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.

Did this happen last weekend (Labor Day weekend) and were you in salt water?
Might try pulling the spark plugs and see if you can turn the engine over by just bumping the starter to get the water out. Of course if it was salt water and sat there for a week, you need an engine. It's locked solid.

Re: Starter and/or electrical woes

It happened this weekend and was in fresh water . Since I can turn the engine (although it is a pain because of crank mounter sea water pump) . I don't think it is hydro-locked, but I can pull plugs to make sure. If motor was locked I would feel starter bendix and solenoid and the starter would "try" to start it. I get nothing. Any tips on frozen starter bolt? (starboard one)

Re: Starter and/or electrical woes

I don't know what your harness has for protection (fuses and breakers) but I'd be checking for continuity across them all. I don't see how the starter problem can be related to the shutdown unless they have the same common problem. One of my 50A breakers that is mounted on my starboard riser went bad and stranded me two years ago. It did not trip, just went bad internally and caused the same symptoms you have. I wired across it to get back and then replaced it.

Re: Starter and/or electrical woes

I soaked it this am. before work and tonight tried again..same deal..will not bulge. I am scared to heat it too much.......how hot is too hot is the 2 million dollar question. I have a Mapp Gas torch and although it is ac/ox torch it is quite a bit hotter than LP. It is getting nerve to heat the crap out of it..........any thoughts from those who might have heated that area before? Surely I can't be the 1st guy with a rusted starter bolt. I ma trying to be patient and allow the penetrating oil to work at it , I know I will be sad if the socket rounds.

Mike: Start a new thread about your starter bolt problem and you'll get a better reponse. Only thing I can say about it is, like Don said, make sure you use a 6-point socket. You're smart being patient as I have read many posts on this forum about broken starter bolts and/or engines having to be pulled to change them.
