Would A Single 130 Work?

I currently have twin 1991 Yamaha 130's with the Whaler drive. They are both 25" shaft lengths & I have the WD that can use a single engine. If 1 engine gets past it's useful life, what do you think performance would be like with a single 130? Of course, I would move it to the center & change the prop. The dry hull weight is 2500 according to the spec sheets. One of my engines is starting to show it's age & the other seems to be in better condition. With the twin engines, top speed is about 55mph at 5600 rpm & it doesn't matter if I have 1 or 5 people on board, so I think it could go even faster with a more aggressive prop. The current props are 19x? stainless & they are flat on one side. Sorry to not have all the info on the current props. I currently get 1.9mpg at 32mph at 4100rpm. With gas getting so expensive, it would also be nice to get better mpg even if the boat goes slower. I would be happy with a top speed of 30mph & cruise at 20mph. Does this sound realistic? I am not able to afford a 4 stroke at this time, but I think I will make it through this season with the twin motors. Thanks for any opinions.

Did you determine your speed with a GPS? The reason I ask is that I'm only getting about 45mph on my 1988 22 Outrage WD with twin 1988 150 Johnsons. I'm running 15x17 OMC SST stainless props. I know that my motors have somewhat low compression.

No way an Outrage Cuddy WD will go 55 mph with twin 130s (or even twin 150s for that matter).
I suspect a single 130 would not be very satisfactory on that boat but if you were committed to repowering with a single motor in the future, the new bolt holes would do no harm and you could always try it.
Barry, I think your speed is just about right.

I have checked with the gps that the boat goes over 50mph. I think the gps is accurate because it is a handheld & is is the same as the speedometer in my truck on the freeway. The boat chine walks at full throttle & I don't hold it there very long. I admit to rounding the speed number to 55, but over 50 is definite. When I bought the boat the previous owner said it goes over 50. I told him that if it does, I will buy it. He floored it from a dead stop & the boat went ballistic out of the hole & I had my handheld gps with me. I am not making this up. There are some pictures of my boat on sharkfishing.us Select shark boats, go to page 2 and scroll down. There is a really cool video taken from my boat of a huge mako shark jumping. Go to videos, select jumping mako. Thanks again for the responses. Keep them coming.

A single 130 on a 22' Outrage with W/D would not be a very enjoyable package. The engine would be at WOT just to keep the boat moving at a satisfactory speed. It could probably get up on plane, but other than that, it would be a dog.
FWIW, my single 250hp on 22' Whaler w/W/D gives WOT of 46mph, but I have a sizeable Tee Top with full front and side curtains for wind protection. Those rob alot of speed.
One day I'll try and see how fast she would go w/o the curtains, but I bet it steals couple of knots.

BTW, that Dry weight for 22' with W/D and Cuddy has got to be more than 2500lbs.

First of all, your props are not 19 x >>>>> theres no such thing as a 19 diameter for an outboard.
The number 19 is your pitch.
It would take a 21 pitch prop to get 55 mph @ 5600 rpms.
Remember this, a gps measures your speed over the bottom, not over the top of the water, so if your going with a 5 mph current, your gps will read 5 mph to fast for speed over water.
The exact opposite is true when going against a 5 mph current, your gps will read 5 mph slow.
If I'm not mistaken, you should be running 20" shafts instead of 25".
As far as running that boat on 1 single 130 hp, you will hate everything about the boat & engine.

John, according to the catalogs, the dry weight for the 22' Outrage Cuddy WD is 2,500.
