"My 1992 ski nautique with the pcm 351 pro boss engine started pinning the needle with 80+ high oil pressure.
There are no other indications that anything is wrong - engine temperature, sounds, etc.
However, the limp mode has kicked in and it won't go above 2500 rpm.
I suspect a problem with the sending unit, gauge, etc.
What engine troubleshooting might I do before I just assume it is the guage and something significantly wrong in the engine?
