Adjustment of the ratio between prop pitch and throttle setting...?

[John Denney]

Hi all, well she is now launched and sat quite happily in the local canal! It all went well and no leaks which is a blessing! Just a question about the throttle.....
I had to motor 50 yards up the canal and discovered that I seem to need a lot of throttle to get the boat to move forward.... it may be me, as I have nothing to compare it with, but I was wondering if this is normal?
The prop does not go to "fully coarse" until the throttle is pretty much wide open.... is there a special way to set up the relationship between pitch and throttle setting? I do remember being very careful about putting it all back together and followed the instructions very carefully.... so I am sure it is right as far as the reassembly is concerned but I am unsure if I should be able to do some "fine tuning".

Just off to sort out all the bits of string and connect the electrical things from the mast now - luckily it is only a 15 min drive away!

I have just been back to the boat to have another fiddle with the engine. I think I just need reassurance that mine is set up properly....
This is what happens... (boat is tied up!)
When I push the throttle forward the engine revs increase but there is only a "modest" amount of thrust. As I increase the throttle setting to about 75% the engine actually revs about the same (maybe a bit more) - and it feels as if it is working hard and then it is apparent that the boat is straining at the leash and trying to move forward - loads of water being pushed rearwards. If I go to full throttle the engine starts to "labour" and the revs actually drop a little - as if it is stalling - is this normal?

Reverse is the same but I seem to get more reverse thrust with a smaller movement of the throttle lever... I think I should have made a small video.. not sure my description makes sense!
Anyway, thanks in advance for any thoughts.
