We trailered the boat (99 VP 5.0GL) across state for long weekend getaway and the have electrical or starter issues. Arrived and it started it up and drove off trailer and into slip, ran perfect. Tied it up in a slip and let a afternoon rain shower past ~2 hrs. Went down, started it up and ran fine for about 30 seconds, was starting to untie dock lines and missed terribly, almost knocked like it dieseled and stalled. Would not crank, not even think about it. Checked voltage at starter and it was OK, terminals were suspect so cleaned the large battery feed. I then got scared it hydro-locked, but I can turn it using alternator, it has crank mounted sea water pump so no real good way to turn motor by hand. So I think the knock/stall was as it ran out of voltage to the coil and ignition was quitting? Is that possible? I have checked/cleaned every connection I can think of and still nothing. I have good 12V at the starter battery feed and if I jump 12V to the solenoid side still nothing....acts like a bad starter. No click, no hum nothing. But boat stalled..... Downside is outside starter bolt is WAY frozen. Previous owner didn't do great job with taking care of boat and has been salt water most of it's life. I have been soaking it with penetration oil and even heated it slightly with LP torch but not sure hot hot i can go so didn't really kill it.
