    Mercruiser 3.0 Fuel Issues

    Its really three separate tune up functions get factory manual set choke per factory manual make sure choke doesn’t hang up and fully opens may be too closed and making it too rich thus black smoke soot on transom. set idle mix screw, idle speed screw, timing per factory manual. If idle mix...

    Compression ratio 5.7l

    If its in a 1996 boat it is possible it is a 95 engine. My 91 sea ray had a 1990 vintage engine and by serial number one of the last alfa gen ones built , 91 was transition year to gen 2. Really depends on boat builders inventory of engines. my 2004 boat had an original engine showing a june...

    DP 1.95 SM outdrive hosed

    Your best bet here is to talk to your insurance company. Good friend of ours- same thing happened last year shortly after spring splash. Mechanic found fishing line damaged seal insurance paid for new or reman of drive. Entirely possible prop shaft(s) bent, two sets of seals and shaft down...

    Gelcoat cracks around mercruiser transom plate opinions and repair questions.

    Might be why the sealant was put there to keep it from shipping more. As long as transom is truly solid you 'll be ok. Looks like in this photo there are two layers of yellow? either re gelcoated or painted?

    More testing on Sharrow prop...

    I'm not missing anything...don't be condescending. Yes it doesn't pay off in most situations (if you go way offshore a burn several hundred gallons a weekend it may pay off), completely agree. Would love to see real use feedback from someone vs article written in a mag supported by a company...

    More testing on Sharrow prop...

    Im also a big fan of aluminum for buy in price and understand why u may use it, but Dont compare Al to stainless let alone higher end stainless, not an accurate comparison. agreed the buy in is 2 x lab finished props would like to see a real world test aka no advertising dollars at stake …

    Old ford 302 no spark

    Listing says the advance comes in earlier which is prob ok. I would worry about total advance dont think you want more than 30 total to keep detonation at bay

    Anyone use a 2017 kia Sorrento AWD/4wd high output engine?

    Exactly- I found when buying my Highlander the XLE model (5500# rated) vs LE model (1500# rated) has same drive train and brakes only differences are engine oil and trans coolers

    Compression ratio 5.7l

    If you get 9.5 and run 91 with factory ignition advance you will be fine from a detonation standpoint. I would think the flat top is better than the factory dished piston for detonation potential .

    Merc 470 no crank

    yeah these guys are probably too young to know how a points system bypasses the resistor during cranking

    Compression ratio 5.7l

    Depends on gas you want to use , octane Piston profile may play a role if you have a quench build. But generally 9.5 or so if you want to use pump gas. A touch higher if you have quench pistons.

    Gelcoat cracks around mercruiser transom plate opinions and repair questions.

    Ive never had to deal with transom rot but general consensus is you can only really tell by drilling , if wood shavings come out dry just seal with 5200. transom hardware being tight is a good sign.

    Merc. 5.7 Repower wiring

    No difference on choke coil between a 2 or 4 bbl carb. I put a edelbrock 1409 on my previously 2 bbl carbed 5.0 merc, used the factory purple wire it works fine

    Merc. 5.7 Repower wiring

    My merc takes the purple to the choke, but In the drawing you posted the purple yellow is fed via the oil pressure switch as well As getting power off starter when cranking

    Overheat on 5.0 with SX outdrive

    As lou said water doesn’t compress so when you get water in a cylinder vs air and fuel, when the piston comes up on compression stroke there may not be enough room in the combustion chamber to accommodate The water volume. The compression ratio of 9 or so to one if you have a cylinder half full...

    Merc. 5.7 Repower wiring

    Mercruiser runs the electric choke off the purple wire going to ignition on. they say to do this so as not to lower voltage off the ignition circuit. On my old GTO i ran the electric choke off the wiper circuit upstream of the wiper switch. Easier in a car where the fuse box is. 4 ft from the...

    Gelcoat cracks around mercruiser transom plate opinions and repair questions.

    normally when somebody runs a bead of sealant around the transom housing it is leaking either from a drive impact or rotten transom. Did you drill into the wood of the transom to verify they are sound? Are u sure that is gel coat and not a repaint of the boat? If the transom is indeed sound...

    Mercruiser 3.0 Overheat stop working

    Start with a compression test. how long was it hot and how hot did it get. May have smoked something electrical. If you need to check for bent pushrods just remove the valve cover, but if it got hot a vlave is probably hung up and why the pushrod is bent. the DDIS all dogde speak of is obvious...

    Leak at shift lever alpha 1 gen 1

    Not air but you will get water in the gear lube turning it milky and potentially ruining bearings and gears. What did you lube look like when you drained it ? Assuming you likely just winterized? If water gets left in ther and freezes can crack the housing
