How is the cooling when running hard ? Does it stay around 80 degrees . Also what model bowman heat exchanger is that your using ? Thanks …. Cool Boat 👍
Cooling is good. There is a 75 degrees celcius thermostat mounted. When running hard with fully loaded boat and a funtube behind, the temperature is about 90 degrees celcius at the engine outlet (hottest point). The heat exchanger is a used bowman industrial hydraulic oil/water cooler. Model i dont know. The coolant ports are 1 1/2 inch pipe threath.
Superb - sounds great cruising too ☺
What year, make, and model is this boat, actually?
what speed are you getting at what RPMs looks awesome
75 km/h at 5000 rpm. I like it around 4000rpm speed about 60/65 km/h
@@leonvanzon wow that's awesome

@@leonvanzon thanks for that . So you have replaced the standard 80 degree thermostat for a 75 ?
@@adamm7513 yes i have
Which sterndrive do you have ?
Volvo penta aq280 1.61 gear ratio. (V8)
What kind propeler you have
15x21 1.61 gear ratio
@@leonvanzon Is it a reduction ratio or an overdrive ratio? Like, if you put in a 2.35, would the boat be slower or faster?
@@Drunken_Hamster
It will be slower then. Its a reduction
@@leonvanzon Ah, so if there aren't any gearsets lower than 1.61, the only ways to make it faster would be more prop and/or more RPM.
@@Drunken_Hamster yes
