Has anyone tried the msd knock sensor on a boat motor?

here is a link http://www.msdignition.com/tool_8.htm

having detonated a fresh engine with probably bad gas I was considering this.

the msd when i looked at them wasnot set up for marine . i ended up getting some from Anson ,i got them thru gaffrig marine..did same thing with a melt down from a restricted fuel line fitting.. good luck

Got one in boat. Problem is you can not hear it between the exhaust noise & the wind noise. There is an adjustment for sensivity but I have never felt is was right. When I cruise at 3K the gauge is going wild saying detonation. When I am WOT it does not show detonation. When I am running hard it is hard to look at it. Has it saved me from tearing up a motor? Nope!

I run them on both engines with gauges and idiot lights. I had to try several different senders before I found a set that would not go off above 5700 rpm. This was before I found out that the torque on them is important.

I had one go off at 4000 rpm when a lifter quit working.

rbtnt,

are you running the msd? if so do they have an external trigger for a pro-light. I found the unit that Livorsi sells (anson?) $600+. A little out of my budget. The MSD unit is about $170.00.

thanks guys.
