New Boat / Engine Break (shocked at go full throttle recommendation) ???

[DanielC]

The higher price only makes my point even more valid.

still playing devils advocate:

The most critical time in an engines life is the first time they are started, at the GM factory. The engine then goes to PCM, for converting to marine use, and probably is started again.

marinizing has nothing to do with pistons or rings.

furthermore, it appears that GM, by their own admission, marinizes their engines before Merc, Indmar, PCM, etc get said engines to rebrand them

if your assertion is true that GM cranks them in the factory, then we should be safe.

Are we splitting hairs here, yes we are.

The higher price only makes my point even more valid.

if both are the above are true, then you quickly reach the point of diminishing returns with regards to the higher price assertion, but i digress. all of my boats have been outside of their break in window hours when i took delivery of them, and all have run like raped apes. i still stand by my assertion that GM, PCM, and CC are not going to leave their reputations to us and various correct or incorrect break in techniques... (for the record i am not espousing hope as a method)
