    Smartcraft gauge questions

    I am looking to install a smartcraft gauge for my 2019 merc 150 4-stroke (serial # 2B602057) so that I can have access to all the cool information it provides on my motors functioning... I am thinking just the smartcraft RPM gauge...but I cannot seem to figure out what harness I will need to...

    What Happened here??

    4.3 OMC Cobra drive My buddy brought his boat by after it stopped working for him. Looking it over I found this! Gear lube is coming out of it. Unfortunately, he keeps boat in the water and didn't realize anything was going on until it was too late and boat stopped moving while in gear...

    Upgrading from a 2-stroke to 4-stroke

    I am planning to bite the bullet and upgrade our 2001 Merc 200hp 2-stroke to a newer 2018 Merc 150 4-stroke. I am wondering if my controls and wiring harness from current set up will work with the newer motor, or will this upgrade involve switching those over as well? Thanks!

    2001 Merc 60HP 4-stroke carb question

    Alright folks, I am struggling here and feel like I must be missing something. I am working on getting a 2001 Merc 60hp bigfoot running again. After seeing the condition of the fuel lines and primer bulb, I am certain a carb cleaning is needed. Here is my question...how do I get the 4 carbs...

    Different gear ratios on lower unit?

    Hey all. A buddy of mine wore out the upper gears in his 4.3 Cobra lower unit. We are weighing the option of swapping out the gears versus replacing the upper half of lower with a used unit. Since we do not have a machine press, switching gears is near impossible. My question is this: I...

    Winterize a 1993 7.4 Bravo Gen V

    Hey all. I've winterized numerous other Mercruisers, mostly smaller 3.0 engines. With the 7.4 is there anything additional I should do to ensure all the water is out? No issues with changing gear lube, oil and fuel filters, oil, and winterizing the inside water system. My question is focused...

    2001 Merc 200hp acceleration issues

    Hey all. I have my 2001 Merc 200hp outboard (2 stroke). It has recently started having a hard time accelerating slowly. If i punch the gas, it takes off like a bat outta heck, but when I try and slowly accelerate the throttle it will bog and stall out. I'm thinking it needs a carb cleaning...

    Lowrance GPS issues??

    I recently bought a Lowrance Elite ti fish finder. I have it all hooked up, but the internal GPS is not working! If I go into data sources, it shows GPS, then the next tab shows "Auto (invalid)????" what does that mean? I've tried everything and it will not lock onto any satellites. Just...

    Breaking in a rebuilt engine

    Hey all. This past winter I had to have some serious work done to my 2001 Mercury 200hp. It needed to have a piston sleeve bored out, new piston, block honed, new head gaskets, and new rings installed on all other pistons. My question is what exactly should I do for breaking in the new piston...

    What happened to my lower unit??

    So I winterized my 2000 Merc 200hp outboard for the cold northern NY winter. I changed the gear lube to ensure there was no water in there to freeze. Well...I went out today and there is blue (what I am assuming is gear lube) all over the snow around my outboard. We have had a few spells of...

    Why can't I set my timing?

    Hey guys. I am completely stumped here. I have been working on my 2000 Mercury 200hp outboard, carbed model. I replaced the trigger, and now I cannot get the timing set! I am trying to set it to the cranking specs, but It will only go from 0 to maybe 10 BTDC and no further. What in the heck...

    What am I missing here?

    Hey everyone. I am going a bit nuts here trying to figure out why I can't get my timing set. I have a 2000 Mercury 200hp (carb) outboard. I replaced the trigger assembly because the wires were rotted out. It started up and idles fine, but wouldn't really take the throttle and would not go...

    2000 Mercury 200hp (carb) timing specs

    Hey everyone. I am just wondering if anyone knows the correct max timing specs for a 2000 Mercury 200hp carb outboard. In the manual I was looking at it states that the max timing is set at 24 BTDC on one page, but then also states 20 BTDC on a different page. Should it be 24 or 20 BTDC...

    2000 Mercury 200hp (carb) timing questions

    Hey everyone. I just replaced the trigger assembly on my merc 200hp motor, and want to check the timing before I take it out. I have a few questions. Looking at the numbers in the manual for my 2000 merc 200 (carb), I see that it states that idle speed/pickup timing is 0-9 ATDC, the cranking...

    Trigger assembly and flywheel removal question (2000 Mercury 200hp)

    Hello again everyone. I am almost done re-rigging my boat with the new-to-me 2000 Merc 200hp motor I purchased. The last thing (I hope) holding me back is the trigger assembly. The wires for the plug end of the assembly are shot, so I'll need to pull the flywheel and replace the trigger...

    2000 Merc 200hp trim not working.

    Hey guys. I am still in the process of rigging up a "new to me" Merc 200hp to my tri-toon. My newest problem is with the trim system. When I press the trim up and down buttons on the actual motor, the relays just click, but the trim motor doesn't move at all. When I press the up, one relay...

    Pontoon motor height question

    I know this question has been asked a bunch, but I keep reading different answers, so I figured I put it out here and see what the consensus is. I have a 2001 25 foot Crest tri-toon. It had been running on a 1989 black max 200hp merc. I am finally swapping that motor out for a 2001 Merc 200hp...

    Help determining if I have a seized motor or lower unit issue

    I have a 1987 Black Max 200hp. I thought I had a starter issue, but upon further investigation found out that the flywheel won't spin freely. It will spin about 7/8 of a rotation in either direction, but then stops. My question is this: do I have a seized motor (thrown rod of piston issues) or...
