Outboard for Avon R280?

Hi all,

Been searching the internet for an outboard for my Avon R2.80 Rover Rib. Have seen mentioned people putting 40hp on these!? when its only rated for a 8hp (I was looking for a 10hp)

Question is... what kind of engine can be put on one of these!?

Cheers!

RIBase
If it's rated for 8hp - then stick to that. If you go against the manufacturer recommended HP you'll invalidate your insurance, or worse endanger yourself and anyone onboard.

You may have a choice of single or twin cylinders at 6hp. Get the twin - it will be a better engineered and smoother engine with more torque. Much quieter too. Only downside is slight increase in weight and separate fuel tank.

I had an 310 with 8hp on it a few year back - flew with just me & one other. Suffered with 4 up , but then thats only 2HP each + the boat ( mine was not light with the double floor, sperate tank etc ! 310 was rated up to 10 , but I decided that for an extra 400 on a new engine I could manage without the extra 2hp ! Stick with themax ( or just under) recommended & you cant go far wrong IMO

Ooops, I came across a 9.9hp last night and bought it...

Will this reduce performance at all?
