I am a believer in a semi hard break in,Im am not saying this is the best way, but this is how I break mine in........
I run mine on the hose through a couple of heat cycles,run it till it gets warm, let it cool off a couple of times, then take it to the water let it get up to operating temps idling around, then get it up on plane@ 30-35 mph and do about 20 minutes of hard pulls almost to WOT and slow back down quickly to @ 30 mph and keep doing that, after the 20 mins I just vary the RPMs (no sustained WOT) for the next 5 hours, then ride the hell out of it.

I would go with TN's recommendation; I babied mine like a bitch and I got the famous GIO* (Gas in Oil) problem; he has none, although I'm at 50 hours and have zero issues other than that.

The first part of the breakin sounds good.... After 2 tanks of gas.... Run it.

I broke mine in similar to how Harry did his other than the heat cycles on the hose. I didn't baby it at all although I didn't run the hell out of it untill
I had a few hours on the clock. Mostly a lot of short full throttle pulls and a lot of varied rpm's. I don't know if break in has anything to do with the GIO problem but I didn't have it nearly as bad as some did who took it easy during break in. Mine was also faster than most when it was stock (67.5) so maybe a hard break in isn't such a bad thing.

There was an article posted on PWC Offshore that explains why going too easy during break in can impair good ring seal. I cant find it now but I know its been linked and discussed before. That article helped me understand the possible connection between soft break in and GIO. One point of clarification though TN250. After a few cycles on hose in driveway, during the first 5 hours on water, is it important to shut ski off and let it cool down repeatedly? I want to break in new engine during one long day of riding in next few weekends. Air temps will probably be 45 or 50 at most. Should I stop a few times every hour and let it cool down or is that unnecessary given cool air temps? Thanks.
