I am repowering my 1990 22' OR with 225 Yammie, transom mount, and would like some input about prop sizes....does anyone have the same configuration???

At WOT, the 2000 225 OX66 on my 22 Revenge is twisting 5200-5300 rpm with a 15 x 17 Saltwater Series stainless prop. I believe the WOT range for the 225 is 4500-5500 rpm. Top speed is 43 to 44 mph. The Revenge is about 300 pounds heavier than the Outrage so I would expect the same prop for the Outrage might permit the 225 to achieve the 5500 rpm max for WOT.
I'd start with the 17" and see where your WOT rpms fall. If it is more than 5600 rpm then go up to a 19" pitch.

Reel- As comment above, I'm running a 15 x 17' on an older Johnson 225, 86 OR 22'. WOT 5500-5700 rpms. It's the correct size. Sweet spot to hold plane about 3800 rpm- off 2 foot bracket (might make a little diff) with gas tank about 1/2 full. Tach maybe off by couple hundred, who knows. David

I have a 1989 22' outrage w/ 1999 Yamaha 225. I'm running a 19 pitch stainless. Pretty much perfect, maxs 5500 on a light load. I also have a 17 pitch stainless that turns over 5500, I consider it too low a pitch.
larimore posted 02-28-2002 06:10 AM ET (US)
I might add that for skiing, I'd choose the 17 pitch, otherwise I much prefer the 19.
Both saltwater series stainless.

Larimore- As per my earlier post, I'm running a 17" pitch--I pull the kids on tube, ski, or wakeboard just about everytime out. Curious about your experience with the 19" pitch. What diff in top end, hole, cruise to stay on plane (sweet spot) do you experience between the 19 and 17" props. I have 2 SS 17" props and might just repitch one. Do you ever pull kids with your boat? If so how does the 19" prop work? Finally, have you ever had a kid say to you that "I am forced to ski behind a fishing boat"? I flipppppppped. Thanks David

The 17" gives me an enormous amout of low-end pull, turns me into a jet ski, but makes cruising painfully slow because it revs so high. The 19" is a far preferable prop when cruising, and still suitable for pulling kids. I think the 19" is required if you do any significant amount of cruising to the fishing or boating grounds. The 17" is nice when your skier weights 200lbs.
I get a max of 50mph on the 19" at 5500. Though usually it is somewhat lower, maybe 47mph. I cruise easy at 30mph and 3800 or so. The 17" would wind to 5600 or 5800, I don't know the speed, but significantly slower. 3800 on the 17" would be painfully slow.
Yes, the Whaler wake is not the best for skiing or tubing. My Century ski boat was far better. I pretty much gave-up skiing when I bought the Whaler. But then any wake is better than no wake at all...

Larimore- Thanks so much for the analysis. I am going to set up the back up prop at 19". I like top end speed plus the kids are young and light, therefore, pulling them up on a wakeboard can be done just about as easily with the 19" as the 17" prop. Appreciate. David

I got the Yam 225 EFI mounted on my 1990 22' OR, transom mount. I put 3 hours on it, 73 miles, burned 24 gallons. 5000 rpm max with a 19" Yam Saltwater Series prop, 47-48 mph. Tremendous holeshot...all this with a light load, one person, half fuel, no livewell. Does anyone have any experience with the four blade props???
Peter posted 03-12-2002 06:39 PM ET (US)
In my opinion, based on your WOT RPM, the 19" prop might be just a little too steep if you are loaded up with some people and a full fuel tank. I believe that most shops like to prop the engine so its a bit on the high side of the WOT RPM range with a light load. I'm wondering why you're only getting 5000 WOT RPM when Larimore's 225 is turning a 19" to 5500. Engine mounting height could have something do with that. Through what hole is the engine mounted? The 225 on my Revenge is mounted through the second hole from top, leaving about an inch between the top of the transom and the transom bracket.

With a boat that will run close to 50, you should be running a performance series prop, whether it be by Yamaha or Mercury (which will fit). Also check with Kingfish and Louie Kokinis, since both are running 22's, quite efficiently and over 50 mph, with 225HP engines. Gear ratios in the various brands are different, so pitches will not translate between brands, however. The Yamaha gear reduction 1.81. Merc's is 1.64.
Don't know OMC's.
Either the Merc 3 blade Laser II (which I run on both of my Outrages), or the 4 blade Offshore, would be excellent Merc props for your engine. They are about $400 new, and have a Yamaha hub kit. Not familiar with Yamaha's hot props. As mentioned, your engine should be up one or two bolt holes.
reelescape1 posted 03-13-2002 07:53 AM ET (US)
The engine is as high as it will go....bottom hole. I wondered about this, and asked, the anti-cavitation plate looks like it's in the correct place...with the bottom of the boat. I'll get some more hours and play with props. Next move is a 17 SS 3 blade and then a 4 blade. Any more input would be appreciated!
Peter posted 03-13-2002 07:29 PM ET (US)
Another thought occurred to me that if this is a new motor then you're probably running a break-in mixture of fuel (fuel w/oil) plus oil from the oil tank so that might be soiling up the O2 sensor a little and perhaps the ECM is not permitting higher RPM. Just a thought. Once you run on regular non-mixed fuel, you might get a few more RPMs. These Yamaha EFI motors are very sensitive to having a clean O2 sensor. Also, make sure you run Ringfree.
lhg posted 03-13-2002 08:06 PM ET (US)
On any 22 Outrage notched transom, I would think putting the engine up on the 5th hole would be too high, since that would place the anti-cavitation plate 3" above water flow.
For running an engine that high, you may need to plug the top water intake slots to prevent sucking air and overheating. 3" up puts you in the high performance bass boat or racing category of engine mounting, and would require a Merc Trophy style 4 blade surfacing prop or equal. this would be less than ideal for an offshore Whaler. I would check on your installation.
I'm assuming you have a 25" shaft engine, and not a 30" (which you should not have without a transom jack).

reelescape1 posted 03-13-2002 09:27 PM ET (US)
Its a 25" motor. The anti cavitation plate looks to be in line with the bottom of the boat to me. It stays at the house on the trailer and I've spent every minute I can with it since!! Like a new baby!!! I'm going to get some hours on it and then experiment with props and maybe move it down a bit..we'll see. A buddy has the same motor on a heavier boat with the 4 blade and swears by it...he said I could try it out sometime. Going Friday if work doesnt screw things up...its supposed to be 77 deg. here in Chas. SC.......
lhg posted 03-18-2002 08:20 PM ET (US)
Reelscape, from your description, and with the normal 25" engine, it sounds like you meant to say the engine is mounted AS LOW AS IT WILL GO. Correct? This sounds right.
You actually might want to lift it one bolt hole.
reelescape1 posted 03-18-2002 09:33 PM ET (US)
Nope....there are 4 holes...the bolts are in the bottom holes...the engine is as high as it can be. It needs to come down some...I've got 12 hours so far. I hit some semi-rough water and it caught some air, it needs to come down. I drove my friends new 23 Triton with twin Yammie 150 HPDI's...awsome engines!! Too bad they dont make a 225 or 250!!
fireball posted 03-21-2002 11:25 PM ET (US)
A 14 x 19 will fit the bill with a 225 and a 22' Outrage. It will get on top quickly and top at 48-50. fb
