cool down prior to/after docking if I want to go in the bilge to do something. As for moving heat around...I've got a couple tons of iron in the bilge, once up to temp that's were it stays, hot days/cooler days/blower on/blower off makes no difference.

Routines are good for sure. One of my most important is frequent bilge inspections. I'm in there after every run, it's part of preparation for the next one.
 
It is not a bad blower, it is almost as loud as any other I have used...it just seems like a cheap and noisy fan.
 
Have seen a boat blow up about thirty feet from me and two others at the fuel dock, fortunately no one was killed only injured. One boat had kids on it but our fuel dock had a set rule that all people were to be off the boat except the captain when fueling and restarting which saved alot of people from getting hurt or killed. I also run the blowers during startup and open the hatches and do a smell test.
 
Hi Guys,
Question / conversation... I have a 2000 340 DA Sundancer. Twin 454 MAG MPI Horizons.
Before anyone goes on about blowers, yes i understand how they work and you can run 100% duty with them. (with the correct ones). I have modified the air intakes on my engines so they breath better and the Filter / flame arrester can be removed in 60 sec to clean when needed.
Im interested in peoples thoughts on engine bay "Air in" and "Air out". I have owned her for 4 years now, and have noticed a clear difference between long running with bay door down, and bay door up about 4 inches. The 340Da (well mine) has the side air intakes, but when i climb in over the engines at the stern, there doesn't seem to be anywhere for the hot air to escape. If the only inlet/outlet is on the sides, then when you up and going wouldn't that create a pressure inside the engine bay with only moving air that the motors draw in? Which is now hot air. Always seems to run nicer with bay door up slightly, with air turning over. Has anyone modified the stern area and installed some air vents or the like, so air enters in at sides and air is then forced out through an outlet/s at rear??
Or if anyone can tell me that there is outlets that i don't know about.
Thanks for your input.
 
So Blowers are the Answer?? And just leave em on....While running all the time??
