Let me suggest a rebuilt aluminum prop to save a few bucks (bought one
myself here in Ottawa .... Black Max 23" pitch @ $120) and a breakaway hub
kit ... I found a pic here ...

toolkit.

Hello group.
I just bought a boat after being out of it for about 15 years so I am a
little rusty at some of this stuff so I thought I would turn to the
experts.
I have a 26' 1978 Sea Ray sundancer express cruiser with a 260 hp 350
chevy
engine. The boat engine will only put out about 4100 rpms if it is not
going
into the wind and might get up to 22 mph and does not seem to plane well.
I
thought it felt like it was not winding up like it should. According to
the
mercruiser book for the boat the max RPM should be 4600 RPM. I took the
prop
off today and it is a 17 pitch prop but I dont know the diameter. The
number
off the prop is 48-79572-17. I don't know what prop it should have on it.
I
called several Sea RAy dealers and they could not give me an answer which
I
thought was odd. I am wondering if it is over pitched and how far should I
drop it down? Thanks for any help you can offer.
John
