I'm think of doing the swap if everything fits well.
I have the larger carbs already on it.
Thanks

You would have 18 on the cowling if it were the 25/18 jet.
In your model year the 35hp (outboard)was a 3-cylinder.
Yours is the32 cu. in. 2-cylinder cross-flow.
For your engine you already had the correct 30hp cylinder and crankcase and the large intake manifold. Same as the 30hp.

I plan on having someone do the work for me, porting, carb reeds......if I could get 10 mph more I would be happy. Let us know how it works out for you.

not sure what hp's were available in 2000 but the 20,25,30 and 35hp motors all have the same powerhead and the different carbs and or manifold intakes dictate how much HP the powerhead produces for those modelsrktman said:Has anyone replaced their 25 hp powerhead with a 35 hp unit on a 2000 Johnson motor (jet).
