My Universal M35B (a newer engine based on a Kubota diesel) calls for 20 seconds of preheat if below -5C (23F), 15 seconds if -5C to +5C (41F), and 10 seconds if above +5C. Press start while holding preheat. Continue to hold preheat after engine starts until oil pressure reaches 15PSI. Do not crank engine for more than 30 seconds.
Here are the procedures for the M4-30 from the operator's Manual: 6. Place throttle lever at 1/3 open position. 7. Turn key to "ON" position to energize fuel pump, glow plug and oil pressure light. If your panel uses a key switch start, go tOh)9. 8. Press "Glow Plug" button for 30 to 60 seconds, depending on the outside temperature. Continue to hold glow plug button while pressing "Start" button to crank engine. Release both buttons immediately after engine starts. Go to 11. NOTE: YOU MUST HOLD GLOW PLUG BUTTON IN TO ENERGIZE THE STARTER BUTTON FOR CRANKING ENGINE. PANELS WITH KEY SWITCH START 9. Activate "Glow Plug" switch for 30 seconds to 1 minute, depending on the outside air temperature. It may be necessary to hold the glow plugs on during the time the engine is cranked in very cold outside temperatures. 10. Turn key to full "right" position to crank engine. Release key immediately after start. MAKE SURE THE KEY RETURNS TO THE "ON" POSITION. NOTE: When cranking engine, only crank engine for 10 seconds and pause for 10 seconds. Repeat until engine starts. (See Caution printed on Starter Motor.) You can download a PDF copy of the manual at http://www.westerbeke.com/OnlineManuals/200157_M12-M50_Operator_Man.pdf . You said your engine will not crank with preheat button depressed. That does not seem right. Suggest you look at the troubleshooting pages from the Universal M4-30 Technical Manual at http://www.westerbeke.com/OnlineManuals/200155_Rev2_M12-M35_Technical_Man.pd f . Rick Brass Washington, NC From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of David Knecht Sent: Wednesday, May 15, 2013 3:52 PM To: CnC CnC discussion list Subject: Stus-List Starting a Universal I have only had a few tries at starting the M430 engine on my new boat, and I have been told several different stories. One person said to hold the glow plug button for 5-10 seconds and then start. Another said 30 seconds on the glow plug and then leave the button pushed while also pushing the starter. The latter worked when I was first starting the engine after the winter while plugged into shore power. Yesterday I started it for the first time without shore power and found that the starter did not kick at all if I started while also holding the glow plug button. Started find when I let go the glow plug button. What is the "normal" starting procedure with a cold engine in cool weather. Warm weather? Warm engine?
