Weiand 177 Spark Arrest Air Filter
 

Hello all - making progress on assembling of all parts for low boost blower project but .... I have metal spark arrestors on my carbed 454s. The weiand manual says you have to keep inside of those blowers clean and have some sort of paper filter K&N or something beyond the usual coast guard approved metal mesh ones.

What are you folks using?

Thanks!

Factory Merc 525SC flame Arrestors were wire mesh. They are 100% fine. You are not going to get any debris/dust on the water like you would get on land.

unless you are on dirt roads like us and keep boat on trailer. :)

they dont have dirt roads in florida,only sand,lol.

you boys obviously have not seen the inside of my engine room - even though she stays on the water, dust from neighboring construction projects seems to get everywhere.

Thanks for the answers! Didnt know what was on the SC.

Cheers

They are nice. If you have room, they have some real slick ones on Velocity stacks.

I also live on a dirt road and need to run an air filter. I'd post of picture of mine, but apparently I am not allowed to do they yet.

you have to be very careful on your choice, I did a setup like this few years ago, had a eddie marine HP arrester, 1st run would not make any boost 0 !! called weiand, said remove arrester 1st and run it..boom 6psi.
