I have a 24' outrage with twin merc salt water opti 150s. After 10 years in salt water, it is time to repower.
My mechanic is recomending twin 4 stroke yamahas - 150 hp each.
I would be very interested to hear your views on what to repower with and any good or bad experiences.
thanks in advance

I have always been very impressed with Yamaha. You might want to consider a single 4.2L F300 (weight is 560lbs or so). Lighter than your twins and will probably have same peformance or better. A set of twin F150s will weigh in at 1,000 lbs. Not sure what your stern weight limitation is for your year outrage.
I just repowered a 22' Guardian that previously had twin yamaha F150s on it with a single F225 and am very pleased with performance.
Rule of thumb is that twins loose 30% of efficiency over a single motor setup. Of course redundency may outweigh this factor for those heading offshore great distances.

You can compare the weights of the different 115 thru 150 hp motors here in our Current Engine Choices and Weight article:

I have a friend with a 24' Outrage that he repowered with a single Yamaha 250 OX66. That is a perfect combination. The boat is good for 47 MPH and can (and does) haul a LOT of weight.
If I were you I'd consider the venerable Yamaha F250 or the new 4.2 liter 250 Offshore.

I agree with Shad - if you don't need twins, the Yamaha F300 Offshore would be a great choice. You'll save a LOT of weight, your mileage and maintenance costs will improve and it likely will end up being cheaper than F150s.

Some 8 years later and the Yamaha 300 is still going strong
Tops out at 36 knots so lost 2 knots top end but saved a load on fuel
Boat definitely handled better with twins

Thanks for the update. I also have 24' Outrage (1995) with a Yamaha HPDI 250. Will be repowering in the future. My brother bought a new Yamaha 250 and put it on his non Whaler 22' center console. It is a beast for sure. Same block as your 300. i am torn between the Yamaha 300 and the Suzuki for my re-power.
Can you tell a positive difference with the weight on the back being lighter, Did the twins just track better?

I am surprised that a single lower unit and same hp would be slower. Have you tried messing with height adjustment as 4 strokes tend to like higher mounting for best performance.
24 Whalers so far.... |

The 300hp is lighter than the twin 150hp mercs The water line had to be redone as it was some 4 inches Higher in the water at the stern I am very happy with 300 and would not go any less. The Yamaha 300hp is a great engine. I have just over 500 hours on her and she is a beast
I repowered my 19 guardian a few months back with a150 hp Yamaha and it was a close contest with the Suzuki 140 hp At the end went with Yamaha as it was a better price and longer warranty
There are lots of opinions on Suzuki vs Yamaha and it may just come down to price/warranty/and local service
Twins definitely tracked better especially at low speed

Thanks for this. I had not tried adjusting the height. It’s worth a try

That is the first time I have ever heard a yamaha was cheaper than a Suzuki and had a longer warranty as Suzuki in the states is 6yrs.
