I just purchased a 1985 Supra Sun Sport. It has a Ford 351
Boat starts up runs and idles perfect. Once I get it out on the water everything seems perfect I shut the boat down to relax go to fire it back up and get nothing, no click, no turn over just dead. The gauges jump up when the key is turned. Battery in good shape, new starter and new coil.
Once the boat sits for a short while it will start back up.
In driveway it starts up all the time. However I have had a few time where I had to jiggle the ignition lock rod?
I should mention if not already figured out I know nothing about boats.
Thanks for any advice
