I have the stock propeller on my Volvo SX I/O. <BR> <BR>I have one of those tail thingy's but will a new propeller help plane faster? I am thinking about buying Perfect Pass too.

If you reduce pitch by 2" you will get on plane faster. PP will hold speed better, especially at wakeboarding speeds.

Go to OJ propellers website and contact them to get you set up with the right propeller. skiertoskier.com is a good place to buy their products.

Another option would be to contact <a href="http://www.propellersonline.com/" target="_blank">http://www.propellersonline.com/</a> . If you tell them about your boat and what you want to run for weight they'll recommend the best prop for the situation. In my case it made a night and day difference after upgrading my ballast.

I would not get an OJ prop again. IMO acme is better.

Acme and OJ do not make IO props. Michigan Wheel, Solas, etc.
