I recently purchased a 1994 Outrage 24. My plan is to purchase a single new outboard in the 250 hp range. I am interested in what opinions people have regarding 250 Yamaha HDPI, 250 Merc Optimax or 250 Merc EFI.

I just repowered my 1993 Outrage 21 w/ a 2003 Yamaha 225 4 stroke. So far we are very happy with it - quiet, will push the boat at 46 mph w/ a 17" prop (Y-saltwater series), is quick out of the hole, and very economical. New motor was $20K in the box + $1,500 to rig it.

Funny i see this post because yesterday i did a sea trial in a '97 21' outrage that was pushed by a 1996 EFI 250 hp Merc. Supposeddly the motor would push the hull 48 - 52 mph, quick hole shot, etc...

But we had problems, the engine missed,timing was off wouldn't get up, sounding like electrical.... changed plugs and fuel filter to no avail.....

the man who owned the boat was disgusted and embarrassed that this happened. He had all the service records, but this was just bad luck.

Glad it was on his ticket, versus mine. Anyway it'll be in the shop next week and we'll do it all over again when she gets out.

My Uncle had a 1994 24 Outrage with a 250 Yamaha Saltwater Series (He sold it 3 years ago). I fished with him several times out of Miami. The boat performed well, but I do not have any specific numbers. If you want I can give him a call and answer any specific questions you may have.

He purchased the boat new in 1994 and had it until 2000. It had 230 gallon fuel capacity, t-top and a 25 hp kicker. He longest trip he took on the boat was from Miami to Long Island, Bahamas and back (400 miles one way).

Thanks,
Carl

Conrad,

My plan is to install and FEI 250 Yamaha like your uncles. I would be interested to know what his top speed was at medium load, 1/2 tank 2-3 people etc... and Miles per gallon. I suspect top speed in the low 40's and 2.5 mpg based on past experience. What prop was he useing, a 15-1/2" x 17" ? Also, what did he like about the ride of the boat and what did he think could have been better?

Any info greatly appreciated,

John

One month ago, I purchased a 1994 Outrage 24. It came w/ twin CR Yamaha 2 Stroke 150's. I just repowered and put on twin CR Yamaha 4 Stroke 150's. My fuel tank is 195 gal, and because I'm planning on doing some running from Miami to the Bahama's, I kept the option of the second engine.

The previous (original) owner told me he once lost power to an engine, while on his way to the Bahamas. He just raised up the "dead" engine, finished his trip, and returned w/o every a worry.

I don't know what the weather is like up there in WA, but in S. Florida the weather can get a bit hairy in a very short period of time. I woldn't want to get stuck in the middle of the Gulf Stream and bad weather, w/ no power.

With twin 150's, and the fuel effeciancy of 4 strokes, I expect to get nearly 580 mile range @ 30mph x 10 gph. I based this on the my performance experience with my BW 1980 v20 Outrage that I repowered w/ a single 150 HP Yamaha 4s.

Why are you sticking with just the one engine? Why not twins?

How about a 250-HP Mercury Verado? They may be constrained by supply, but that sounds like it would be a good match for your application.
