Hard to beat displacement no matter what (natuarally aspirated) engine ....... I rather play with set up than how to squeeze the last breath from a mouse vs a issue with a Rat that has too much thump .............

We will see what happens....I drove 2900 miles last Oct in two weekends between Flint and P.A time trials and got screwed at both....between flints hurricane winds and the sensor problem in P.A I was burnt out.

I have a aromarine sprint cat with a zenoha stock 260. I'm thinking of purchasing this mod for it. Anyone have any experience with it? Are my performance gains going to be worth the money? And is there anything else out there comparable?

Ask a question about this product
This is our new CNC machined Zenoah ''Bolt-on'' GZ 29 28.5 cccc water cooled cylinder kit . This kit will give you the Monster torque for the large scale boat or a Large powerful racing upgrade. This kit is for you. Comes with everything you need to bolt on 6.8 true H. P. and 3 lb's of torque . If you like to upgrade your Zenoah or RCMK without paying big money you don't have to.
NOTE: That we make the cooling cap specific for the 28.5 cc cyl for proper cooling that you need. This is not a cooling cap made out of a 26cc which will not give the proper cooling you need for the high horsepower. This cap will also bolt right on the 26cc motor also for a lot of extra cooling.
Here is what you get:
-Transfer ports are modified on a CNC machine.
-Cyl base cut so can use stock gasket to increase compression
-Intake & Exhaust port modified on a CNC machine.
-Our CNC machine 20 gram 36 mm Pro-mod piston.
-Cyl is dressed by hand to insure that everything is blended in.
CNC Machined ''GMM Racing'' Cooling cap.
You don't have to be an engine builder to install this kit. Just unbolt your cyl and remove piston and parts and install the kit. That simple.This will increase apox 15 mph over stock.
As always we stand behind all of products 100%.
Please check our prices, also you will see there is no CNC machined kit like this on the market.

Usually, just show up. Yes, it's basically that simple. Have a current sanctioning body membership card with you then most of the time it will cost you a few dollars to make runs. The record trials are listed on the IMPBA website as probably the closest one will be under them.
I go to the Flint record trials as that's where I first met Wally. I haven't ran a boat yet at the trials but have one right now that has a good shot at the oval and 2-lap record for its class.

fuel crazy= do you have to be real fast to attend them? Pretty new to this, but my boats are pretty fast. Have gone over 75mph with a Sprintcat with prop modded myself.
