Baller jedgell Posted August 20, 2013 Baller Share Posted August 20, 2013 Our club bought a 2013 CP a couple months ago, great boat. We've noticed that our fuel consumption is up 10-15% compared to the 196 we had before. It turns about 3,700 rpm at 34 mph. Is this normal? I thought it would be closer to 3,400. Also, the top speed is only 43, not that it matters, just thought it would be faster. We didn't buy the boat new, maybe the prop was changed. Anyone know which prop should be on it? Thanks.

Baller Ed_Johnson Posted August 20, 2013 Baller Share Posted August 20, 2013 @jedgell...Could you tell us what prop is currently on it ? Link to comment Share on other sites More sharing options...
Baller Kelvin Posted August 20, 2013 Baller Share Posted August 20, 2013 @jedgell, what kind of RPMs are you getting at WOT? I've driven 2 separate CPs (a 2012 and an 2013) and both had WOT RPMs of about 4400 with the top speed in the range you stated. I thought it was a little strange. My understanding is the PCM 5.7L engine is designed to has WOT RPMs of 4800-5200 or so. Link to comment Share on other sites More sharing options...
Baller jedgell Posted August 20, 2013 Author Baller Share Posted August 20, 2013 I'll have to check which prop is on it, in a couple days. @Kelvin - I didn't look at the RPM at WOT, but I'd have to assume it's higher than 4400 since the rpm is higher at 34 mph.

kfennell Posted August 21, 2013 Share Posted August 21, 2013 I will pay attention tomorrow when I am out, I think that is 3-400 more then I normally have at 34. Link to comment Share on other sites More sharing options...
wrecknprogress Posted August 21, 2013 Share Posted August 21, 2013 Mine is a 2013 with a 6.0L. I'm not sure what prop is on it, but that's a little high on RPM's. My top speed is 48 at just over 5k rpm. It only has 40 hrs on it. I feel sure she'll run over 50 once motor loosens up. Link to comment Share on other sites More sharing options...
kfennell Posted August 21, 2013 Share Posted August 21, 2013 Mine revs 3400 at 34 with no skiier and 3700 at 36 with a pro skiier skiing Link to comment Share on other sites More sharing options...
Baller jedgell Posted August 21, 2013 Author Baller Share Posted August 21, 2013 @kfennel. Thanks for checking, that's where I thought it should be. Is yours the 343? That's what ours is. Link to comment Share on other sites More sharing options...
