I have a few problems that I could really use some help on.<br />First is that if i accelerate to fast, the motor will over rev, and seems to pop out of gear, although there is no real "popping", but when I drop down to neutral and then start to accelerate again (slower) all is usually fine. Is this normal, and if not, then what may be the cause of it?<br />Next is the year. I have done a ton of searching and calling dealers to try to find out what year this motor is, but have had no luck. The serial number is B197555. Hopefully someone can tell me.<br />Lastly, I am hoping that someone can tell me the low and high RPM's reccomended for this engine, so that I am sure that I have the correct prop on it, or can get the correct one.<br />Thank you for reading, and I really do appreciate any and all help that you can give me.<br />Thanks,<br />Russ
