My 1990 115 ETLN has been recently rebuilt. The prop put on was a 21 pitch and I am told I should have a 17" or 19" pitch instead. When planing the boat, I was also told to trim the motor higher up, on my trim guage, that registers at the halfway mark.<br />Anyways, when the motor gets up to 4000RPM, it starts to shake a little, and then the rpm's start dropping back to around 3000 all the while acting like it is choking. Put it back in nuetral and I am good to go up to 4000rpm again.<br />Is there a governor? on these motors? Am I trimming it too high? I have heard there is a safety device built-in to keep these motors from revving too high. Any ideas?
