Which 30hp for hi performance? yamaha ??

[Jason123]

Im looking for a 30hp engine and top end performance is the main requirement. I foolishly sold my 25hp suzuki and replace it with a 4ohp 2cyl tohatsu. The suzuki was just as quick. They don't make these 2 stroke suzuki engines anymore. Any ideas for a hi performance 30hp? im leaning towards a Yamaha. Any idea which would be the better out of the 2 or 3 cyl model? How about johnson or evenrude?

Not enough info, Jason.<br /><br />What boat is it on? What prop are you using? What actual speeds are you getting?<br /><br />There is no reason that the Tohatsu shouldn't be faster and quicker than the Suzi.<br /><br />Hp is HP.<br /><br />Let us know.

New Mercury 30 Hp 2 cylinder/2cycle is the same engine as 40 Hp 2 cylinder/2cycle. Since its derated, it should have unreal low end torq..or go for the forty which is same size and weight and fly!!!!!!!!!!!!

Its on an 11 ft aluminium sea-al super skua. Tohatsu had std prop but suzuki had stainless prop. Not sure of size. I sold suz to my friend with the same boat and we raced. I forgott to mention that he was carring a passenger and more weight and there was still nothing in it. Looking at specs suz 499cc and tohatsu only 493.<br />I need a short shaft for this boat. Merc don't sell 30hp (merc not tohatsu) in aust in short shaft. Only 40 hp available in short is tohatsu or johnson/evenrude which would possibly be a bit heavy. Thinking of 3 cyl yam 30hp or even 3cyl 40 hp tohatsu. much larger engine than 2 cyl tohatsu.

Jason,<br /><br />No matter what you buy, the HP is going to be pretty close to stated rating.<br /><br />However, three cylinders will be smoother and may be of larger displacement, thus greater lower end torque.<br /><br />If it's true top speed performance you want. Look at max. rpm ratings and prop according to that max. rpm. <br /><br />Prop selection and availibility should play into your choice. In that instance, I would think that Evin/Johnson and Merc. products would have greater selections. Mercury has a great prop. subsidiary.

What ever made you decide to replace the suzuki with a tohatsu, that is just wrong ... but glad you came to your senses and want correct this with a yamaha .... if performance is what you are looking for, you can never go wrong with a yummie .....
