Impeller replacement

[camocajun]

i replaced impeller and tuned up my 150hp at the beginning of last year. However i did not use boat much at all last year. do i still need to replaced the impeller this year even thought has very few hours on it. im still going to do all filters and spark plugs this year.
Thanks mike

Your impeller should still be good to go, maybe change every other year or so, depending on boat usage. Your spark plugs are probably still good also, but it won't hurt to pull them out for an inspection and cleaning. The filters are always worth a check and cleaning.

In replacing the impeller, the maint book does not refer to this specific engine or say if you put it in gear or not. does anyone know the procedure for an engine like this one?
