I have been running Drew Marine's "SHOTGUN" exhaust silencers on my Baja 302 for about 1 1/2 years without any problem. Last week I went to service them (salt water you know) and found one of the springs seemed to be broken. I called Drew @ Drew Marine and he sent me out four (4) new springs that day at n/c. That is great service by a company that stands behind their product and supports their customers. By the way the spring was not broken, just stuck. Thanks Drew!!!

Be sure to lubricate that bushing that the butterfly shaft runs in. Drew told me that the shaft will bind which results in welds breaking.

Thanks Cord:

I got the same info from Drew. He indicated that they really need servicing on a regular basis when in salt water.
