Yes

I've put 74" three bade Ngh and 76" three blade h on these engine with good results.
If it's not a strong engine you can get buy with a long two blade.

Run a full length three blade r series Sensenich 80/82" . You should have the room for that on that wide of a hull unless the cage was built small. If 80 is as long as you can go then no worries you will be fine. You will want to run your engine @ wot between 3800 to 4000 max. This will allow y...

No worries I have been spread thin to say the least and trying to boot strap this thing with out big money and fight vendors has been tough! That being said, I am climbing out and will be in strong position in the next few weeks. There is enough out there for everyone and I can't fill all the orders...

I been buried in work up to my neck in alligators. I'm still kicking. I haven't been trying to stir up to much extra work till I get caught up. Thanks.

I know deck height will not permit The larger diameter propeller but there will be a gain in thrust going from the current 76 inch diameter to 80 or 82. Just a thought.

I guessed it Within 5 pounds. I said it felt like a small block now I see it's blowing like one that is incredible! If we can get this combination to blow 1252 1300 pounds of thrust that will be a killer combination. Not taking anything away from it now but I believe this Can be a reality. What impr...

pmed ya.

i have a adapter plate that makes it bolt right up.

72 q series is a dead on prop combo for the gpu. the ngh has a little more on top end but the gpu has good tq and likes the q off the bottom.

sweet!!!!
you ant seen the size of the turbo on my ecotec yet

i have a feelng will be seeing even faster runs out of the zilla in the near future..

2.38 to 2.55 ratio would be a good fit with a three blade r series. diameter will depend on hull width and cage size. hard to miss with this combo.

the push and performance of this boat feels as good as any good sbc.. if you didnt know what was behind you you would not know the difference ! the thrust to weight ratio is killer and well the gas milage speaks for itself .. i had ignored this engine for a while. but it has my attention now! i woul...

Dave and andrew took the time to come buy my shop today to visit . They are working very hard to get the company back into shape and sounds like they have already addressed key issues . I know how hard it is to get things going so i can relate to what there going through.. we will be seeing more of ...

This ecotec has got my gears turning!! I would like to put just a little more squeeze on the engine and go a little lighter than russ has it and it might be a little lake side contender.. its certainly breaking a couple rules already so it has my attention..

I want one of those so bad I can't stand it...
Dave just has to sell a couple more oxes then ill be there. Quite a combo for sure!

Other than not dragging its tail that would be nice for one of these engines. Turbo normalize this boys!

Hey Dan, if you could eliminate the 'just off idle' serious VIBE, my hats off to you. I enjoy the confidence of the Rotator strength, but MAN, I can watch the wave of vibration as I accelerate up to full song. Russ and I have formed a friendship, and we represent two ends of the ECOtec scale. Mine ...

After talking to Rus about his today. I am very impressed! The power and mileage is crazy!! I'm going to make his gear box noise go away and then look into this project further. I don't see why this wont be a viable airboat power platform. Just wait for the next big gas spike.. In talking with him t...

I'm liking what I see! I think this will take off.
I will build a box for these engines. Looks like there more than getting the job done!

We could exsperament with a trim tab motor to actuate..
