When starting back up on pad, a loud, steady alarm sounded. I immediately backed off the throttle and the alarm stopped as I sat there idling for a few seconds. I very slowly returned to the ramp with no additional alarms. Does anyone know what a steady alarm from this particular motor indicates (I'm thinking either oil delivery problem or over heating)? Also, can anyone recommend a really good Mercury mechanic near Longview? The one I usually use is on vacation for several weeks. Thanks PB. 10 lb 12 oz

While I was at it I replaced both t-stats as the original stats were somewhat corroded. Both are easy DIY items. 2003 EFI 150 Last edited by Muzzlebrake; 10/13/17 12:57 PM.
