Morgans with Atomic 4
We have a 1972 35' classic sloop Morgan with an Atomic 4...raw water cooled, pretty much original, have only replaced alternator...she runs great, very reliable and pushes her along at 6.5 at 2000 rpm's. Not envious of any one.

1970 Morgan 33
Own a 1970 Morgan 33 w/ Atomic 4 we purchased in 1975. Original Atomic 30hp engine just installed new carburetor and new Vetus exhaust system in 2005 ( article in current issue of BoatUS DIY magazine ). Built a removable cockpit dining table for my tiller steered Morgan, featured in SAIL back in 2004 and soon to featured in BoatUS DIY magazine.
Sailed the New England coast for thirty years now permanently down on the Chesapeake Bay. Just completed the installation in the forepeak of my Morgan a 5000 btu 110v ac air conditioner. This installation will be featured in the first issue of BoatUS DIY magazine in 2009. Last edited by gary gerber; 06-17-2008 at 08:42 AM. Reason: added new info |

Morgan's with Atomic 4
Gald to see all these Morgans with the original motors.
I have been rebuilding a 69 Morgan 34. Just got the motor running after almost 4 years on the hard. Replaced Carberator, Exhaust, Fuel Pump, High Output Alternator, Fuel Filter, rewired the entire motor thanks to all the kits/parts/advice from Don. Added Air, Spark, Fuel, and away she went. Had a bit of trouble with the reversing gear, the motor didn't want to run in reverse, every time I tried it would stall...I had to use a bit of elbow greese and the starter motor to get it running in reverse. Now I need to consider Fresh Water Cooling, I'm still cooling with raw water which I'm sure is not a great idea. Can't wait to see you A/C installiation. I want to do that but was going to put it in the hanging locker so I can vent to the V Berth and the salon at he same time. Dave |

New Morgan Owner
Hi folks,
I have a Morgan 1969, 33 I purchased last year and it came with Atomic4. Serial number 200923. I have been having problems getting the back two cylinders to fire. Have changed the plugs and have checked compression. I am thinking of fuel pump and possibly ignition/timing. I am getting spark but seems to be low. The fuel pump looks like it was an after thought by the way it was installed. It is an electric pump but does not seem to be installed correctly or maybe not the right one. What kind of fuel pump do you have on your Atomic4? Also I want to put a PERTRONIX IGNITOR II on the motor to see if that helps. Has anyone used one of these? |

The popular electric fuel pump is the Facet Gold-Flo cylindrical pump as offered in the MMI catalog. I have one and it's been a rock solid performer.
The added features of the Ignitor II™ electronic ignition compared to the Ignitor™ (the usual A-4 EI) is lost on us due to our low RPM. If you decide on an Ignitor II™ system be sure to read the instructions carefully, particularly any advisement about maximum amperage. I don't know if it's any different than the Ignitor™ but look for it. It's really important. Really. Also if replacing the coil, I recommend an oil filled rather than epoxy filled for better heat tolerance and as close to 4.3Ω internal resistance as possible. You'll find the Pertronix Flamethrower coils max out @ 3Ω spec, usually measure 10% greater, 3.3Ω. This will have an impact on system amperage and likely require the addition of a ballast resistor.

Make sure you don't have the #3 and #4 plug wires swapped. It's easy to do.
