The 8.2's were pretty quiet. Mine were 250 HP versions. To say the Cummins engine is loud, is a new one on me. The 6BT is the 6-71 of the new millenium. Thousands of them in all kinds of service grinding it out day in day out without problems. The 8.2 never did anywhere close or it would have had a production run longer than a good lunch hour.

It's true that I didn't have proper soundproofing for my 6BT 300hp, standing over it in a pilothouse and all, so I guess i gassed myself. Too many of them running around in obnoxious over-squared pickups, tormenting me at traffic lights...

Methinks that 8.2's are reliable Detroits, like your cited 671, a WWII tank engine. They did have a cooling problem if an air pocket wasn't cleared, but in later versions you have a turbine-type 4 cycle howler Andy Granatelli would have liked.

racing rpms!!!

I am at my witt's end trying to figure out why the port engine (8.2l) will race if left at idle. the problem is that the throttle WONT shut it back down.. I have to shut the engine off. I have tightened up the throttle linkage and even tried my hand on the engine to slow it down. no luck.

This will do this in the start up if left to idle and as it slowly warms up it will begin to race to 2500 rpm.

Worse is when docking. Coming in, it will race as you are manurving to the dock. The stbd engine will not do this.

Anyone able to help here???

You could check out boatdiesel.com, pay 25 bucks for an annual fee, and get all the info regarding diesels in boats for many years in the past.
A very cheap source for information
