I have a 1991 baja 204.It has a 4.3 mercruiser 4barrel. right now the prop on it is a 13.75 dia 21pitch. I would like to have more bottom end power for getting on plane faster without sacrificing too much top end speed thanks.

Re: baja prop swap

What are your current RPMS at top speed, and what is your top speed?

Re: baja prop swap

Assuming you're turning your current prop on the high side of the recommended rev range (and you should be), try a Turbo 2+2TH, 20 pitch. A lot of us have run this prop successfully on the + or - 20 foot Bajas. You'll lose a mile or two and a hundred rpm on top but every other aspect of performance is a lot better.

Again....this recommendation is assuming you're propped right now. If not then need to address that. Always good to post up rpm and gps speed at WOT with any request for prop info.
