Have a 2000 Baja 342 Boss
twin Mercury 7.4 Mag MPI
At all speeds, the boat runs fantastic
When I shut the boat down or any length of time, the starboard motor will not start ?
It may start an hour later it may start a day later
I already changed the cap, rotor and distributor ignition module.
I have a new distributor pick up sensor, but I’m avoiding putting that in because I would have to pull the distributor
At this point, I’m not sure if it’s ignition or fuel at this point
Kind of thinking a vapor lock issue but just not sure
any assistance would be greatly appreciated
