Perkins 4.154-200
Been sitting on a mooring field in S fl so I'm pretty sure the root cause is a heavily fouled prop.
Temp alarm was replaced 2 years ago so it should be fine.
We went out and motored fairly hard for about 4 hours. When we were coming back in, the whole drive train started vibrating. No vibration in neutral. Tried reverse several times, thinking we picked up something. Didnt seem to help. Dropped anchor for about an hour to attend to something else. Started up and all seemed fine. But 15 minutes later the alarm goes off. Slowed way down and went below. Heat gun checks found nothing extreme. That is what I am most perplexed about.
We went to the mooring and shiftin into reverse I start hearing nasty crunching sounds! No noise in forward. I suspect its barnacles that found their way into my max prop.
So most of this is likely from a very crusty prop.
The only mystery is why the engine alarm when nothing seemed hot by multi heat gun readings.
