Bob,....I just bought a 1994 Merc 150 EFi (The 184 Champion attached to it was free!!..)
and had it checked out by my mechanic buddy up here in MI. He checked the cylinder pressure (110psi in all 6), checked the EFI system (AOK),..cleaned and examined all engine filters (AOK) and did the lower unit pressure check...AOK. He told me that I should get 2 new voltage regulators because the one's on there are still the original ones (clear resin over the circuit boards) and they're eventually going to catch on fire!! :blink: He pointed out on one of them where it was already turning the resin a "tea colored brown" from heat. He said I need to change them to the black resin one's. He also told me to get them on-line, since they're much cheaper that way vs. paying dealer prices. He will install them for me once I have them. Should I stick with Mercury parts or is there a common and GOOD aftermarket brand that will work,..and what is a fair price for 2 voltage regulators for this motor? (BTW,...my mechanic said this motor has been extremely well cared for and he hasn't seen one that age, that looked that good, in a LOOONG time.) I still have not started the motor yet,..the weather has been really chitty and I hope to get out this week. I'm assuming that since the motor is already 17 years old, I can run it for awhile longer with the original reg's still in it....correct?? I want to get them changed ASAP,..but I'm assuming it's not mission critical before I use it this spring,..correct??
Thanks for the advice,..really glad you're back!!

I would still replace them...just because, when you get a chance.
