break in

[5150abf]

So I am up 5.1 hours on the new engine, 2018 F50, break in instructions say to avoid idling for long periods.

We go to a local lake, actually 3 lakes connected the second lake we spend most our time on is no wake and it takes 10-15 minutes to cross to get to the sand bar at 1500-2000 rpm.

Periodically I will pop it into neutral and let it spin at 3000-4000 for 15-20 seconds.

Is that good or bad to do and would it be better to just putter.

First new engine and first 4 stroke.

I figure during break in you are setting the future reliability of the engine and I don't want to create problems down the road like "making oil"

Rpms should be loaded

So that isn't really doing anything then?

I thought it would be better than just idling.

Am I correct in thinking that is what causes it to make oil is not breaking it in hard enough.

On the river I do run it wide open for the 5 minutes.then drop down to 4000 for a few minutes.

There is no point in running a motor in neutral at 4000 RPM

most people just spend a day or two running thru the break in to get it out of the way and then run it like you want to
