Re: radiator distance from prop
my recommendation before you start moving things around, call Turnkey and ask details. that is a great group of folks. as stated LS and Ecotec motors that run on modern ECUs and EFI run 180-210 easily without issue. doesnt matter is its modded or not... if the ecu is controlling temps then you will ...

Re: radiator distance from prop
Honestly 195F is a good number if you ask me! Radiator is where it is supposed to be. I dont like motors that run too cool because that just creates condensation potential in the oil side.
I'm bias a bit though... I have an e-stat that maintains about 200F-210F running temps.

Re: 502 power VS torque
What I have found through many discussions is that it isn't really the large prop vs small prop... its actually air flow to the prop. Larger props move the location of grabbed air further way from all the rigging and crap that can restrict flow from getting to the prop and essentially loading the bl...

Re: 502 power VS torque
according to the dyno sheet referenced you are still climbing in HP even out to 6300 so you are leaving some power and therefore thrust on the table... but the difference since the sheet stops at 6300 is only 25HP+/- there may be more past that... cant tell unless it was dyno'd out there. Should the...

Re: 502 power VS torque
I have read every post... this is all hilarious! Here is how you solve the problem... 1. Get a gearbox that puts the prop at peak efficiency when the motor is at peak torque... measure the thrust (good luck finding that box bc those who made it are after your money not after giving you a boat that c...

Re: How are the Eco Techs holding up
Long story short, my predicament is my fault, not an issue with the motors. Got rain water into the intake tract during a bad down poor and cut rings on one motor. Believe got moisture into the MAF wiring plug and it shorted the ECU so bad ECU fried the second motor. OneBFC is correct as I had my ne...

Re: Question on max engine rpm with reduction belt?
Reductions are meant to get the motor into Peak HP Range... Torque means jack shit without RPM. HP is Thrust... the trick is to get the prop in its most efficient sweet spot when HP is peak. In short, if only torque mattered everyone would be running direct drives and turning props at 3000 rpm becau...

Re: Question on max engine rpm with reduction belt?
2500 X 2.3 = 5750 but target 5200-5300 on the motor as the prop will gain 200+/- rpm on the water.
Also what is your engine curve and where does it hit peak HP. That really dictates the target rpm.

Re: Ecotec motors
I've had engine issues or I'd say come look. I have a 1.4L on a 12x7.5 boat. My issue is in the electronics which lead to mechanical failure. They can be a pain but when they are tuned and running good it's a joy

Re: Ecotec motors
My boat is 12x7.5 .125 bottom/transom, .100 sides, and .100 for the decking and rake .125 is usually standard thickness for aluminum boats. .190 is used on ice boats and work boats from what I have seen in TX and LA.
