Baller tru-jack Posted June 6, 2018 Baller Share Posted June 6, 2018 Getting close to getting a 5.3 200, and can't seem to get an answer: what are the rpms at 34mph? we ski a 5.7 200 and it spins about 3900rpm at 34 which is pretty high with lots of vibration and fuel consumption. Can someone put me at ease that the 5.3 is an improvement in this regard. Thanks Link to comment Share on other sites More sharing options...
Baller Kelvin Posted June 6, 2018 Baller Share Posted June 6, 2018 Which prop do you have on the 5.7 200? Link to comment Share on other sites More sharing options...
Baller bkreis Posted June 6, 2018 Baller Share Posted June 6, 2018 mine runs 3400-3600ish Link to comment Share on other sites More sharing options...
Baller Kelvin Posted June 6, 2018 Baller Share Posted June 6, 2018 The original Acme 1868 14.25" pitch was notorious for high RPMs. Most 200s that I know of have switched to the Acme 654 15" pitch prop on the 5.7L engines. That lowers the RPMs to the range mentioned by @bkreis Link to comment Share on other sites More sharing options...
Baller ntx Posted June 6, 2018 Baller Share Posted June 6, 2018 @tru-jack we had a 5.7 in a 2014 200 and also a 5.3 in a 2016 200. The 5.3 is a MUCH better option. Better on short set up and a MUCH improved jump boat. Link to comment Share on other sites More sharing options...
Baller tru-jack Posted June 6, 2018 Author Baller Share Posted June 6, 2018 thanks, not sure of prop on current 200. it's a member in our club, and not my boat. it's a 2011 I believe. it will be a slalom boat, not jump, but am hoping to not spend as much on fuel. currently have a 2007 lxi and it's great on fuel compared to the 2011 200. We're in Canada, and gas is expensive... Link to comment Share on other sites More sharing options...
Baller jjackkrash Posted June 7, 2018 Baller Share Posted June 7, 2018 Also note the H5 is direct injected and supposedly more fuel efficient than old tech, and revs to 5600 rpm before it hits redline. Link to comment Share on other sites More sharing options...
Baller LeonL Posted June 7, 2018 Baller Share Posted June 7, 2018 I can't read the RPM on @Gloersen video. I'll be driving a 2017 5.3 this afternoon. I'll watch the tach on the ZO head. The factory tach is WAY off on the high side. Always has been. Link to comment Share on other sites More sharing options...
Baller dave2ball Posted June 7, 2018 Baller Share Posted June 7, 2018 The rpms are around 3700 with out the load of a skier. The 1868 prop with a 5.7 was over 4000 You won’t have a problem. Link to comment Share on other sites More sharing options...
Baller B_S Posted June 7, 2018 Baller Share Posted June 7, 2018 I have the 5.3 H5 in my '16 200. Shows about 3800 @ 34.2. No complaints about fuel consumption, much better than my previous carbed '92! It's a fantastic, torquey, responsive engine that fits this boat well!

Members brettmainer Posted June 8, 2018 Members Share Posted June 8, 2018 I have owned 200s with the 5.7 and currently have a 2016 200 with a 5.3 H5. The 5.3 is better in every regard save initial purchase price. The fuel economy is noticeably better with the 5.3. Link to comment Share on other sites More sharing options...
Baller mbabiash Posted June 8, 2018 Baller Share Posted June 8, 2018 The 5.3 is tough on big guys. I’m 220 lbs and the 5.3 nautique is a noticeably harsher pull than any other boat or any other engine in the nautique. Link to comment Share on other sites More sharing options...
Baller Ski_Dad Posted June 8, 2018 Baller Share Posted June 8, 2018 @tru-jack wouldn't the rpm be dependent on the prop ? I'm not sure if the engine will make any difference in that. I've noticed that my friends 200 with 5.7 put you about 3950 when a skier is at 34. That is with a 654 prop. Maybe in your situation with the extra power a 422 prop would be in order to drop the rpm say 150 ? Link to comment Share on other sites More sharing options...
Baller blakeyates Posted June 11, 2018 Baller Share Posted June 11, 2018 @tru-jack , it’s the prop. I had a 2011 Nautique 200 Promo Boat and the RPM’s were so high that I changed the prop and then all was fine. Get the Acme 654 and you’ll be fine. I have a brand new one that I would consider selling because I need to buy a 668 for my 6.2 H6 Nautique Promo Boat so I will have a spare. To answer your original question, I don’t know my rpm’s but I “do know” it fixes the problem and all will be well. Link to comment Share on other sites More sharing options...
