I bought my 1988 V20 fisherman center console about 8 months ago. It came with a 2004 Honda 225hp motor. The prop is a SS FOUR blade 14 1/4" by 17. Wide open it goes 44mph (GPS) and is turning at 5500 rpm. Seems to me that it should do better than that. Get about 3 mpg.
Any comments or tips would be appreciated.
thanks
 
there are a couple of members that have 200's on their boats and get close to 50mph, I've got a 150 and can get near 40 out of it w/ a stock 3 blade aluminium 15x17, you SHOULD be doing better than 44 w/ a 225. There are a couple of good links about props in the link section...or you can ask for some input from our resident propmaster REELAPEELIN....he seems to be pretty much in the know about propellers, and he's got a Honda too. Good luck
 
Silly question, but are you sure your GPS is set for MPH and not KTS??? 44 kts is a hair over 50mph. I top out at 49mph with 200 Merc with a t-top.
 
Thanks, Phester...but I'm not really a prop expert...I just read V-20.com ;)...

Jackman, 44 does sound low, but the 5500 is more of an indicator to me that it's prop'd wrong...my 150 tops out at 42 mph at 6000 rpms...

what's the Honda's max rpm rating on the 225?...to ''get it all'', that's what to shoot for and your top speed will result...

Try these guys;

They make props FOR Honda and they'll evaluate your set-up and tell ya what ya need ;) ...
 
MOst 150's will twist a 17p prop to about 5500 rpm's on a v-20. That Honda should be rated to turn about 5000-6000 and you want to shoot for the top of that range.. Something seems askew because w/ a 225 you should be turning that 17p prop closer to 6400 I'd guess. A 225 should spin a 21p on a v-20.

Right off the bat, aren't those 4 blade props slower on top end to begin with? I think they are made for holeshot.

I wonder what a 3 blade with a larger diameter, say 15 x 17 would do? :-/ ??? I think the pitch of 17 is fine.
 
ok looked it up and it says that 4 blade props are as follows
for Super Holeshots & Handling Props (Reduce Pitch 1-2") - 4 Blade

Supercupped For Extreme Motor Elevation (Reduce Pitch 3-4") - 4 Blade

I'd say you needed the same prop in a 15 pitch or just get what BR said get a 15 x 17 prop stainless
 
I called the guys at http://www.ptprop.com/.
Talked to a Bill L.
He took all my info and said something about a 8% slip, and said that's not bad. He recommended I keep the prop I have.

The 44 mph reading from my GPS is in MPH not knots - thanks for bringing that point up though - I have been known to to do silly things like that.
 
jackman, that's surprising...that's a LOT more HP for only 2 more mph than my Honda 150...did PT ask or talk about max rpms from Honda?...
 
reelapeelin,
At first he said I had the wrong prop.
He said the big Hondas like big diameter props, and that I should probably go to a 15 or 15 1/4 " prop. Then he said the pitch would have to be reduced to 15 degrees - he said I probably wouldn't like it because the top speed would go down to about 40mph. Then he did some calculations and said I was getting only 8 % slip, and that I would be ok with the prop I have. He did say that prop was great in rough seas. I was out 2 weeks ago at Key Largo and was trolling in 5' seas - the boat and motor were great.
 
I'm sorry, but you should be running much better than 44 mph. I have a 150 Merc and I turn a 14 1/2 x 17" pitch and I run 42 mph. I run a four blade prop and I may lose 1-2 mph but I come out of the hole faster than a three blade prop.
 
I agree with you 100%. I took the motor in for 2 recalls. The mech said he noticed something (in the engine) that was keeping the engine from going to full throttle. I will have to talk to him and find out exactly what that was all about. Now that I think of it, when I have the level at full throttle, it's very close to the glove box - maybe that is keeping the engine from going to full throttle. I will check into both things.
Thank y'all for your help!
