stupid question!

what is the theory behind off setting your outboard?
is it as i understand to counter act the prop wanting to turn the boat to the right? if so how does it work??

its to couteract prop torque, normally applies to high hp small boat scenarios.

if you mounted a high hp motor on a smallish boat in the centre, then the prop spinning clockwise would have the opposite effect on the boat, the boat will want to turn anti clockwise, hence moving the outboard over to the stbd side counteracts this.

Exactly - I have seen several boats with the outboard offset to one side. Some argue that you can counteract just as well setting the toque tab, but to my knowledge this will give the boat a tendency to lean over to one side at high speed...
On my Fletcher 199 the engine was offset about 3 -4 cm, and it
remained level at maximum speed ( after driving throug a bit of chinewalking )..

Opinions on this subject are like arseholes - everyone's got one.

IMVHO there is no hard and fast answer - offset is just one part of the boat setup, and therefore can't be considered on it's own. Every other bit of how you set the boat, and how you intend to use the boat, will also have an impact.

If it were me, I'd put the motor on where the previous engine was, save myself the hassle of filling holes in, and not worry about.

If it was me I'd phone Terry or Colin, or ask little Pete on here.
For whats it's worth I'm an offset person.


Edit: I could have phrased that last bit better !!!!!

you will get better drive with the engine mounted in the centre which probably means a better top speed. As i said you can achieve the same as offsetting by mounting all the heavey stuff on the stbd side.

It's about usable speed. The P21 that I raced with Howard could have been set up to go quicker but we took the usable route. We werent the quickest on a calm day but average to rough was where the advartage lay, could keep the power on when others were lifting off. That set up worked very well. There is no hard fast rule it's suited to the driving style/preference of the individual
