I wouldn't run that engine for more than a minute or 2 with no stats in it. And yes without the stats you will have virtually no water pressure in the engine. The pisser is fed directly off the main feed coming from the lower unit, so it will get water quickly. And I'm not sure which engine you have there, but if it has a spring loaded bypass on it I would replace the poppit and spring in it as well. As for the water pressure guage, if it is hooked up down on the starboard side below the powerhead it will get fed cool water as that is also fed right off the main feed supply.

Thanks for taking the time TF. She's an 01, new powerhead in 03. My water gauge pipe comes off the rear center, from what I'm guessing is part of the exhaust?. I think I do have the crossover you mentioned, mounted on top of motor, pipes leading to both cylinder banks. I'll clean out and check absolutely everything for flow before next run, install pump OH kit, and check out that crossover unit too. Thanks for your info, now I understand why I only had a little flow with no stats. On the first run (with stats) I let it idle mostly and kept checking the block for temp by hand until it was uncomfortably hot. I didn't get a hot alarm, but I wasn't happy that warm water wasn't appearing in any amount, and showing no water pressure, so I shut it down. Am I correct thinking that water should flow from the ports either side of the peehole when the stats open? If so, I shoulda had a ton with no stats in?

I'd be grateful for any other pointers you have on this baby. Its a lot more complicated than my old merc 115...just had to drown it in gas and oil and press go!
