You know...the last time I was down there I saw two guys plodding along the side of the road in water skis and they had no arms!!...now I know!!:laugh:

my v20 is powered by a 1990 225 yamaha hiding under a 1987 150 cowling.:sly: It really rips. My best speed was 53 mph by the gps.

Ahhhh a sleeper.:zip:

yea its a real mutt motor. I had a fully dressed 225 powerhead that I rebuilt. I then dropped it on a 150 that was missing a powerhead. Everything bolted right up! Even the serial number on the clamp bracket is for the 150

That's ok, I have a 1986 150 yamaha hiding under an 86 225 V6 special cowling. maybe we should keep our respective cowlings and trade motor for sake of accuracy!

Building a Vortec V-6 for the old V-20 now. BHP was 190 but we'll see after all the machine work is done. :sly: My goal is to pass some friends running '31 Cape Horns!

What type and size is your prop?

I am currently running a mercury laser 2 prop with 19" of pitch and the vent plugs removed. trimmed up I get around 5600 rpms.

Original 470 Mecruiser seems to be plenty of power for me. :party:

I have read threads were guys are posting speeds of up to 45 mph. I have a 93 Yahmaha 150, original motor with boat. Under good conditions what do you think a reasonable top speed is? It seems to cruise nice at about 27 mph at 4500 rpm.
