I've been having bogging problems on my 1979 80 merc. The boat is a sea nymph 17ft aluminium . The prop on the boat is marked 48 77350a4 23p is this close to being the right prop for this boat motor combination

My first impression is that it might be a bit steep but it could be right. What's the top rpm?

I agree the prop may be a bit steep, but I doubt it would cause your motor to "bog down". You may be in need of a tuneup, fresh gas, fuel filter, fuel pump, etc.
