Hi,
I have just purchased a 1999 Sundance 340 with twin 7.4 litre MPI Mercruisers and V-Drives. The boat is in amazing condition and I am ecstatic with it in all except one way. The enginrs run beautifully, oil pressure, temp everything; however after about 15 - 20 minutes running the port engine alarms, one beep about every 3 seconds, everything seems perfect, temp, oil pressure everything. Now this alarm only sounds if the engine is running above about 3000 rpm, if I keep it at 2500 or below it will run all day with no alarm.
When the alarm does sound, if you turn the engine off, restart it and keep it at 2500 rpm or less it runs beautifully.
Any thoughts?
I even wondered about an overheat alarm for the gear boxes, but it doesn't seem to make sense that it dissapears when turned off, restarted and kept below 2500 rpm.
Oh, also, when the alarm does sound there is absolutely no perceptable change in performance what so ever.
Any help would be much appreciated.
Regards,
Jon
