1) Fuel octane - For the 155 HP use 87 octane in North America, 91 RON outside North America. For the 185 and 215 HP models the RECOMMENDED fuel grade to use is 91 octane in North America, 95 RON outside North America. You can use the lower octane/RON fuel in the supercharged engines HOWEVER the timing may be retarded if the spark knock sensor determines lower octane.
2) Learning Key - The electronics of a sport boat do allow a learning key to be programmed however the learning key is set to limit RPM to 5,400 and is not adjustable. The same limits are applicable to personal watercraft. It is not a good idea to break in a boat or PWC on the learning key. Even the operators manual recommends "brief acceleration and speed variations" over 3/4 throttle and that it will "contribute to a good break-in".
3) Break In - We recommend using the entire RPM range however don't stay at any given RPM for more that 20 to 30 seconds at a time. Try not to cruise at a fixed speed. Do this for the first 2 tanks of fuel and you will find that the engine has better compression later on in it's life. We have tested the compression on boats that were broken in by using the learning key or some other non recommended procedure and found that the engine compression is lower than a boat properly done. This applies to 2 and 4 stroke engines, Mercury and Rotax.

This forum is GREAT....thanks to all for the great info.
Oh, as for the performance, it met all my expectations...at least for the break in period. The sucker tracks like nothing else I've driven or ridden in. I call it my floating hot tub. For the winter, I think I'll fill it with hot water and sit in it after snowboarding!!

breaking them in gently regardless of what anybody else says is surely the best thing to do -

By my description, do you think I was too hard on it? I'm new to this boat but I think I was pretty easy on it. I always eased into the rpms and never "gunned" it in order to get to speed. I tapped 6K a few times but never really stayed on it. I'd say that for most of the day, I stayed between 4K and 5K rpm's or lower. Any advice would be helpful.
