prop rotation for surfing

[fech98]

Here is where I am at...I have an 04 211 with a RH prop rotation, the boat is at the shop and thinking about doing a LH prop rotation. The wave on the starboard side is great just with stock ballast, the port side is almost nonexistent. I have tried all types of set-ups, but before I do this, would the LH prop rotation make my port side wave cleaner? Any thoughts????

Without any science to prove it all things being equal between a LH and RH setup yes it would be cleaner. But for the expense of changing your rotation I'd say just add more weight.

I am currently running 900 pounds on the left walk through. 300 pounds under the left side seats. I have about 200 pounds upfront and then all people on the left side. And I can still see the water wants to go to the Starbord side. I am currently looking at my fins underneath to make sure everything is straight. But if the boat was completely empty and no ballast is Filled the wake should be proportionate or close. Mine is so far off

[wakeslasher69]

What speed are you running? My only thought on setup is a little more weight under the seats. Basically the RH twist offsets the driver when running empty with no people aboard so you are 'neutral' at that point where someone with LH twist and a driver is already pushing down the starboard (right) side.

Well correct me if I am wrong but having a RH rotation would kick a wave to the starboard side and LH would kick water to the port correct? So LH is better for port side surfing and should balance out the driver of the boat?

With your setup you should have a decent port wake. I have tank busted, so have 750 in port locker, about 300 under passenger seat, and center tank full. With my daughter driving and wife+12 yo sitting on port side, I get a decent wave. One more adult on the port seat and I am happy.

When we surf starboard side I don't need the weight under the passenger seat, but just move people and have the starboard 750 and center full.

Once I have a couple more adults it gets nice and big... Or when my homemade NSS was working it was amazing. But you can get a decent port side wave with what you have. The top isn't going to be real "clean" but you may want to try moving some more weight forward. 900 in the back may be making it too steep. We usually play with the speed and wake plate a bit to try and get it clean before someone jumps out behind the boat.

Changing the prop rotation seems really complex and expensive. Just teach people to surf goofy. That is what we are working on now.

I agree with you, but unfortunately I am not for some reason not sure why? I have adjusted weights speed wake plate people turns so my last solution was the prop. But would hate to not know if this could fix the problem. I am just looking for clean water but just a level ride

fech98 your prop rotation question (post #5) is backwards. If you have LH rotation the boat is pushing down on the starboard side which will make a larger goofy side wave, RH will make a better port wave.

[fech98]

Ddipert right now my Starboard side wave is ridiculously bigger than my portside wave.... How is that possible with a RH Prop rotation? This is with no ballast in it as well. When I add stock ballast to either side my starboard wave is bigger. On other threads people said LH is better for portside. So which is it?

[fech98]

So overall which is better for portside surfing a LH or RH???

LH. Both my past 211 and current 210 are LH prop and the port side surf wave is best.

Am I reading this right? I don't think you can just change prop rotation that easy.....

Fech98, with the weight you have in the back try adding 200-400 additional lbs to the bow. Aim for a 60-40 split. That will lengthen your pocket and help clean up both port and starboard waves. Maintain that distro front to rear and play with the list side to side to tweak it from there. I have a 226 with RH. Variations of that setup work well for me, but I also just ride switch / goofy when I surf to make it so I can avoid a bag in the seat. (1,100 fits in starboard locker).

Yes I was wondering the same thing. Pretty sure you'd have to put in a new transmission, v drive and prop. Also might need a new shaft if it is press fit and removal does not go well. LH props will make a better port surf wave but it seems like a very expensive mod to make for that. Also your boat was designed to spin a RH prop so switching directions could potentially lead to handling issues.

Your comment about your boat not running level when the ballast is empty seems odd. Does it sit level in the water with nobody on board? If it lists one way then perhaps you have wet foam that is throwing off the balance.

[fech98]

Price wise on switching the prop rotation isnt too bad, but the boat sits in the water level, it rides level, no issues there...
