Hi Paul and :welcome to the forum. A 9.9 motor will get it moving but a 450HD would be a very heavy boat and personally I'd be looking at 15 horses minimum :thumbsup :drive

:welcome Paul. If it's rated to 30hp, a 9.9 ain't gonna cut the mustard, It will have to work very hard. Of course it all depends on your budget. You can always slow down a big un, but you can't speed up a tiddler. :waterski

I have a 9.9 on my 3.8m Honwave and it isn’t really enough. It pushes me around ok, but the engine struggles to get to full revs as it doesn’t really have enough power.

Go as large as your budget and strength will allow. You may also find that you get better fuel economy from a large engine running comfortably rather than a small one working hard.

Of course, if you already have an old 9hp 2 stroke then use that to start with. The outboard that owes you nothing is always the best - the price of a new outboard will pay for a lot of fuel! :rofl

If you are not reaching maximum revs then you are over propped. It will perform a lot better with a smaller pitch prop.

It's not, it's bang on the lower end of the recommend rev range.
