Anyone ever try these reeds.

Had them on a 30 hp Suzuki, proformed well 

Unless you have a modified motor you're planning on turning a motor 7,000 rpm or more, I wouldn't mess with them.  The only difference you're going to notice is after a few months, they won't idle as well as the factory steel reeds.  They will not make anymore hp.  If you don't have adjustable idle screws, you will have to rejet the cabs idle.   The motor may feel a little better at idle and mid range when they are first installed but the idle get worse once the get flexed.   

I've tried them a couple of times in my hotrod motors and ended up doing away with them each time.  Since I only turn 6,500 - 6,800 rpm, I don't need them and they are more of a pain than they are worth.

I can't speak to their performance in your application, but we used them years ago in high performance two stroke motorcycles. In fact they were a "must have" easy mod. Their advantage was the opposite of Way2slow's experience. It was the stock metal reeds that would take a set and not close properly. We used them to increase low-mid power and throttle response since they opened easier and closed quicker.

What you will notice with Boyesen dual stage reeds is easy starting, smoother idling, quicker acceleration for faster holeshots, crisper mid-range & they carry RPMs further past peak allowing you to run a steeper pitched props.

In the shallow marshes (10-14" of water) of Southwest Louisiana you must have the ability to get on plane in 25' or less with an outboard of 40 horses or less. The only way to accomplish this is through fast hole-shots; Boyesen reeds, steep pitched props, jack up/setback plates and tunnel hulls allow this.

There is only one reed that i will run and that's CCR

Chris Carson Reeds there great reeds 210 286 5154 and there a good price Boyesen reeds are junk

Just went up today to their factory and bought a set for my 60/45 jet. I needed to replace mine and they are slightly less expensive than the factory ones. My originals were 15yrs old before showing wear. I know the fiber ones won't (most likely) last as long. I am heading up to the lake in the very early am tomorrow. I will let you know....

I was suffering from hard starts and loading bad when coming out of no wake zones. Originals were def. bad, you could see alot of light under them and .020" feeler would darn near fall through them.

I replaced my old motor on my 15' Grumman bass boat  with a 2003 Mercury 25 hp that came with a nice stainless prop . I live on the Delmarva Peninsula (Chesapeake Bay) and fish alot of shallow rivers and ponds. I already put a CMC PL35 trim unit on that works well to help perfomance and was just looking to see if anything else could help. Thanks for the input guys
