Yes it is the same Hydro that I sent you a while back, The Miss Merion Bluegrass.sdiesel":1cnap29e said:is that the same hydro as earlier, one you sent me some years ago, the miss dairy?
and how did you pre heat the coolant?
do you have figures on the dry weight of that engine?
i recall the fuel management on that engine was tops with no surging or slosh on pretty rough waters
We regulated the coolant temp with 1/4" to 1/2" jets in the water line coming from the rudder pickup.
The water first split to the gearbox and oil cooler then to the engine and out the back of the sponsons.
The gear box and engine oil heat exchanger offered a little preheat.
Water pressure peaks around 25 psi.
We once made the mistake of restricting the water with jets at the exit point. The pressure peaked at over 100 psi and ballooned the engine oil heat exchanger.
Never weighed the engine but I suspect it was near 800 lbs.
Kirk built a special heavy duty engine stand just for that engine.
The 26 gallon fuel tank is filled with wiffle balls and the fuel pickup is in an open top box with one way flappers in the sides so fuel can go to the pickup but not out of the box away from the pickup.
As far as lakes in WA state we ran Spanaway lake, Black lake, lake Chelan, lake Coeur d'Alene and several places along the Columbia river.
Other APBA events in WA are help in Silver lake, Angel lake and lake Lawrence.
