I have an 1987 A27 Sport with the 6 BD1 engine and 1 1/2" shaft. It currently has a propeller that I believe was modified to fit this boat but not sure if it is the best size. It is a 4 bladed 18" RH with a pitch of 20. Anybody have the specs on what works best for them and what they might have for rpm/cruising speeds?
Thanks,
Joe

Re: propeller size on A27
For comparison purposes, and maybe more, contact your local prop shop since they have all the tools/programs to determine the right prop. You'll have to provide details about your boat/engine/transmission, etc.
If you've already done this and are looking for confirmation, my apologies.

Re: propeller size on A27
Wow, that Isuzu has almost two and a half times the horsepower of the 4D61 in our 27FC, so anything I know about ours would be of little help to you. As Willie says, a good prop shop could help, or I would recommend reading "The Propeller Handbook" by Dave Gerr. That's a fine introduction to a fascinating subject: or the entrance into a black hole of endless speculation -- whichever you prefer!
