The USCG decided to take control of things and put forward a speed limit in place that restricted newly manufactured watercraft from exceeding top speeds of 67 mph.

See the article “Do You Really Need That Much Power?“ Use … As Sea-Doo GTX models have supercharged as well as non-supercharged engines, we should check these models one-by-one.In the case of the GTI 170, there are no official tests available for the Sea-Doo GTX 170’s top speed and acceleration, but considering its predecessor GTX 155’s top speed (55 mph), the GTX 170 will easily reach 56-58 mph.The GTR 230 is the most affordable Sea-Doo performance model, thus it’s one of the most popular as well!

He is going to special order a 9 pitch with some special turbo boost. The RPM does seem a little low, though. Quote; Share this post.

How fast should my boat go Sign in to follow this . It takes over 300 hp to get the 82 out of it.

Since pontoon boats are generally not built for speed, skiing and tubing behind one can be difficult unless you take care to select an engine, weight, and pontoon style that will be conducive to speeds required for skiing and tubing.I scoured the internet for guys who have reported their speeds on forums around the web.

When buying a pontoon boat, one of the major considerations is your top speed. will I gain any speed adding a center tube?For Bob & Bob Dawson. I’ll spare you details but it sucked. Let’s check these models’ performances one-by-one.

I have adjusted the prob and I have performance underskinning that I installed, my top speed with GPS the about 28 or 29 miles per hour wot at 5200 rpm with 1 person. The propeller is a Mercury Revolution 4 (48 – 857024A46 17P). With some models that can reach 0-30 mph in under 2 seconds, you are sure to have a great time even at the Coast Guard’s speed limit.If you wish to test out the speed and acceleration of the different models for yourself, please check out our For more information about available models, you can find specs, pictures, and videos in our  I’m looking at the Yamaha 4 stroke T60 (60hp). What a blast blowing the speed boats by. Much slower and it’s in the water.The boat LEAPS on plane in a couple of boat lengths – but I need to keep the engine trimmed nearly all the way forward (at level, it cavitates terribly; and engine RPM go up with little speed increase) – and I’ve double checked with Bennington to ensure that the engine’s mounted correctly (deep enough).That what a toon is made for Ie enjoyment no speed. These days, pontoons offer everything from built-in wet-bars to wakeboarding towers to underwater lights, and they can go fast.

This is the smaller brother of the RTX-X, as it has a slightly shorter hull and a seat for only 2 riders.It’s one of the highest performance Sea-Doos, so it’s definitely not the beginner’s level!As in the case of many other Sea-Doo models for the 2020 model year, You may be wondering why most of the performance Sea-Doo models can’t exceed the speed of 67 mph?You should know that before 1999, there were no restrictions or rules regarding PWC speeds.

I’m turning over 6000 rpms@Austin – That seems really fast fast for a 90hp. havnt used it yet but am needing a new prop. Any suggestions or is 38 about right?Seems like 38 might be just a hair slower than I’d expect, but I’d doubt 50. Link to post Share on other sites.

Have you tried a different prop with a little less surface area? (65 mph with 2 mph tolerance).From 1999 and onwards, it became necessary for PWC manufacturers to install speed limiter units into the models that would limit the power of the engine.The fastest Jet Ski, Waverunner, and Sea-Doo models can go a lot faster than 67 mph as you may have known by now. Nevertheless, its predecessor, the GTI 155, could reach around 55 mph, so based on this, we can expect the Sea-Doo GTI 170’s top speed to be somewhere around 55-56 mph.You can expect the Sea-Doo GTX’s top speed to be around 55-67mph depending on the model. The length of an outboard is measured from the top of the clamp bracket to the anti-ventilation plate, and motors are offered in four different lengths: S (short, 15 inches), L (long, 20 inches) XL (25 inches) and XXL (30 inches). Acceleration plays a key factor when it comes to your Sea-Doo’s level of fun! Joe Carozzoni offered a suggestion - When builders list the engine (.e.g CID/HP) and propeller size/pitch - it's not much help unless they give a transmission ratio.

not looking for crazy speed, or pulling anything, live on a river.

All speeds recorded with GPS, and except where listed, with a light to medium load.Your initial response is probably “the faster, the better” but in reality you likely don’t need to go as fast as you think.

With WOT @ 6,000RPMs I am only getting 38mph (by GPS).

I thought "Yea right"!! The new hull of the GTR 230 offers 42.5 gallons storage capacity and a convenient seat for 3 riders.The other flagship performance PWC in Sea-Doo’s fleet is Powered with the same engine as the RTX-X 300, the Sea-Doo RXP-X can go as fast as 67 mph.
