    spring vapor lock?

    Exactly as above the 1409 is a universal fit carb. The jets and metering rods tune the carb for a particular application. you will have a as good as OEM new carb then...

    Inboard 2011 4.3 Merc

    do yourself a favor and get a factory merc manual for the outdrive ( manual 14). get an oem merc bellows kit ( i think its called transom repair kit) and do all the bellows and completely reseal the transom. if you are reasonably handy the manual outlines how to replace all the seals and any...

    Inboard 2011 4.3 Merc

    is transom housing loose? When you say it leaks with drive in one position and not another that points to bellows. Where is the water coming in the engine compartment maybe get a scope camera to see exactly where on transom it is coming in.

    spring vapor lock?

    Not sure where you are getting the RPS from? On the carb I would buy a new Edlebrock 1409 take the jets and step up rods out of your old carb and put them in the new 1409 to set up it properly for a 4.3. By tune up kit what are you looking for a cap rotor and spark plugs?

    Chattering in out drive

    Did you inspect u joints and gimbal bearing? Unless you had water in gear lube or ran it low those might be more likely sources. The bearing you showed looks fine does it turn smoothly

    Is it possible to delete the power steering in a 3.0L Alpha One Gen II?

    Unless you are in salt or very corrosive environment your steering cable will probably last longer. My boat is a 2004 still steers fine. My previous boat was 25 years old and worked fine.

    did you look at the shift bellows too? My driveshaft bellows were just starting to split on edges where it rubs against the gimbal ring by swivel pins could barely see it

    Is it possible to delete the power steering in a 3.0L Alpha One Gen II?

    Take the belt off the pump and disconnect the steering cylinder from the steering arm. see how it works I have also had good luck with Lucas PS stop leak in an older vehicle. drastically cut my leaking down for a few years. Not a true fix by any stretch but helped for sure

    Propeller

    What do you get for WOT rpm now and how does that compare to the engine WOT rpm rating? As outlined above it is typical to use a power prop (aka lower pitch) for water sports but if you are already at or near WOT rpm max you may over rev. On my old boat that was under powered (3.0 merc) I used...

    Using boat with a bad trim

    I see no reason not to use it as long as it isnt leaking oil into the water. You just have to remember to keep trimming up when up are in shallow water. I ran my grandfathers boat (1966) like this for many years. It had mercs I drive (EZ tilt...) original power tilt (not trim) system with a...

    get a proper riser gasket as this is a point where if it leaks water will drain back into cylinders

    1986 Mercruiser 470 dist cap and rotor

    It was never put in a car. The 470 is a franken engine that Merc devised. used there own aluminum block with Ford 429 cylinder head... Auto parts store should be able to access the sierra marine catalog, unless they are really dumb... which is entirely possible. Places like NAPA usually can...

    Inboard 2011 4.3 Merc

    depends on how handy you are. If you are an experienced home/shade tree mechanic absolutely. if you get a factory manual for the outdrive (Manual Number 14) you can see what is involved.

    4.3l Mercruiser - failed hose test see comments

    If that is what you saw it is evidence of freeze damage from incorrect winterization. If buying it I would assume the engine is cracked and pay appropriately, like price makes sense if you have to buy a new engine. Similar thing happened to my neighbor years back got to winterizing too late had...

    95 4.3lx alpha one mercruiser cooling system question

    yes hose clamp on both sides. Only thing that uses zip ties are the gear lube line on gen 2s and folks use them on the shift bellows to shift cable connection. I think if you take your hinge pins off you should be able to pull the bellhousing back with out disconnecting the bellows. might...

    New Carb and Low RPMs

    If you have access to the factory manual for you engine or can find it online it will have jet, power valve, and venturi cluster info (part number) on it. Unfortunately we have seen many times on here where some one buys a carb either rebuilt or new aftermarket, has so many issues they end up...
