Who lightened it? Thanks Shmity

Mitch Miller at M&M marine has sent I am sure. Just picked up two of them for ET1107 build. (530) 661-0074

ET mentioned the 9/17, I am starting with a 10/16. Will let you know when I get it on the water.

Sure are.

Best bottom end. Who is running similar size motor or same setup and what impeller are you running? Impros said 10/16 E75. What cone do you have? What is the nozzle bored to? Thanks

Yes, I do have some I could send out. PM me. Shmity

All engines are ran on a dyno after being built. We haven't ran on the dyno with BNs but after tuning with the Tillotson and switching we have found better bottom end punch and working on a different pump setup. Durability...around 150hrs for first inspection. Depending on how "hot" you ran...

Still moving forward. I am not sure why someone would write DOA. Update...tested BNs and found more bottom end punch. Allowed a better pump setup. We have a distributor in Australia committed to purchase a few motors for this coming race season. Building another version with rated HP of...

Is there something specific you would like to see? besides under the hood...

In the middle of updating the starting system. Once this is complete we should have a ballpark price. Thanks

Not me riding. But need to keep an eye on the instruments to see whats going on with the engine. Water Temperature, rpm, bearing temperature, exhaust temperature...etc. Need to make sure it will be bulletproof. You won't be impressed looking under the hood with all the thermocouples and...

Another video. Playing with Props.

Ok...Let me start off by saying I can move anywhere in the Pacific time zone. So where can I move where the weather is perfect, the water is clear..and 2strokes are accepted. Good schools. The ability to live on the water or within 5 minutes. Any suggestions besides California...no offense.

It will workbon any 2008 and up nozzle.

A rotary is not a true 4-stroke with a piston and intake valves, but one difference between a rotary and a 2-stroke is that with a 2-stroke there are unburnt hydrocarbons passing from the intake port through the exhaust port and out the pipe. Unburnt oil and gas out the exhaust (Except in the...

Yes, you are correct. As mentioned earlier we have already been in contact with both CARB and EPA about this process.

Pricing...we are not ready to announce pricing. We have a target and the target is to compete with other manufacturers of engines. Dasa for example produces engines starting at $6,000 all the way up to $8,500. Keep in mind that there engines do not include couplers, ignition system, fuel...

Rotron 300cc castings come from the same foundry we get our castings. Rotron advertises their 600cc engine having 66hp. This is rated for continuous HP in an aerospace application. There are design differences between their engine and ours but the castings for the rotor are the same. The...

The motor is modular but would require a new crank. Theoretically we can make a 3 or 4 rotary but at some point the PTO will break. "Charge Air Cooled" meaning the air coming into the outer two intake tubes pass through the crank bearing, then through the inside of the rotor, and then into the...

The Torque curve is impressively flat. Almost a straight line from 3500-11,000RPM. Peak power starts to come on just over 7,500rpm and holds up to 9,000-9,500RPM. There isn't an oil sump like a Mazda. In order to align the PTO of the engine with the drive shaft there just isn't enough room...
