    Knocking sound - what is it? [video]

    I wouldn’t install that gasket with those ports. Would think someone swapped the head or manifold. Maybe merc tech support can offer a solution or just order the earlier style gasket and see how it matches up I believe the Barr kit is you can mix and match earlier and later manifolds and heads

    5.7 EFI stalls when warm and shifting into gear

    I think what he was getting at - If it maxed out at 4400 rpm just means that this set up was over propped a little and would have been at some points lugging the engine which can lead to detonation and higher exhaust gas temps being under max load a lot due to over pitch. Would suggest going...

    Did I over prop?

    You have it backwards increasing pitch reduces rpm at wot. I would expect 800 rpm less with this. You either have an incorrect drive ratio or engine that needs maintenance attention , or both. You need to go down in pitch not up by 165 stringer you mean engine or drive. If he used a drive...

    Sound deadening

    They had me use PL polyurethane construction adhesive- again were particular about right materials for the application. I think I went with the cheaper end of what they offer (eggcrate foam which was what was in there from factory) probably spent $125-200 and it made a noticeable difference...

    Help with engine timing

    There should be a mark or several marks on the balancer as shown in the photos. If you only have a TDC mark you can use an advance timing light which will offset or advance the light so that you can use TDC and set it for 8 or 10 deg advanced so light will be timed for tdc mark

    Water in reservoir

    As others have mentioned you have a seal issue on your outdrive, maybe several seals are bad. In the stickys there is a protocol for pressure testing the drive to identify which seals are leaking.
