That sounds much too slow to me. That motor should hit the mid-5000 RPM
range at WOT. It sounds as if you're overpropped and need to drop down a
couple of inches in pitch. What size prop are you using?

Go to continuouswave.com, login to the forums, and ask your question in the
"performance" section. It's a Boston Whaler forum, and chances are that
someone there has the same exact set-up as you. If not, there are a lot of
guys there who seem to know a bunch about Props, particularly Mercury props.

I have 23' 2000 Outrage, 225 Merc Optimax. The boat will go 29 Knots
@ 5000RPM. Is this about what I should expect for a speed or will a
different prop pitch make this higher (without suffering at the low
end too much).

What effect does twin engines have for top speed?

Thanks,
Jon
