Hi,

I have a Supra Launch SSV from 2002, with the Indmar Assault TBI engine.

I have recently installed Perfect pass to the boat, but it is not working very well (the unit is hunting severely and cannot keep speed).
After following some trouble shooting tips I found that my Throttle return spring is very weak and that should at least be part of my problem.

Now, I cannot really locate which spring I should get.
I found one thread here, but for a different engine, that suggested Indmar part S631206-1.
However I can only find that online from Australia.

I live in Sweden and there are no Indmar dealers close by, so ideally I would want a part no that I can order online. And even better if there is a cross reference to Volvo Penta or Mercruiser because that way I could get it locally (instead of paying 20-30 USD shipping + waiting 2 weeks).

Thanks!
Mike
