And when I said not over 3 grand...pretty sure not, but additionally not sure tach is reading properly...it's a new teleflex...do you know for sure which setting it should be on

It should be set for 12 pole which should be 5 or 6 on your tach. Those valves always leak a little it seems like. If the diverter valve is in wrong it can cause overheating problems as it will work in reverse. the heads should be torqued to 18-20 foot pounds starting in the center and working outward in a circuliar pattern. They are known to leak compression into the cooling system but not water into the cylinders.

Thanks, Ferm...FINALLY I can set the freakin' tach!!...there IS joy in Mudville!!...and for the torque settings and pattern...I looked at them all around a couple of times and see no sign of leaking...should I torque anyway?...and I think I'll pull that diverter valve just to check it out...found sand in on t'stat housing today...that valve looks like it could hold some too...

She's pissin' better on the hose

But pisser STOPS and it runs hot at speed..don't know if you saw the other post about my local tech saying motor is mounted too hi and not getting enough water when on plane at speed...makes sense, although I REELY wanted it as high as I could get it, I think he's right...gonna try it tomorrow...

For an offshore boat I prefer to mount the engine a bit on the low side so the prop stays dug in when I trim it up to hold teh bow up in the snotty stuff. And with the OMC lower units they will suck air if you mount them just a bit to high, learned that one the hard way.

Apparently I'm in the process of learning it as well...I was really hopeful of getting the extra top end and EFFICIENCY that comes w/having the foot outta the water...but we'll find out today...

Yeah, I'm guilty as hell on that one...you had it right the 1st time...

Congrats on the wet test. My puter done died. I just got the laptop fired up. I saw the other thread. Sits high in the water. If the bottom is rough it could cause a bit of turbulence. I would love to see a picture of the stern with neutral trim kinda rifling the cav plate or the keel. Too high by 3/4" ? Which mount hole did you go with? Hot rod..
