The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Beware of propmd.com. Bought a prop from them that they suggested would be the best for my set up. Turns out my engine overrevs now and performance is down. They will not accept return because it has been used on the engine. Just thought I would give a heads up.
I have a 2005 Mercury 4 stroke bigfoot with a 14X11 prop. I would like more RPMs out of the motor, presently it is 5400. I am going to put on a Black Diamond 14X10 cupped prop. Can anyone tell me what I can expect in RPM change?
Thanks
