You are correct Mike. For max top end speed you want to prop with a good
performance SS prop at about 300 rpms below max rated. This will give you
the best top speed but will hurt your hole shot some.

In article xcgQc.246823$XM6.7643@attbi_s53, says...
A 4 blade prop of the same pitch will be slower on top end due to the
extra
blade surface (althought a 4 blade will usually be smaller in diameter
to
help compensate - it still will be slower on top end).
A 4 blade prop of the same pitch will be faster out of the hole due to
less
slippage. A 4 blade is more efficient at lower rpms.

If your not comparing same pitch then all bets are off.




Ok then, if I understand this properly, if my main interest is strictly
fishing and towing a joy rider is only the faintest of possibilities and
assuming the same pith I'd be better served by a three bladed prop since
good hole shots are not a necessity but getting from one spot to another
in the fastest most efficient way would be?

Thanks again for the info.
