We were on bay. My Dyno was the bay. But we had a Dyno hydraulic pump. Not sure if it's exactly accurate correct horsepower but it's close and good to pretest motor before launching. I had one come off shaft went to 10000000 rpm lol .
@@danosburn80 They did not come out black and sooty. DVA tests showed the ignition was in spec. But you are correct...it was not stretching its leg and clearing the fuel. Unfortunately, the customer did not want us to pursue as to why this was happening.
dude a 140 merc is rated at the powerhead yea, but this model is really a prop rated 115hp so around 125hp at the powerhead. no way it looses 18% through the driveshaft. in reality its like 5-8%. the 140 was famously overrated even for powerhead numbers.
I love that dyno!
This was cool!!!
Great content, the only of its kind on TH-cam! Your clients are lucky to get such proper testing done!
@@andronclock1 Thank you!!

I have torn out a coupler or two as well :P
that 5 cyl force sounded a bit rich to me. what do the plugs look like?

@TheMarineDoctor rich is safer, and if it's not fouling plugs to bad send it.

@@ct1762 Fair enough. I stand corrected. Thank you for pointing it out.
