    Default Starter short..

    Hi guys, i had a battery melt down, my bildge pump stopped working and was taking in water. My fly wheel was slinging water into the starter and motor died, i pulled the motor hatch and a tone of smoke came out. While looking around found that the posts on the battery had melted off. My question is can the starter short out and cause this to happen??

    Please help..

    Thanks

    A shorted starter is usually obvious, it will crank slowly and run the battery down and people will address the problem at that time.
    A + battery cable shorted to will usually melt the insulation or the boat.
    Issues at the battery post tend to be bad connections that generate the heat necessary to melt the lead in the connections.

    You don't sound like you have spent much time on mechanical things, i would think the cause of the problem should be rather obvious. Battery is junk already junk, might try installing a new one, repair/replace any wires that are damaged and when you connect the second cable to the battery and it makes big sparks find out why.
    Has anybody worked on the starter recently? A starter that won't disengage could cause overheated cables/connections if the engine did not start...should be notice that easily...maybe + battery cable shorted against exhaust?

    Why does the boat have enough water in it to get the flywheel wet in the first place? not that is necessarily a bad thing in this situation, water on a battery cable shorted to ground might be the difference burning to the waterline or sinking under it.

    Thanks for reply, i have a issue with the oil pan being to big, the pan was hitting on the bolds for the intake of the pump and drove them out the bottom from what i found out. I recently rebuild the motor myself and didnt see the pan hitting, everything bolted up. The pan is a ten quart, so now i have to replace it obviously or dent it in. Yes im very mechanicaly incline, just never had this situation before, going to pull the starter today and test it. Always having starter problem, never ends! Because the hot lead goes directly to the starter is why i think with all the water entering the starter is why i think the short is from the starter the starter is brand new.

    What do you think?
    Thanks

    I have had to grind a few of those bolts down to clear the pan..one of those things you pay extra attention to after you have to fix one.
    Most of the water issues with starters take a long time to happen...Starter motor will work under water...its the corrosion from water that causes problems and it's not something the would melt parts..i drilled 2 1/4" holes in the bottom of mine...thinking water in has a way out..engine heat should cook and moisture left...don't know yet if it will work...my starter does see a lot of water..under it from water over the bow and high pressure car wash....

    You might want to give everything a good visual inspection before you get to wrenching...main cable to solenoid routing....the end bolted to the solenoid might have rotated...the case insulator where the bolt/strap comes out of the solenoid to power the starter motor might be missing/torn...cranking the starter is a dead short to ground if that happens....everything else in the boat should be...needs to be protected with either a fuse or a circuit breaker...
    Nothing more scary than a 14 gauge wire running through a wire harness with a dead short to ground on one end..the smoke is toxic as hell not to mention what flames can do..my deal has minimal electrical. A single 20 amp circuit breaker covers everything...It happens to have come off old HD low ridder...has built in tabs where it bolts to the rear fender....

    As for starter problems..some people never do and some people always do...I have tried 3 different flex plates...2 of them were the good ones...4 different starters including a gear reduction 2 with straight bolt pattern and the iron nose angle bolt pattern i have now...none of them ran deep enough in the gear..ended up angle milling (with a grinder) the mount surface almost 3/16"
    and made a rear support for the motor to hold it in place..Nope..no idea why

    Water came in from missing pump bolts, correct? Unless you sunk the starter last year and it has set the entire time with water in it it should not be a problem..and it if did it would just work like crap or not at all.
