Hi
Been looking on and off over the last couple years at upgrading to a Serie(s) 9 Antares (size up from my 760). The older 2000-2006 inboard blue ones (with the protective skeg under the prop) are what I'm looking at like the pic (not the later 9 or outboard ones).
They are quite similar to mine but a couple I looked at recently had issues that don't occur on 760s (and could be expensive to repair).

I wondered if anyone had any advice on the following:
1 - KAMD43P engine - one boat had the belts removed from the supercharger. Aside from taking longer to get on the plane could that have damaged the engine (running rich)? I was wondering if it really matters if 90% of the boat's usage is outside the SC band of operation (i.e. on the plane over 3000rpm or under 5knts in the harbour/pottering about).
2 - Side windows crazing - anyone ever replaced them?
3 - One boat's flybridge roof overhang above the cockpit was split open all along the rear edge - I think those roofs are balsa cored - is that repairable if water has got into the core? Or is the roof now knackered?

Any advice welcome.
The one below is just for illustration, not one I looked at.

Do you mean KAMD42?

Personally I would reinstate the SC. Can't see any reason to disconnect unless you want to run long periods in the SC rpm band, which isn't usually ideal in terms of fuel efficiency anyway.

The other reason it may haven been left disconnected is that is has failed. For the sake of a belt, I would want it reconnected and tested working on a sea trial before committing to any purchase, even if planning to leave it disconnected afterwards.

Sorry, no help on points 2 and 3.

Ah, yes, sorry typo - it was a KAMD43P to be exact.
Yes, that's a good point about reconnecting to test the SC hasn't failed entirely. Agreed.
Thanks

It might not be efficient but a lot of people like to fish at the speeds that a supercharger would normally engage.

Yes I've read about that, trolling in warmer waters (or US).
Appears some people install a SC on/off switch at the helm (for the pre-EDC motors) which would be handy.

If I'm fishing the engine is off or briefly on tickover.
