water flow from heads on 135hp evinrude crossflow

[THEFERMANATOR]

It may take 20-30 seconds for the heads to fill with water running on a hose.

Yea ferm the motor was running for over a minute when i removed the hoses to the thermostat. I would think the flow out of the heads would be constant and not pulse.

The water will pulse out of the heads. The water pump impeller pulses the water out as the impellers go past the outlet, so your not going to get teh smoothest of water flow with no pressure on the system.

Kracker what year is the old cross flow rude you got. I have an old 83 140 Johnson bubble back that never put out water right til I changed the thermostats and housing. After that it spit water hard, matter of fact had I not bought this I/o v20 I was gonna hang it on something else but it's been sitting around useless on the old boat right now.

Yea i just changed out the thermostat and all the guts. Guess with the exaust hosing not filled with water and lower water pressure from well water is causing it.
