I'm needing some guidance. I just recently purchased my first boat. It's a 2007 Centurion Typhoon C4 with the PCM Excalibur 330 and the PCM vdrive and transmission. I have a dash light that I believe is for the vdrive. It will randomly light up. It's at different RPMs. Sometimes I will be cruising at 3200rpm and it will be off then on then off again. Where is the pressure sensor located? I've tried the upload the pics but having some trouble with the sizing and I can't seem to link it either. Thanks for any help.
