    Mercury 3.0 EST no spark

    I'm using cool fuel, but again you can use anything that will produce more then 37 psi, and then the Reg will lower it to 37 psi

    vapor separator tank removal and upgrade

    I went to MEFI 3 due to better fuel tuning and there were more spares out there. MEFI 1 has very little adjustment for tuning fuel supply, and was the driver due to more HP build. Also changed from V-belt to serpentine but that has nothing to do with current build other then easier There is...

    vapor separator tank removal and upgrade

    My original motor was a VST setup like yours, 415 HP with VST. During repower I changed to cool fuel and now have 530 HP. The mechanical pump was removed, cool fuel installed, fuel rail was modified so HP fuel came in from cool fuel pump and entered one side of the rail to feed injectors. The...

    vapor separator tank removal and upgrade

    Howdy 502 VST should mean you have a belt driven mechanical low pressure fuel pump running off the Bravo raw water pump. Then pumps to VST Post your serial number so we know exactly what your starting with. I take you want to remove everything and change to something like cool fuel, or...

    Volvo Penta KAD 300 power steering issue

    Will take me some looking to know exactly how it functions, but my guess is its similar to other types. The wheel is moved which applies pressure on one side or the other of a valve back by the steering cylinder. Applying pressure opens the valve which sends high pressure fluid from the...

    Volvo Penta KAD 300 power steering issue

    There should not be a power steering pump. The Seastar/Teleflex steering is fully self contained and does not have a pump. When the wheel is turned its similar to a bottle jack where a small pump causes the bottle jack to lift. Where as the wheel is the small pump, moving the rudder cylinder...
