    Trim sender vs stick

    you can splice it or try and re-solder it. Yes a full repair has the wires going through the transom which is best done when the bellows are being done and everything is completely apart. If you are old enough to remember boats before trim gauges you can also leave it alone ....

    Tachometer bouncing

    Bad coil?

    You need so e way to test for spark when it stops running. Would check the following when it starts acting up. 12 v on positive side of coil. soark off coil to distributor and from dist to plugs since you say its rich check for fuel dripping down boosters into carb throat, if so measure fuel...

    What 6 cylinder Mercury is this?

    Engine is very mechanically reliable if reasonably taken car off. The mc1 outdrive is also good. The issue may face due to age is some parts being no longer available as both the engine and outdrive have been out of production for like 40 years…. You can bolt on a new R/MR/Alpha one gen one...

    what do you see wrong with this picture?

    Don’t know never had one. Would assume they would drain out like max when changing. There must be some way to not make a complete mess

    Water on top of Intake Manifold

    check the oil for water if you think the intake gaskets are leaking. Possible it came down from the hatch cover depending on design .

    what do you see wrong with this picture?

    That is a remote oil filter pretty common on mercs. The fuel/water separator is usually down on lower left front of engine the oil in the bilge may not be a big deal could come from corroded timing cover or from drive seal leaking into bellows and into the boat. What would worry me is the...

    Alpha One Gen 2 prop shaft seal replacement

    I was going to make or modify jaws on one of the pullers we have at work. Not sure if I can make my own tool to remove the nut that holds the bearing carrier in or buy one (dont think they were too much$$). Luckily I have access to the shop at work ...

    2016 Mercruiser 4.3 TKS (Carb) Winterization Procedure

    No I have the five point drain, just no need to put the plugs back in the manifolds unless you fill the block up and it starts filling the manifolds when thermo housing overflows. Yes you can leave the AF in for corrosion protection. A lot of saltwater folks do this, but if you boat in fresh...

    2016 Mercruiser 4.3 TKS (Carb) Winterization Procedure

    No need to use so much AF unless you get the good stuff which is PG based with corrosion inhibitors. I drain mine probe the holes, take the hose off thermostat housing coming from the drive pour about a half gallon that will back flush out the drive. Put the two block plugs and the J hose plug...

    Alpha One Gen 2 prop shaft seal replacement

    Went to take the boat out to winterize it yesterday (had not used it in 3 weeks) and noticed a oil sheen from the outdrive when I put it in the water... also noticed the lube bottle was down by about half, which I have never seen before. Take the prop of and predictably find a bunch of fishing...

    Alpha 1 Gen 2 Y-Pipe Flapper

    I think im getting the same thing. Looks like the original one piece units were superseded by what you bought. I came up with the part numbers below but i suspect it is what you have.

    89 Horizon 180 with stock 4.3 upgrade questions

    This is good advice. no sense going through it unless you upgrade significantly. You may be money ahead getting a vortec 4.3 from a wrecking yard and going that route. A good running engine 4 bbl intake and carb and you would be at 225 hp . I would keep the alpha one gen one drive vs going...

    2003 Mercruiser 4.3 TB-V No Spark

    SO with new sensor installed you strike green/white wire from module to ground and you get a spark off the coil? Or you only tried this with the ruler? if yes to striking the wire with new module I would agree that yes the new oem sensor is bad and try the next new one and see. Either way I...
