Avon SR4 with 25 HP - Would it work

I am currently thinking about buying an SR 4M, but i only have a 25 hp outboard left over from my old boat.
Would it work, or do i have to get a new outboard?

If it would work, what speeds would be possible?

Yes it will work - best with a 2 stroke and leaning forward to plane - we run that setup for decades in our local yacht club - 25 knots

It's a 25 HP Mercury 2-Stroke weighting 52 kilos. I don't really care how fast it will plane because i'm not going to race it.

I'm usually helping out at alot of Rowing/Sailing Clubs and now my old boat is gone i'm gonna fulfil myself the long-nurtured wish of getting an AVON

By that token, a 6hp would also 'work', tootling along at 6knts. :-)

I used to do that on my 4.10 Wiking SIB but with a 2 hp
It works but as soon as you get passed by a bigger ship it stops working due to the wake

What about a 40hp on 4.7? Underpowered by a lot or just a little?

That will work well and will be well balanced
