| All, I have recently purchased a 1993 Stratos 274 DC bass boat, 17.5' long.
It came with what I was told
was a stock motor -- 150 HP Evinrude. The seller had changed the prop to a spare he had -- 25 pitch, 13.5",
4 blade propeller. The boat
now has a hole shot that takes a long time, bow wayyyyyy up until you
nurse back power a bit to
bring it on plane. It generates 4400 rpms and reaches about 50 mph via
gps (MFG range is 4500-5500 RPM at WOT). It has a jackplate and
I've raised it from about 6 inches to about 4 currently. Does anyone know what the original prop would be? If not, does anyone
have any advice about
what I should try next? What I've read online suggests this: *get RPM's up first -- and that reducing pitch by 1" = 200 RPM's on
average. So I'm thinking dropping
pitch by 3-4" is the right place to be, or in my case either a 21 or
22" prop. *blades -- 3 or 4?? I have no idea what the difference might be. *diameter: I have no idea. Thanks much!! Please reply to readmeray@mac.com |
