    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...

    Can I upgrade my 2010 karavan trailer with kodiak discs?

    So I just did an oil change for the first time on my new boat. The motor is a 2010 Mercruiser 4.3L After putting in new oil and running the motor for about 30 seconds, I check the dipstick and the oil is still black! I don't ever remember this happening to me on my old boat. What gives? To...

    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?

    Dealer told me Bayliner is not making the discovery 192 anymore. True?

    Dealer told me Bayliner is not making the discovery 192 anymore. Is there any truth to that? The dealer may have even said they didn't make any 2013s either but I can't really remember for sure if he said that. He said they probably aren't making any more 192s for a couple of years. Something...

    Trim questions for an alpha one leg

    Ive been using my boat for 6 years now and when trimming down all the way I alway go by hearing the trim motor change in pitch signaling the leg is completely down. Now I am wondering if the trim stop puck is supposed to detect that or is it just for up? I know that when I trim up all the way it...

    Fuel economy - 3.0 vs 4.3 on a 19' boat

    Im looking for a 2008 or newer Bayliner 192 discovery and I can't decide on the motor. I'm thinking the 3.0 will be ok for my needs since I don't do any skiing. I'm also not planning on buying a Kicker so I think the 3.0 would be better for that. Does the 4.3L burn that much more gas than the...

    3.0 mercruiser puked water/oil out the valve cover yesterday

    Let me start by saying I did something really stupid when I had my old riser off. I sprayed water down the exhaust manifold probably flooding the cylinders. I thought it was a water way because there was rust in there. Yes very stupid. So I pumped out the water with my oil change pump and then...
