Tige 2-1 Transmission Test

[Germaine Marine]

We did some testing this weekend at Pine View which is nestled at around 6k feet and the results were outstanding.

We ran the Rzx2 line with both the 400 and 440. All I can say is wow. Both motors had no trouble planing out the boats with full ballast at wakeboard speed (roughly 17 seconds). They also hummed at a comfortable 3400rpm while surfing at around 11.6mph. Everyone was pretty shocked and excited about the results. Both motors were ran with a 17/14/.105 cup prop. Again plenty on the bottom, and with some cup tweak will run 37-38mph.

For those lucky enough to be at sea level, this drivetrain 400/440 should be able to both cruise at 40 and have enough bottom to haul around big big weight. The bigger diameter prop options are really changing the game.... again it was shocking.

What does this all mean? The 400 in my opinion is a legitimate option even at the high altitudes and a great way to save some money on a custom ordered boat.

That's really good news. Is 2018 the first year for the 2:1? Most of the other brands big boats are doing at least the 440 and most are coming standard with the SC motor. Here in Utah, anyways. I've always felt the 440 was a waste of an engine as the HP and torque curves are pretty much the same up to almost 4k before the 440 pulls ahead. If it will surf at 3400 you're wasting money buying a 440. At least I would be. We run empty ballast for everything else.

FYI: Pineview is just under 5000' and really only there for the party scene. Any boat will work just as good as the next if you're only there to drink. If you really want to test your boats loaded surf/wake abilities, head to Jordanelle. At over 6000' I think you'll see a difference. After owning 2 boats that I have not test drove on local lakes, my next one for sure will be purchased locally and tested at Jordanelle. If it will pass that test then I can be much more confident that it will be a great boat for my family.

1k more feet shouldn't make any difference with the amount we had left on the bottom...

[chpthril]

Bout 3% difference in HP.

We felt confident testing it at 5k feet.. whether that place is a part scene or not didnt have an affect on what we did which was load them up and surf for hours and hours in all types of water. Needless to say, the boats ran insane with plenty left on the bottom, enough to where we would be doing a less aggressive pitch prop for the avg joe with the 400 and 440 even at that elevation. Mike says its a 3% reduction in HP, who knows about the Torque. All things considered a 63HP loss vs a 53Hp loss I dont think will be that noticeable with what we had left on the bottom prop wise. My guess is you hardly feel it if at all until in the peak Hp range.

I know what we had left with the 400 fully weighted at wakeboard speed at 5K and it was ALOT given it was pushing a big heavy RZX. Again not worried.

[Germaine Marine]

I think reaching big top speeds will be an issue. You are going to see 33-35 and thats about it.

[UNSTUCK]

So in Utah, going with a 400 in an rzx2 won't be a problem?

If that's really the case then Tige has really passed the competition here. MB won't bring a boat here with less than a 440. Last time I looked all the showroom Superas had 575's. Moombas run 400's here but not sure how well they do. I don't care to look at any other boats.

Nice work.

Is the 2:1 a Tige product?

what props are coming standard on rzx 2018 models?

Standard prop for the 2:1 is the 16.5x16.75
Higher elevation prop for the 2:1 is the 16x13

Working with Tige to offer the 17x14 as an option from the factory.

No, a few Mfg have dabbled in the 2:1 realm for a while now , most notably Nautique because they actually squared it away. The difference between some other makers then and the trend now is the strut angle allowing for a bigger diameter wheel underneath. The thinking is different, and its for the better. I suspect from what I am hearing, that 18-20 inch props with less pitch are in the near future. The reasoning? the 2-1 can turn them dependent on pitch which essentially gives you this monster wide power band. The big diameter drops Rpm, increases bite without losing a ton on the top usually seen in smaller props when pitched for more hole shot. Its a win win. When pitched/cupped correctly the ability to run big weight and still push into the 40s on top will be a reality. Heck its almost if not there now with a 17 inch.

I think we noticed some wake issues with the big prop this weekend at wakeboard speed. Whether that can be tweaked via ballast or plates remains to be seen. I wasnt driving or in the boat for the wakeboard section but I did hear it from some riders. It produced a more prominent lip. The problem is this is all so new......

Piggy backing off what Adam said....
The 16.5/16.75 prop is just pitched way wrong. I dont know how they settled on that or who did the testing but its *** backwards. While the 16/13 is a stronger option because its pitched so drastically different, I see no reason to go down in diameter from the factory number. For example a 16.5X13 would be a better option at altitude if the 17 didnt fit, but it does. As long as no one gets prop burn which we would have found out last weekend then I see no benefit to going smaller diameter wise. Pitch it correctly for the altitude and cup it correctly to offset when the help on top comes and you should have a prop that outperforms anything in the smaller diameter realm.

A sea level 400 with the 2:1 with a 17/15 should be amazing. You are talking about a setup that will have enough to push the Rzx around with PNP and Lead, surf at 3400RPM and still do 38MPH on top if not more.

Im basing this off of the 400, 2:1 at 5K feet being able to push the boat full of ballast with ease into the mid 20s, surf at 3500-3600RPm and still squeak out 34MPH

No lead or PNP, a change in pitch and I think you are surfing in the 3200 RPM range, wakeboarding fine and hauling butt around the lake over 40......

Ill be running 3 different props this summer to give everyone an idea, should be killer!

The 440 is still the best option I think when it comes to power etc. The 400 being detuned is going to fall behind the 440 in performance no doubt. I guess it just depends what is most important to you. I dont need to have a 40MPH boat around the lake, although I think I might still get that with the 400 correctly propped. As long as my boat can push big weight, can wakeboard and can still motor from spot to spot empty in the 35-37MPH range I will be ecstatic.

I think you are going to see a lot of MFG going to the 2-1. If the angles are right and the clearance can be achieved it makes absolutely no sense not to with the non SC motors...

[CarFanatic]

the 400 and 440 are the same motors correct? its all just ECU tuning I believe.

[IDBoating]

That is exactly what a boat manufacturer told me: The 400 and 440 are exactly the same hardware, your ~$6K buys nothing but different curves in the firmware.

Might be nice if a little cottage industry popped up to give these engines the same aftermarket "chipping" options that the diesel truck engine guys enjoy....
