    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 Looks like the original one piece units were superseded by what you bought.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...

    Floor issue 21' boat

    If you have been there and done that before go for it. The concern of most posters here, not knowing your experience level, is that you know what this entails. Hopefully it is not too bad. Will be interested to see how much rot is there

    Solas stainless 4 blades all the same?

    So by lowest level you mean tabs are down more to push bow down? The engine rpm will bounce like that on the limiter as it drops spark to cylinders until rpms come down. If engine temp climbs at that rpm you need to look at the cooling system, if impeller has not been replaced I would do so...

    Floor issue 21' boat

    Given the obvious rot would want the guy to drill into stringers and transom. The water that rotted the floor had to go down somewhere... Like rust on an old car what you see is likely the tip of the iceberg.

    Tb IV intermittent spark ?$#???

    If it is a good ground then that means the sensor is bad. Not surprising since it went scuba diving ... Would recommend getting an OEM sensor vs the aftermarkets ones. this is an OEM quicksilver from the quicksilver store on Amazon...

    Tb IV intermittent spark ?$#???

    Follow the service bulletin he posted I circled where you are at in it - by striking the white and green lead to ground you are simulating what the sensor in the distributor does to get the coil to fire. If it does fire at coil the sensor is bad if it does not fire follow to testing for bad...
