Re: prop pitch?

Bases on my Merc 150hp straight 6 (Chevy 230), all of the parts that I've
ever needed came from a typical auto parts store. Most generic things, like
the fuel pump, starter, and points have come from AutoZone. The carb
rebuild kits that I have used came from NAPA. AutoZone doesn't like to hear
"marine application", so I just figure out what car had that same motor, and
ask for that part. For the 155hp, a 1965 Buick Skylark with a 225cid V6
should do it. AutoZone.com states that a new waterpump, with a limited
lifetime warranty, is 54.99.

Hope that this helps.
