Wamiltons Trim....

[Superjetjim]

Need a sanity check if I could please:

Anyone know if you can use the fitting shown below (on the other side of the pump housing) as a cooling line? - the one on the other side goes the other way, if I'm not mistaken the one shown in the picture below is a bildge drain line isn't it? - the fitting on the other side aims into the water flow and I think is normally used as the 'pisser' on some other ski this rear housing is made for - surely this fitting is in the compression area so should have loads of pressure for cooling.



Can anyone confirm or offer any thoughts?

Thanks.

PS - reason for using this is I've had to chop the OEM pump outlet off top make way for the steering cable at full 'up trim' and I've tapped/using the other side of the pump for dual cooling.

nope. cooling line has to be on the stator, not the nozzle.

am i right?

Yes, needs to be on the low pressure side (stator section), just plug it and relocate the fitting.

Oh bug3er - I hope not... Anyone?:bigeyes:

You can add a cooling line anywhere you want behind the impeller. The stock locations are good locations for higher pressures, but anywhere in the back half of the pump will develop high enough pressure with some throttle. The only real problem is finding a place thick enough to drill and tap. When you figure out where you want to add the line, just make sure it is perpindicular to the inside wall or facing towards the impeller.

Thanks - that what I thought too - agree it must be pointing at the flow to scoop up the flow of water (opposite direction to the siphonic bilge line) - I thought the compression zone (as the rear pump housing narrows) would have higher pressures than by the the vanes (stock location) :dunno:

nah.pressure is higher at the vein section because the water is being flung outwards(radially) by the prop.once past the veins,it drops a little.

 

[meatball]

why didnt you rotate the vein section so the cooling bosses are on the bottom?

 

[THRUST]

you actually want to rotate it 180 so that the cooling bosses ar at the top of the pump so you steering cable wont hit the cooling boss . then you will have dual cooling and no interference.

Already hacked it now....at:
