So I head out tonight to see if my water pressure issues have been solved since I replaced the water pump. Put in at the local ramp and it's calm enough so I idle to the chute leading to the channel. Drop the hammer and blast out to the channel where I encounter rolling white caps. Tried to find some calmer water to no avail when I decide to head down stream. Here comes a barge that makes the white caps look like ripples. I just can't win. On a good note though. I gained 2 more psi with the new water pump. The most I ever saw at any rpm was about 18 though. Held enough water pressure up to 5500 RPM which is an improvement but I couldn't open it all the way up under those conditions. Hopefully I can get some clean water soon. I suspect there might be a small issue with my set-up but I won't elaborate (too emberrassing) . If it is in the set-up you can be rest assured I'll blame my brother!
