I think the prop that came with the boat was what was always used on it. He gave me the original prop (which was the same [14 1/4 X 17]. This prop was an aluminum cast prop. He bought the same prop in a SS Honda - that's what's on the boat.
I will take off the cowl and air silencer and see what the throttle plates are doing as I move the throttle lever.
Keep those ideas coming in - I really appreciate them.

That 55 sounds more like what that rig oughtta be doin'...if the throttle lever is being stopped by the console, that should be checked out , too...if the budget will allow for trim-tabs, sounds like you need 'em... ;)...and I think that cavitation plate should be just above the bottom of the boat...you may have dropped it down too far...ya wanna get it as high as it'll go and still BITE...too high, and it'll "BLOW-OUT"(prop comes outta the water) on turns...

Keep postin' and let us know what's goin' on... 8)...

I removed the cowl from the motor. I see where the throttle plate is - near the top rear of the engine. Looks like I have to remove a lot of stuff to see inside the throttle plate body. Is this true? Going fishing tomorrow - going to move the motor up 1". I'll let you know what that does.

HEY JACKMAN!!!!

IT LOOKS TO ME THAT 225 HP IS TO MUCH FOR OUR BOATS, IF YOU RUN IT WIDE OPEN THE HULL WILL COME COMPLETE OUT OF THE WATER AND IT WILL PROBABLY RUN SIDEWAYS. I'VE GOT I/O 4.3 MERC (175HP) AND RIGTH SS PROP AND I DO 32-35 MPH.

NOW, YOU DON'T HAVE TO RUN IT WOT, DO YOU?
(UNLESS THE USCG IS IN YOUR TAIL)

ANOTHER THING:

THE HULL ARE DESIGNED FOR CERTAIN MAX SPEED, YOU CAN PUT A TURBINE ON IT AND IT WILL STILL GO AT THAT TOP SPEED. 40MPH IS VERY FAST FOR A V-20

i wish i had a turbine...i bet i could prove you wrong.

Well, I never got out fishing the other day - was going to go today - too much rain - BUT we need it.
I did manage to raise the engine - I put it back where it was when I bought the boat - the cavitation plate is about 1/2" above the bottom of the transom. I'll let you know what that did the next time I get out.
I took off the cowl and moved the throttle all the way forward. It touched the glove box. I inspected the throttle assembly and it looked like the throttle was wide open. I determined this by looking at the shaft that the throttle plate is attached to. I tried to turn it a little, but it would not budge.
I'm getting frustrated - I love the boat - put over $4k into it (Ttop, hydraulic steering, windlass etc.).
I was looking into a Wellcraft CCF 238 - that boat would definitely take the 225 Honda.
We'll see.
Thanks for tip in using golf tees to plug holes - worked great. Had 2 screws on the console that were stripped - mixed up some hobby shop 5 minute epoxy, added some ground fiber glass - gooped up the tee and inserted them into the holes - 1/2 hour later I drilled new holes and screwed in the screws. Came out great.
