Baller LK_skier Posted September 12, 2022 Baller Share Posted September 12, 2022 What prop is everyone running on the SN 200 with a 5.7? And does a prop impact the wash size and feel? My boats wash feels substantially "harder" or bigger than other 200's I've skied with - its an Open Bow - wonder if they are heavier than the closed bow? When my fuel is very low it feels a lot better but anything over a quarter feels harsh. Tricker's love the wash but I'm not tricking. Link to comment Share on other sites More sharing options...
Baller Kenboat Posted September 12, 2022 Baller Share Posted September 12, 2022 Run a AMCE 422 on my 2012 with 343 PMC. Provides a nice wake and the boat tops at 43 mph 5000 rpm. This is not he stock prop but after market. Link to comment Share on other sites More sharing options...
Baller BlueSki Posted September 12, 2022 Baller Share Posted September 12, 2022 I also run a 422. The wake is soft, people compliment the pull, and I fill the gas tank. When Nautique released the 200, they said the open bow and closed bow had the same weight. I do have a 50 lb weight from Lead Wake in the nose.

Baller dave2ball Posted September 12, 2022 Baller Share Posted September 12, 2022 654 was the prop of choice from the factory. It was on all promotional boats prior to going to the current 5.3 motor. Link to comment Share on other sites More sharing options...
Baller KRoundy Posted September 12, 2022 Baller Share Posted September 12, 2022 I think 654 and 422 are the choices you have. If you have one and don’t like it try the other. I have a 2016 OB with the H5 propped with the 654 and love it. Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted September 12, 2022 Baller_ Share Posted September 12, 2022 whats your elevation? Link to comment Share on other sites More sharing options...
Baller dbutcher Posted September 12, 2022 Baller Share Posted September 12, 2022 I use the 654 on my 2015 SN200, 5.7L engine, and it works well. If memory serves, the 422 was (is) the prop for 196's. My guess is that the 422 would not be quite as peppy out of the hole as the 654 on 200's. Use what you like best. Link to comment Share on other sites More sharing options...
Baller ScarletArrow Posted September 12, 2022 Baller Share Posted September 12, 2022 I had the original 1868, then the 422, then settled on the 654. Link to comment Share on other sites More sharing options...
Baller BlueSki Posted September 12, 2022 Baller Share Posted September 12, 2022 @ScarletArrow, what do you like about the 654 over the 422? I have thought about trying that one. Link to comment Share on other sites More sharing options...
Baller jpwhit Posted September 13, 2022 Baller Share Posted September 13, 2022 The 1868 was the original factory prop and tournament approved prop on the 5.7L 200 when it came out. But the boat ran fairly high RPMs with that prop. Around 2013 they switched the factory default prop to the 654 and that was also the tournament approved prop starting the year they switched. It brought the RPMs down to a more reasonable level. I tried the 1868, 422, and 654 on my first 200 (2011 model) and I ended up also running the 654. It just felt best with that prop. The 200 I have now, with the 5.7L also has a 654 on it. Link to comment Share on other sites More sharing options...
Baller LK_skier Posted September 13, 2022 Author Baller Share Posted September 13, 2022 @Jody_Seal - not much elevation here in Brisbane Aust - It's got a 654 on it - seems to be the correct prop. The wash just doesn't feel as nice as a 2012 200 I also ski behind. At all speeds and all rope lengths - the kids say the other 200 is better at their slower speeds and I agree at 34 as well.I tow @JoelHowley at 58 he agrees too... maybe its not the prop - could be the hydrogate? that is suppose to be level with the hull when in slalom mode? At really low fuel it is better - the fuel tank position wouldn't have moved? Previous owner was a mad tricker so my random theory is they may have adjusted something to make it a nice trick wash?

Baller rockdog Posted September 13, 2022 Baller Share Posted September 13, 2022 If it's that obvious then first thing to do is check the hydrogate for sure. It can't be much else unless one has a weight in it that you don't know about. Link to comment Share on other sites More sharing options...
Baller JoelHowley Posted September 13, 2022 Baller Share Posted September 13, 2022 Yep... This boat sure does have a bigger wake than my closed bow 6L 200. We have the same 654 prop and both hydrogates are flush with the hull. Link to comment Share on other sites More sharing options...

Baller ScarletArrow Posted September 13, 2022 Baller Share Posted September 13, 2022 @BlueSki as mentioned above I thought it brought the RPMs down best and felt like it was quieter. Not a scientific assessment just a feel. My 422 got damaged so I replaced with 654 as an experiment based on feedback from this board (still have 1868 as emergency backup). I pull some heavy and short line skiers and no one noticed a (negative) difference in performance. Link to comment Share on other sites More sharing options...
Baller MopedMedicks Posted September 13, 2022 Baller Share Posted September 13, 2022 As a different approach, has anyone tried the 3 blade version of the 654? That would be the acme 470. Same diameter, pitch, and cup. May be marginally faster too? Link to comment Share on other sites More sharing options...
Baller jjackkrash Posted September 13, 2022 Baller Share Posted September 13, 2022 A few possibilities:The hydrogate is misadjusted at rest or somehow not in the proper place when the boat is running at speed. Even small variations on the hydrogate have a big impact on the wake. Maybe check this again with a straight edge at rest. There is weight hiding in the boat somewhere maybe in the bow storage or maybe water in the bilge, etc. There is a hull defect like "hook" or sag somewhere in the wetted running surface. Check the wetted running surface especially from the transom forward a few feet with a straight edge and make sure it has not developed a defect. Note, a hull defect is unlikely but not impossible in a tow boat especially if it was stored on a lift improperly at some point in its lifetime, like with excessive weight or insufficient or improperly located support. A little hook near the transom could easily impact the wake. Link to comment Share on other sites More sharing options...

Baller dan1166 Posted September 16, 2022 Baller Share Posted September 16, 2022 I have a 2016 Ski 200 with the 6.2 liter engine. It came with a 668 ACME. I notice a little vibration on a very hard pull with a heavy skier. However it does smooth out when on plain. Is this normal, or would a different prop eliminate the vibration. Shaft alignment was done and everything else was checked out at the dealer. My friend has the 343 engine with a 422 and that boat runs very smooth.

Baller LK_skier Posted September 16, 2022 Author Baller Share Posted September 16, 2022 @dan1166 - not normal. You might need to have the prop and or the prop shaft checked - or engine alignment Link to comment Share on other sites More sharing options...
Baller jpwhit Posted September 16, 2022 Baller Share Posted September 16, 2022 @dan1166 it's not that unusual. Typically caused by uneven flexing of the prop blade under heavy load. The more powerful the engine, the more likely it is to happen. It's not that surprising on a 6.2L. It can very from one prop to another. Another 668 prop may behave differently. You may want to call ACME and discuss the situation. Link to comment Share on other sites More sharing options...
Baller jpwhit Posted September 16, 2022 Baller Share Posted September 16, 2022 I should have asked if the prop and ever been damaged or had any repair done. It's almost alway the case on a repaired prop. Because the process of reworking one blade more then the rest changes the strength of the metal slightly. But it can also happen on a virgin prop that never been reworked. Link to comment Share on other sites More sharing options...
Baller dan1166 Posted September 16, 2022 Baller Share Posted September 16, 2022 It was never reworked. I hate to purchase another prop only to find the same situation. That is why I was thinking of another size prop. It is my understanding that the 668 is a .150 cup while all others are.100 or .125. Please understand that on a normal pull, it does not vibrate.Thanks for your input. It makes a lot of sense to me. Link to comment Share on other sites More sharing options...
Baller skierjp Posted September 16, 2022 Baller Share Posted September 16, 2022 @dan1166 I have had at last count I think 6 Nautiques with the 6.2 and the 668. What you are experiencing is normal and you will feel this on every boat. It happens on full throttle. What you are feeling is the propeller cavitating. In all the driving I do I hardly ever apply full throttle to a skier on a deep water start. Link to comment Share on other sites More sharing options...
Baller scoke Posted September 16, 2022 Baller Share Posted September 16, 2022 Are you running a single puck or dual? It makes a difference in other areas. 1 Link to comment Share on other sites More sharing options...

Baller Killer Posted September 17, 2022 Baller Share Posted September 17, 2022 6.2 200 I run does the same. Runs smooth after that initial pull up and worse with a heavy skier. Odd but seems typical Link to comment Share on other sites More sharing options...
