if you have it the motor - try and see - not everybody is speed freaks!

SR4 are found in many sailing club as rescue boats operating 2 up - the amount if camping gear you at will determine the speed.

unless you can get good money for your 25 , and sure you an buy a reliable replacement !

of course i will try with the 25 first... the boat im heading towards might need some restoration first though..

my motor is relatively new(2001) and i got it quite cheap.

we will see.

I went to Fair Isle yesterday on my 4.6m rib with a 20 honda on the back. 87 nautical miles. Not fast 18knots max on journey but went ok.
So yes, I'd say 25 hp on a smaller boat would be fine. But I will be getting a bigger engine at the end of the season!
Cheers

You'll be fine with 25hp.

Mine has a 30hp Yam and flies.

Keep the boat light (no unnecessary batteries / a frames / electronics / big anchors / 100 litre fuel tanks) and the hull clean and it will be great.

Ours goes well in all sea states 2 up and have got it planing with 3 adults and 4 (small) children on flat river water.

Your 25hp will need to be a long shaft btw.

Go for it and if/when you want more speed trade your engine for something bigger :-)

The difference between a 2-cyl 25hp Merc and a 3-cyl 30hp Yam is more than the numbers on their lids.

Why not just put the correct bloody hp on it?

Buried in the many replies was a nugget of information - the SR4 needs a long shaft engine. OP - is your 25hp short or long shaft?
