Subject: Wake much higher on one side

| I have a 1977 Ski Nautique with 351 Ford Windsor with reverse rotation (looking back at front of engine, rotates counter-clock wise). At speeds of 25-40 mph, the wake spray on the passenger side is much higher than on the driver side. I can see how the prop rotation could cause some of this but it seems to be much too high. When sitting still in the water the boat seems to be level as I have wondered if water could be in the space on that side of the boat? Is this something a cavitation plate on the rear of the boat could correct? |

that's "normal". you just need to balance the crew in the boat (i'm assuming you get this high spray when it's just you in the boat, driving) the reverse rotation engine/RH prop is actually working to minimize this exact issue ------------- |

More info needed. How many in the boat? Just a driver or more. If there was more than one person in the boat was the weight evenly distributed or was there a definite advantage to one side? There's been countless discussions here for many years about CC using RR motors to counteract a solo driver. Some owners here say theirs run fine, others have your problem. I believe the general consensus is that each hull may have encountered some minor differences during the manufacturing process. In other words, no two hulls are exactly identicle. Maybe new ones are now but certainly not back then. I personally don't buy any of it because then you should have problems when more than a single driver is in the boat. I've persoanally never driven an inboard that doesn't list when just a driver is in it or unevenly weighted to one side. Not saying they don't exist, I've just never experienced it. Then, that's morphed into discussions about changing out the RR engines to standard rotation. Again, I've heard some say they've done it without a problem but more that have had pretty severe listing and handling issues after a change like that. A '77 like yours is a very narrow hull that can change the wake shapes pretty dramatically with minor weight shifting. This is something we all have do when pulling a skier to even out the wakes. I'm sure this will open up another in the long list of these same discussions but if you were the only one in the boat, or there is a definite weight advantage to one side, I think it's normal. ------------- When people run down to the lake to see what's making that noise, you've succeeded.

George, First, I'd like to welcome you to CCfan. The site is fantastic with a fantastic knowledge base with many members as well as plenty of info in the reference section. Please, how about posting some pictures! we love them. An addition to the diary section would also be a fantastic contribution. As Eddie mentioned, balance in a 77 is pretty critical in a hull that was designed as a ski boat. Fill us in on how many people you are putting in the boat and where. The design is basically for the the driver and spotter. If you are going beyond that, then truthfully you do not have the hull/boat you need. You have a SKI boat!!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| The wake being higher on the passenger side was when two people were in the boat. One driving maybe 180-190lbs and myself in the observer seat at 215pounds. Stayed pretty much the same when I slid over to the middle. I plan on using the boat in the next week or two so will do some checking to see if 2-3 people on the drivers side even the boat out. As for posting a picture, I read in the forum help that unless the administrator has allowed posting of pictures, one must use a off forum site to link to? Otherwise, I don't see how to post a picture? Also didn't see where pictures are being posted below the forum members screen name - must be in the member setup? |

Wrong! Go to "post reply" and not "quick reply". Click on the icon with the tree with the up arrow. Regarding the " pictures are being posted below the forum members screen name - must be in the member setup", you need to set up a diary first. Take some time and explore the site and learn. Searches are a fantastic tool. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Ski boats (inboard tournament type) were designed to be operated in the 25 to 36 mph range with a driver and a timer and a judge on board. The latter two facing aft on a love seat, driver solo facing forward. Any variation from this will alter the wake characteristics and performance of the boat. Some I/O's and outboard boats had the judge seated behind the driver and the timer on the portside so they could hold a stopwatch over the side and click it as they entered the slalom or jump course. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=4487" rel="nofollow - 1998 Ski Nautique |

Are your skegs (fins on the underside of the boat) straight? A bent skeg "could" cause a list under power. |

Count me as confused. What does this mean?
Is the boat itself leaning at speed? If so, which way is it leaning? All of the comments thus far discuss reasons why the boat is leaning one way or the other, but Im not sure thats what the problem is. You talk about moving the driver over to the middle, then talk about adding more weight to the drivers side... those would have opposite effects, when it should be pretty clear which side of the boat would need additional weight if the boat itself were leaning. Are you talking instead about spray? Off the side of the boat, or off the prop? Just behind the boat? The rooster tail? Or are you talking about the wake itself? Some pictures and a better description of what youre trying to address would be really helpful. Though, the answer to your question (will a cavitation plate correct this?) is almost undoubtedly NO. ------------- |

<- x2 confused Usually the high side of a listed boat puts out a higher spray but that's not how the OP seems to be describing the situation. ------------- |
