I had some major work done, not on the engines but they were pulled. A few things replaced while out of the boat,
Spark plugs
New fuel filters on the block and in the carb
New fuel pumps
A few hoses
New fuel lines
When the boat got splashed the starboard wouldn't start. We checked for spark and fuel, both were present. The mechanic that was checking thought it might be the engine harness. Prior to pulling the harness he grabbed a jumper box, applied power to the coil, it fired right up. He pulled the harness apart and found the primary plug had some corrosion present. He did nothing but sprayed some die electric grease and it fired right up. He mentioned he didn't care for the style of plug used on the Crusader of this vintage. Said that there are better choices now, less prone to corrosion and poor contact.
So a few minor spins around the harbor since this issue and yesterday I am heading a few hours away - we were only about a mile out, I have been keeping a close eye on all the engine specs, oil, volts, fuel, etc all well within spec.
Not pushing the motors, just enjoying the time out on the waters. Cruising about 1300 RPMs and the starboard motor dies. Like I turned off the key....I immediately thought of the main engine harness and pulled it, used sand paper, cleaned off the contacts and used some more grease (what I had on hand)....Nothing. The engine fires but will not continue to run. I am wondering, could it be the coil causing this problem?? The harness at this point has been cleaned and the prongs re installed but I still have nothing. Thoughts?
