guys, what would cause no water pressure, gauage shows 0. have new water pumps and motors are not running hot, motors are 525 hawks. also gaffrig gauges are new. thankx scott

Hey another LA boater, welcome!

Im sure you have checked all the basic stuff, senders, wires, gauges, grounds.

Are you running the boat on the hose in the driveway? Some pressure gauges wont register when running on the hose. On my Fountain if I use the ear muffs it will show no pressure. If I use the flush system it just barely shows some pressure.

Where do you boat?

I added 1 this year and had to play with it a little to get it to work. 1st I had overtightened the compression fittings which will crimp the tubing. They need only to be snugged up. Then I had to blow the tube clear from the guage back. It only take a little rust/ect. to clog the tube. Also mine will only show about 1 pound on the hose. Good luck

RON, WE RUN ON THE OUACHITA RIVER IN MONROE LA, WHICH IS NORTH OF BATON ROUGE ABOUT 3 HOURS. I THINK THAT THERE IS RUST OR SOMETHING IN THE TUBE THAT RUNS TO THE GUAGE. THANKX SCOTT.

Make sure its even hooked up....sometimes these engine guys drop motors in and forget to get down there and hook it up.

Scott,

If the engine is pumping plenty of water and your temps are not increasing, chances are you have rust or other debris in the pressure line. Are you plumbed off the boss just above the oil pan rail? If so, as sediment etc settles in the water galleys, the small line for water pressure will clog. Easiest fix is to pull the line from your dash and from the engine and either force water or air into the line to clean it out. This may become a regular necessity I have triples and usually 1 out of 3 aren't working but the innercoolers are pumping well and the exhaust is flowing fine.

Hope it's OK.

Steve

If it is a continual problem, why not put the pickup on the intake?? That's where mine is located and it has yet to clog---and I boat in the Ohio RIver!!!HAHAHAHA

I get 1-2 lbs ont he hose as well.

What's up CFD12??? River Wed???

My water pressure lines would plug-up with sand every weekend.

Low water pick-ups were added when we installed Whipplechargers

I removed the lines from the stock location, about 1" above the oil pan on the side of the motor.

I installed pet-cocks in that location.

I reroughted the lines to a T fitting, along with the water tempature sending unit @ the front of the water crossover.

45 lbs at cruse and no more problems.

Steve

You have 45 lbs of water pressure. That is WAY HIGH. Max should be less than 30. I think it could have something to do where it's mounted. Sounds like you are measuring the pressure before it enters the engine.

guy, started both motors after i cleaned both pick-up tubes, and still the gauge reads 0 . the pick-up tubes come out of the blocks right above the oil pan. should the location matter? thankx scott.
