If you run a genny, the genny would be louder than a fan "unless you have a eu honda".

 

I think this will depend on your setup. What hp engine and how much pitch you have. They can get loud at wot but nothing compared to an airboat. When I am slowly cruising along my fan noise is hardly noticeable. In fact I was stopped on Guntersville lake last year by the DNR for a random check. The DNR did a decibel test. When I started it up he said my fan was quieter than most bass boats at idle. They only check you at idle speed, at least thats what I was told. After I added a belt reduction and increased the pitch my fan became even quieter.

 

Do they check the decibel level at idle? I've always been curious about how they go about that. That would be cool if they do because my fuel pump makes about 3 times more noise than my fan does at idle lol.

 

If on throttle it make more noise then genny, else the genny make more noise.
My genny had honda motor in it.
My 2 cent plus tax make 5!!

 

Mud, I'm glad i don't pay taxes were you are from. lol

 

A boy around here has one and I can hear his fan over my airboat if we are fishing on the same flat

 

i heard that thing! it was rediculous loud

 

yeah fans are nice and quiet until you touch that throttle haha. still not horrible though IMO, Noise wouldn't stop me from building one

 

Id rather have the noise/speed of a fan than slow/quietness of trowling motor....

 

X's 2 !!!

 

Big kicker...

 

Make an airboat or push fan then? Cause for what a 35 hp
Honda cost I can build a nice fan setup with a vortex v6

 

Alot of fan noise comes from fan shroud design. Keep the sides open.

 

A three blade prop, will cut down on noise. You can improve on the muffler if you try. Safe to say the only fish that I know of, that are noise shy, are silvers.

:hb:

 

So what size motor do ya'll suggest for a 1654 modifiedv

 

13 hp, with a 40 inch, 3 blade prop was working right out of the box, for me. I feel sorry though, for the folk who have to push against current. That requires horses.

 

K thanks

 

I usEd a 16 hp 36 prop and did great on my 1652 when I had it.

 

Any fan = noise
Just the nature of the beast....but the pros far outweigh the cons!
