After raising the motor numbers are:
1000rpm........................4.9mph
2000..............................8.3
3000.............................13.4
4000.............................26.3
4400.............................30.2
5000.............................33.9
6000.............................41.5
4400 is where I wanna cruise as V-Tec kicks in at 4500 and uses a little more fuel...
Still feel motor can go up one more notch cause still getting a little spray...gonna be rainin' this week...can't work, so I'll have time to play w/it ;D./..We'll raise it another notch and if it doesn't blow out on turns and outta the hole, that's where she'll live...

Sounds like she's dialing-in nicely, RAP.
Just curious, where are you getting spray, from the sides while running, a little roostertail in the wake, or somewhere else?

That's great!! . . . . anything above 40 is really honk'in in that boat. What prop did you end up with on the 150?

Thanks, guys...the spray is shooting in a V from the front of the motor's lower unit...prior to raising it was quite a lot of water...now it's just a small stream...I'm almost willing to live w/it, but if raising it one more notch will eliminate the streams and maybe add a little performance without blowin' out, then I gotta at least try ...
The prop remains the frustrating part...these numbers are w/a Mercury Mirage 15 1/2" dia. x 17 pitch...GREAT, but it's a heavy prop and causes lower unit noise(rattlin') at idle speed(trollin') and sloppy feel to shifter...these problems go away with a smaller(lighter) prop....next try is a Honda prop; 14 3/4 x 18...the hope is this one will get the numbers w/out the problems....17 pitch Honda got nowhere near those numbers....
Probably more than you wanted to hear, but there it is...

RAP - not to mention that every notch you move that motor up allows you to operate in skinnier water too.
Sounds like some good numbers.
Hey, speaking of raisin the motor, I finally took both of those 140hp Johnson's off that I lovingly refer to as "the burden" whilst in tandem. I bought that fixed position jackplate I been looking at and hung the better of the two motors on it. The motor is a 25" shaft, so I needed to go 5 inches higher due to my 20" transom.
Here's the jackplate I bought:
P.S. Anybody interested in a 1989 counter-rotating 140hp johnson w/stainless prop that needs a solenoid and possibly a starter for a goooood price. Its already on a pallet and needs YOU to load it on your truck ;D

Yeah, Blue...I'll raise it "to da moon" as long as she BITES...higher the better for several reasons and skinny water is one of 'em...
I thought about a jack-plate like yours, but figgered I'd eliminate all I could get from the transom first...looks like I'm gonna get it...
Got a buddy w/a 23' GW runnin' twin 140 Johnnies...I'll ask him if he's got any interest in your motor...
