I am looking for a pair of 15x32 3 blade cleavers to test on my boat. Don't mind paying or giving a cc. Just don't want to buy a pair til I know they are right for the new engines. thx.

Call brett at BBlades, I think they still have a test program. small rental fee or something like that.

Yup still does.

Go with 4 blades you will be much happier.

Thx

Why?

Less Vibration, carries the extra weight of the xs's better. I also have the 250xs's and I have found that stock 15X30 mercury 4 blades run really well or if you want to spend the extra money a set of labbed 15x32s with the 4 adendums cut off and pitched to 31s work really well. I had a set a both and the labbed one were my favorite for top end. The 3 blades might get you an extra 1 or 2 mph but the 4 blades are better everywhere esle.

Will the four blades also help your lowers last a little while longer?

Yep sure do!
