I don't know where Nicho got his info from, but I've had confirmation from Volvo that they have over 500 ECU's in stock..
KAD32 speed relays are currently unavailable, stock due September.
I believe it varies depending on the exact engine model (i.e. KADP44-A, B, C or KAD300). I have KAD and it's possible to pootle along at 8kts or so with the supercharger disengaged. And also at cruising speed you can reduce throttle at certain engine speeds and get the supercharger to disengage...
Thanks.
Mine is pretty bad (boat is in Spain so it only gets cleaned every few weeks). Covers are only a couple of years old so I'd like to get them looking new again.
Easiest solution is an independent ICC assessment. No pre-requisites, can be done on own boat in a day and providing you know roughly what you're dping most assessor will be keen to pass you.
