I have twin 2002 225 optimaxs on my boat one compressor went . I cleaned out all the lines because the oil in the lines from the compressor were silver from the metal and I replaced the two In line filters . Now I need to prime the new pump before I start it . I tired the key on and shift to nuetral and then foward 5-10 times and then the oil pump should run for 2 minutes to prime the system how ever it’s not working . I then tried it on the other motor again the oil pump did not run . I read on a lot of forums this is how you do it . Any ideas on why the key on nuetral to forward is not working ?
