    Mercruiser 3.0 TKS - Hard to start when semi-cold

    Yea, so the engine starts fine hot and cold (say the first start of the day). BUT the second start (like after you start it again after engine been off for 2-3 hours) is much harder. My starting procedure is always Neutral position, cold semi-hot or hot. Your comment makes sense from my...

    Filling coolant reservoir 3.0 TKS?

    Tested the boat for a long journey this weekend and think temprature were just fine (see pictures). But a bit worried about the coolant recovery tank condition. As you can see - coolat is right on bottom (cold engine). 1. I checked your steps but I heard it good be a problem to refill if I...

    Worth flame arrestor upgrade for Mercruiser engines?

    I wanted to clean my flame arrestor today but think I accidently broke it. I think it will still work with some gluing and also because of the screw holding it togheter but looking for upgrade but maybe with some better quality. Are flame arrestors the same for all carburetor engines? However...

    Mercruiser 3.0 TKI engine crank half time - never starts

    I used these: https://www.boltsnmore.com/product/stainless-steel-lock-washers-304/ Don't know how they could damage ends, they will keep tight between threaded studs. Will not touch anything but top connectors. Should be good and will keep connection tight.

    Mercruiser 3.0 TKI engine crank half time - never starts

    I see now your point. Jesus when engine is running at low rpm there are really crazy vibrations down there.
