View Full Version : top speed issue 94 205

08-10-2011, 11:37 AM
I have just replaced my trans cooler and have gotten all the water out. However, it seems like I get 2-3 mph more on top end when I turn slightly starboard. I have a 4 blade prop and 40-42 is max but turning slightly only starboard gets me 43-44.
I recently calibrated speedos with GPS.

Any help would be appreciated.

maybe it is because you are turning the same way the earth rotates. :-)

turning downhill??

paint flames on it and really loud exhaust. that will make it faster!!

I bet if he bought a Nautique it would be faster when turning to the port side than starboard

I think the SN would just go faster whether or not it was turning. ;)

Are you seeing a jump from both speedometers or just one?

Both speedos.

But yes I was going south on lake lanier so it had to be downhill ya buncha smart as** but I deserve cause I'm one too

Do you have any hull damage on the port side, such that when you turn to starboard the damaged area gets lifted out of the water?

Perhaps damage to the rudder such that a slight turn to starboard moves the damaged section out of the waterflow?

Otherwise, I'm out of ideas.

Its called P-factor.

I know this refers to aircraft but the principle is the same. Our propellers are at an angle to the relative flow of the water when on plane.

Ok that makes sense missilemech

The real answer is easy ... Pv =nRT .... Duh
