Hey Guys

Any input would be appreciated.

Late last year my boat started to develop a really "weird" intermittent problem. when the boat was "cold" after sitting overnite or for an entire day. I would get in, turn the key and NOTHING would happen, no solenoids clicking, no change in volt gauge, it was like the key switch wasn't even hooked up?

Sometimes I would turn the key 2 or 3 times and other times it would be 6 or 7 and then "bam" the boat would fire right up. I figured it was a loose connection, ground, bad solenoid, the "usual suspects"

Here is the weird part: Once the boat has "started" once, it fires up on the first try for the rest of the day/nite. I was out one day last year and had to turn the key probably 1/2 a dozen times before it started at the dock, naturally I was a little nervous about going out in the river and not being able to restart the boat to get home, so, I turned the key and it fired up instantly, I went for a 30 minute run, shut the boat off, turned the key, and once again it fired right up. we anchored and swam for a few hours, decided to come home, and AGAIN the boat fired right up. I got back to the dock that nite, and when I came down the next day to go out again I had to turn the key 3 or 4 times before it would start?

I have had this happen in numerous race/classic cars, but, it normally happens when the starter gets HOT, not when its Cold?

I am thinking of changing the "key switch" and see if that helps, since all the other connections "seem" ok

Any input?

Slave solenoid x2.

Where would slave solenoid be? On the starter or remote? Boat is a 1996 Baja, single 454EFI B1 drive,

Anyway to test it? Would a "regular" automotive solenoid work? What would cause it to only act up when it was cold?

Thanks
Michael

Nutral safty switch? Try holding the key over to start it and wiggle your shifter.

exactly the same problem on my 496 it was the slave selenoid.

Does any of the accesories work before you hit the starter? Is so I agree slave solenoid.
If not I had that fuse block go bad. Long shot but check it if you still have it on.

It is at the rear of the engine, see 17 below. To be sure use a test light on the small terminals of the solenoid. If you turn the key and the light comes on and the solenoid doesn't click, you have a bad solenoid.

Thanks guys! I appreciate all the help, will try and diagnose it this week sometime, thanks again!

Great! Anyone have a part number?

I looked online and the ones I could find on Ebay looked just like regular automotive style remote solenoids, could I just use one of those? Or are the marine/Merc ones different?

Thanks!
