Thanks - interesting to read your comment about noise - I had previously thought / had heard that 4 strokes made less noise than 2 stroke motors?

For info....in my search for an outboard, I was actually told by a Suzuki dealer that the throttle linkage is the only difference between a 4 and a 6hp!
Cant remember exactly, but he mentioned something about
fitting the linkage in the alternative position, but to do this means cutting the existing end off the cable and fitting a replacement end (available from bicycle shop!!! He reconned this woud be about a 20 minute job.
This may make more sense to those who own the motors?

I think most tests have shown that the 4stroke is quieter.

On ours I dont think you would need to alter the cable.The throttle arm on the carb is restricted in its movement by the stop.The shorter stop on the 6 would allow more movement.
if I get over to the boat tommorow i will attempt to photograph it and post it on here.
re the noise factor.Our Suzuki 4 stroke is considerably quieter than our old 2 stroke 5 hp Yamaha .My kids found the yamaha noise unbearable with their more sensitive hearing.

I'd agree about the noise, I bought a Suzuki DF4 last year and I reckon it's quieter than the Honda BF2 I had before. Nice little motor and they were doing a spring fitting-out deal at the time for £500 at participating dealers.
When I bought the Suzuki the dealer popped the top off and showed me the throttle-limiter screw you can remove (or adjust?) to increase it to 6HP once it's fully run-in. I haven't tried yet as I haven't used it much but will give it a go this spring.

The L shaped metal plate my able assistant is pointing to in the pic is the throttle stop on our DF4( 2003 model)
I have been told that swopping the plate for a replacement part for the DF 6 allows the throttle arm to move further increasing it to 6 hp.
If that is the only mod needed you could uprate a 4 to a 6 for about £15 and 2 minutes work. Saving nearly £300.
This would probably invalidate the warranty but you could allways swap them back again. /forums/images/graemlins/wink.gif

That's amazing! Good photograph - thanks. The wee L-shaped throttle stop even looks like it's got "4" written on it, to make the engine a 4hp... Damned clever!
