KAD 42's silicone Hoses

[Bandit]

Thanks Bandit
I don't have any problems with the cooling on my 42's. I plan to do the oil cooler, charge air cooler and the main heat exchanger at the end of 21 season. A preventive maintenance project.
This winter it's 2 new alternators 100amp (already purchased) any hoses that look like they need replacing, raw water reverse flush with Eco chemical flush. Oil change & filters, engine and also the oil in the superchargers. I have just replaced the closed loop cooling green coolant after flush out, next it's drive belts if they need it, and fuel filters and fuel water separator filter.
I would like to install isolation switches at the helm to isolate the super chargers, stopping them kicking in @1700rpm if I wish and when required. Outdrives to service and general anti fouling. I think that will keep me busy enough. I would like to get most of jobs on my list done prior to lift out. We will see how I get on. Best wishes and thanks for your advice.

The important thing is to remove the coolers. dismantle and thoroughly inspect them . The oil coolers fail where salt water cooling water seeps out and sits at the bottom of the cooler and corrodes it out there, then when corroded the reduced wall thickness of the aluminium cooler housing will fail and dump all the oil in the bilge.
