I too hoping for big things on the 5 blade, but jeff had so so results on his 210 . if you can change the sensitivity can you tell me how, we did on our pp but cannot find any information on the linc 2.0 manual. thanks

Did another session with the 2315. Pretty much same results as last time, although the rpms seemed to be about 100 more...we we're running right around 4600 this time (this is at 24 mph, factory ballast + 2200 extra ballast + 3 people). I'm guessing this was about 500 pounds more than my first test, which is maybe the reason for the extra 100 rpms.

With just factory ballast + 3 people @ 22 mph we were right around 3900 rpm.

I've got the 5 blade on now, so I'll get some figures and comments on that the next time I get out.

Top speed with this prop was 37 at 5600 rpm. Again, not something you'd want to do for more than a few seconds, imo.

I finally had my G23 out on the water this past week. Mine has the XS550 motor with the 4-blade 2247 prop. This motor is amazing, sooo much quieter than the 409 and gets the boat up on plane and moving very fast.

I saw full speed at 5400RPM of 65.4 kph (40.64 mph).

Still breaking it in so I only tested the ballast and getting up to speed with it briefly so not sure what the wake rpms would have been with ballast, however, I did learn that at full factory ballast if you stop too fast you get a tidal wave come in the back of the boat .... This was quite surprising ... I was very pleased with how fast the water was dispersed and drained away though!

I will get more info on the rpms at surf / wake speeds in the next few weeks.

found out about the tidal wake too, if you turn the wheel the same time you pull the gas back the big wake will not come in,and helps push the boat around before you put it back in gear to pick up the down rider.

I soaked a few folks in the stadium seat last week. They need a flip up plate, similar to the NASCAR roof flaps, that flips up with sudden deceleration.

**robertsmcfarland** · 08-20-2012, 06:29 PM

we thought the same thing, keep it a secret and soak the ones who act up!

Had a chance to try out the 5 blade yesterday. Pretty disappointed with the results. Its whole shot was fairly close to that of the 2315 from a timing perspective (maybe a bit worse), however, it vibrated the boat a ton from about 14-20 mph. Once at about 20 mph the vibration went away, but then it ran at about 5100 rpm while at 24 mph. It did not vibrate when there was no weight in the boat, so it's not just a defective prop. Right now it seems as though the 2315 is the prop to go with (if you find that the stock, 2313, is not enough).

thanks, well that ends that discussion.

Great information but I am a little surprised that the 550 HP doesn't pull a larger prop to yield a higher top speed and still have a hole shot with ballast. I know these are not speed boats but that baby must be turning some rev's on a leisure 32-34 mph lake cruise?

How is your fuel consumption on this motor? Some have speculated it to be higher than the 450 but sometimes the larger hp motors don't have to work near as hard and use less fuel.

Thanks for the information!

I am not 100% sure on fuel consumption yet as it is still being broken in, so it will only get better. So far I have run about 6 hrs for about 40 gallons and that was cruising and pulling a little with weight. I dont find it that bad and my suspicion is that the larger motor would be better on gas as it is working a lot less to get up and out of the water.

I think the reason for the reduced speed on these boats is just how much is in the water, the front of the hull dips down, so even when you are "planing", you are still pushing a lot of water. When you set the "Back To Dock" it sets the speed at about 45 km/hr for the cruise home, so I assume that is what they recommend and is around 4000 RPMs.

45kph is only 28mph. That as a maximum sustained cruise (4000rpm) with the 550 engine almost scared me off of considering this boat as an option. I tested one yesterday with the 550 and with empty ballast, 5 adults , one kid it ran at 32mph at 4K.

Could be the elevation difference. We run ours in British Columbia up in the mountains. Where did you test drive yours?

Minnesota - lake elevation 930ft. Nice call. Despite my previous comment I would trade 5 mph at cruise for proximity to Whistler any day.
