Dear all, new user, this may have been covered before, apologies if so. Mercruiser 4.3 V6. Alpha 1 Gen 2 SD. Lube level audio alarm sounding whilst on the water the other day and, whilst checking on the muffs out of the water since, it has done so occasionally at start up, but not every time. Level in the reservoir is good, lube out of the bottom screw on the drive looks clear and blue. There is however a grey sludge layer (7mm) at the bottom of the refill reservoir on the engine. I replaced the lube in the drive 6 months ago with the impeller, but not in the reservoir (Clamped this off whilst changing impeller), so this is older lube. ...is this just dirt in the reservoir and needs removing, emptying and a clean or a more worrying sign? Thankx for any help/advice GB |
