Welcome to the Tige family. Here is a post that may help you.

There is a specific break-in procedure for the first 5 through 25 hours in the PCM manual, my dealer went over the instructions step by step. Also make sure you fill out the warranty cards for both the boat and the engine. Welcome, I picked my boat up 3 weeks ago so I'm relatively new to the site as well, there is to s of great info here.

Anyone ever consider using some of the royal purple break in oil?

I would spend my money on Crown Royal and just drive the boat as you normally would, but just my opinion.

In all my years as a professionally technician, I have never know anybody that ever fallowed the break-in for their car. I've torn down a ton of engines, and not one failure could ever be contributed to a poor break in period. IMO, if the engine leaves the assembly plant correctly built, it will never fail as a result of not fallowing a breaking procedure. On the other hand, if the engine was not assembled correctly, or had a defect in an internal part, no amount of "breaking" driving will prevent the inevitable.

Proper maintainence has more to do with an engine life span then anything.

This is a tricky subject and this website explains it very well. I was an environmental engineering major in college and not a mechanical engineer, nor am I a licensed mechanic. I did take the basic engineering classes in physics, thermodynamics and intro to mechanical engineering and this method makes sense to me. I have used it to break in my G35 and my wife's 4runner and I was surprised to read in the PCM owners manual a similar procedure to break in the engine. The basic procedure is to put the engine under load very early in its life to properly set the piston rings. This procedure makes no claims to make your engine last longer, it just attempts to set the rings to prevent loss of compression and squeak the most power possible from the engine.

I followed the PCM procedure 'cause I thought it was setting the rings properly to get the most out of the engine. Just like chpthril said, it's probably not going to cause your engine to run poorly or fail prematurely because you didn't follow the break-in procedures. It is a controversial subject that will have many strong opinions and it took a lot of surfing the web and a buddy with a masters in internal combustion engine design to convince me the procedure linked is good for my vehicles.

Thanks all

eh just wondered if it would help at all. Ill do some research and see if the stuff actually works on cars, doubt it makes a huge difference, but who knows?

sorry to post twice, but interesting read man. Makes sense, I still find it hard to believe ALL the auto manufacturers wouldnt be all over this, im skeptical, but will have to think about it awhile ago.
Im studying to be a mechanical Engineer, If i get to the point where I can let you guys know, I will!

I just had a new motor put in my ride and they said pretty much to run it under load by pulling, but not to keep it at the same RPM all the time, and no WOT for more than 5 seconds.

Pretty much use it as normal, just bring it back @ 25 hrs so we can put multi-weight oil back in it.
