On my Hunter 306 the blower is rather loud. The offending noise is the hum, which might be the vibration of the little motor at the attachment, or, I wonder, if it is something out of spec for the blower itself. It seems to function perfectly well, just a bit loud. Has anyone encountered or dealt with this? Has anyone used a rheostat (and what kind) to tune the thing down? Any special retrofit installation ideas? thanks

What blower?
Mike: What blower are you refering to? Does your boat have a bilge blower? You may want to mount the blower on some rubber feet. The other option is to mount a board on some rubber feet and then mount your blower on this board with or without some rubber feet. Quite often a motor that is mounted directly on a bulkhead will set up an osillation that can raise a racket.

Blower
Mike, Our 290 (same boat) has the engine compartment blower. I have not noticed it to be particularly loud, but then, I seldom run it either. Seemed a curiousity that Hunter installs one in these boats. I presume that when you do run it, it is for a few minutes prior to starting the engine. Come to think of it, I've never even traced the blower duct to see where it actually goes. I suspect into one of the stern storage compartments as I do not recall an exit vent on the boat. If you think it is too noisy, you might try working through Steve's suggestions. The other alternative is try to find another 290/306 and see how it compares. Dan Jonas (S/V Feije II)

Blower????
I find it bizarre that your 306 has a blower. It uses the same 18 hp diesel that my 326 has, and there is really no need for a blower, which is a necessity for gasoline engines, such as the old atomic 4. My 326 did not come with a blower, but I do admit the panel has a breaker labeled for one.

blower
at one of the recent boat shows, i also questioned why you would have a blower with a diesel. the response was to get rid of the heat that was generated by the engine.

I think the blower is a good idea!
I run the blower after motoring to take motor smells out and cool the inside. The exhaust vent is at the stern of the boat near fuel filler.

not noisy
My blower in engine compartment is not very loud when I do use it which is seldom I forget to shut it off ,but check the mounting screws maybe they are loose and causing a vibration I have 290.

I've been thinking blower to
My buddy put one in and it helped get the smell out and also kept the heat down, it's a good idea.

it may be just charter boats,, but both...
the 2001 Beneteau 331 & 2000 Beneteau 381 boat we chartered in the BVI's had blowers that ran anytime the engine was operating. I thought it was a good idea since there is so much battery charging at anchor to keep the refer running. Not one whiff of diesel fumes inside the boat during both trips. Both engines had over 2,000 hours on them and everytime we left the boat, we closed it up due to chance of rain. etc.

Noise = problem. Fixed mine
1. you have a blower - that's a good thing and you should be able to use it without having to talk over it. Its simply a turbine fan, but a heavy duty one moving at hi RPM, so its going to humm a bit more than your bedroom fan. 2. you should hear a mild humm only. anything else and there's a problem that can lead to other problems if not fixed 3. test: first, torque the 4 mounting screws to make sure they are tight. then, turn it on and if the noise persists, reach up and grab the plastic blower casing in several places, firmly, in an effort dampen any vibration, if that's even the source of the noise. if this doesn't help, or else just changes the noise slightly, then your mounts are probably fine and you have another problem. 4. most likely cause: the turbine is rubbing where it ought not to causing un-necessary friction which could eventually cause the blower motor to fail from overstress. fix: remove the blower, disassemble the turbine housing, and inspect for areas of unusual wear. There are plastic parts in there that will eventually melt from the friction and gum up, dry once turned off again, and lock up the turbine should you try to turn it on again next boat trip. Use washers of correct size to offset the turbine from the casing so it spin free and clear. Clean up/sand any lumped plastic so that it doesn't make things worse. This is not fun as the blower is in a tight spot, but its certainly do able for the everyday do it yourselfer. have fun! brian
