    The paint chipped off easier than I thought. I did use a bit of paint thinner to loosen it up.

    New Exhaust Manifold surface prep? 4.3 Mercruiser

    I just purchased new exhaust manifolds and risers for my 2010 Bayliner 192 with a 4.3L Mercruiser. The manifolds are painted where the exhaust gasket goes and some of the paint has chipped off. Do I need to chip off the rest of the paint?

    Acting like a spun prop hub but it's not. What do I try next?

    I have a 2010 Bayliner 192 with a 4.3L Mercruiser and a Alpha 1 gen 2 leg. The other day when I was on the water, I couldn't get up on plane. The fastest I could go was 16mph revving at 2800 rpm. When I push the throttle down, the engine revs to 5000 rpm but the boat doesn't go any faster. So I...

    Can only suck out 3 liters of oil from 4.3tks

    Hi, I have a 2010 4.3l tks mercruiser engine and I’ve never been able to suck much oil out and was wondering if this was normal. I’ve have a tube attached to the oil pan that I can pull out through the transom drain. I attach a pump to it to extract the oil. I’ve also tried extracting the oil...

    possible overheating issue

    I have a 4.3 mercruiser TKS. I just put in a new thermostat because the old one was sticking a bit. The temperature is about 175-180(just a little past 175) when warmed up and cruising. When I go from cruising to idle I notice that the temperature rises a little bit and I get a few beeps from...

    Why did my plastic drain plug break off?

    I have a 2010 bayliner with a 4.3l mercruiser. A couple weeks ago while I cruising along at about 3400 rpm, my boat overheated. It turns out the engine block has a blue plastic wing nut drain plug and the top broke off draining my engine block. I fixed it and fast forward to yesterday it...

    Help: adding a fwc to 4.3 merc with dry joint

    I'm in the process of adding a San Juan fwc kit to my 2010 4.3 merc. Kit is mc-340. The instructions say to remove the hoses that are attached to the bottom of the risers which I did. Now I stuck my finger in the hole expecting my finger to go down into the top of the manifold. To my surprise...

    Can TKS(turn key start) be retrofitted onto an older 3.0L?

    Hi, I have a 2002 Bayliner 1952 Capri with a 3.0L Mercruiser WITHOUT TKS. I find that it can be a pain to start sometimes. Does anyone have experience with a 3.0L with TKS? Is it much better than not having it? Can it be retrofitted onto my 3.0L?
