Well i'm sure this is a subject that has come up a time or 20.Here is my question to anyone who has the knowledge that could help.
I have a marina that sells used and new outboards,they also specialize in rebuilds.I read my manual on my new 9.9hp 2stroke yamaha and it says idle only for the first ten minutes,then the rest of it as most people know with half throttle for a period,then 3/4throttle for a period etc.....
I talked to this guy at my marina who told me the most important time in an outboards life is the fist hr,whether it's a 2 or 4stroke.
He told me to disgard what the manual says and idle under load in f gear for a full hr as that is the most critical time.He said the fist hr of the lifes motor is to fully lubricate the motor from powerhead to the lower unit.He makes a good valid point by saying 10 minutes is not good enough to do so.I was just wondering if anyone has heard of this?To idle slow for the first hr instead of just 10minutes.He said after the first hr of idle then follow what the manual says,but make sure you idle for a full hr first.He said it will make or break the life and performance of the engine.
I'm trying to find out if there is any truth to this.I would really like to hear some opinions or if anyone has some good facts.Thanks
