Good question Frank, didn’t think of that. He says in place of…not sure if or how that would effect performance. If I have a chance to mount it on one of my motors and try it out before the end of the season I’ll post back.
Ok, so curiosity got to me. I installed the plate on my ’55 Johnson 10 horse, and took it out yesterday. This wasn’t an extensive hours long test. Just an initial test to see if this plate would have any immediate negative effect on the way the motor ran. I would have to say it did not. Maybe if I ran it longer, or tested on a bigger motor there might be, I don’t know. I looked at the top plug before and after and it looked to be burning about the same, maybe only slightly wetter?.
