My 1981 Hydrasports originally came with a 235 Johnson Sea Horse. I pulled that and put on my old Rude 140. Can anyone tell me whether the tach pulse off the Rude would be different from that of the Sea Horse in terms of readings? I'm showing 5000 RPMS on the Rude at WOT, but not much speed (of course, I'm also aware that the 'not much speed' might be due to a simple lack of horsepower). I'm running a line straight off the rectifier/wiring connector to the original tach that came with the boat because the signal is not making it through the wiring harness to the tach for some reason.
