I have been having problems with one engine, it only starts when the engine compartment has had some heat, it has been narrowed down to a failure in the main module. Everytime you heat the module the engine starts with no issues, once cooled overnight same issue, engine won't start. A new module is just over $2k CAD, not really wanting to spend that type of money on the boat, was hoping someone had some suggestions where I can look for a used module?
