Customer Question

I have a Yamaha T9.9gplh and I don't understand what gplh or any of the letter designations stand for. Can I get a full list of all letter designations stand for. I also have a 175 Hpdi. I love Yamaha, just want to understand them better. Is the a reference other than Yamaha owners manuals.....they are too general and they website does not address. Dealers don't want to hassle with such petty questions.
Thanks for your help.
