    4.3 crankshaft/housing oil leak - next steps?

    the plastic doesnt bother me that much as most of the time I have had zero issues. On my dailies which are toyotas zero issue with plastic covers, wifes mini cooper the valve cover is chit and the engine temp they run at is a dumb idea. Mini also uses a tone of plastic in the cooling system. All...

    4.3 crankshaft/housing oil leak - next steps?

    there may be a different issue didnt Chris (former mod here) have a years long thread on a front cover oil leak? I think he traced it back to casting defect on the pan that was cracking the cover. Had to get an updated GM pan etc , but took him 3-4 engine pulls to work through it...

    Looking for alignment tools

    The guys have you straight with tools needed. Only other thing I would recommend is to check your transom and stringers for rot when you get the old engine out. Give the age of the boat its highly likely you may find some

    4.3 crankshaft/housing oil leak - next steps?

    I would think your 4.3 pan given the engine vintage is likely the ribbed cast aluminum one. While it could corrode, less likely than painted steel ones. If it is painted steel easy to refinish while its out and you can coat it with bed liner for long lasting finish.

    4.3 crankshaft/housing oil leak - next steps?

    the two biggest differences are electrical and fuel components, the rest is basically the same stuff GM uses in truck engines. before Merc started making their own 4.5 and 6.2 engines they were buying base engines from GM. THis is an example of what a base engine is and contains-...

    Frozen engine manifold cracks and likelihood of block survival

    Entirely possible they didn’t drain the manifolds would pressure test the block to find out. as others have said a bunch of issues. Anyone can make a mistake but if the dealer winterized it this isn’t a good first look... have a friend who is in WI and his marine mechanic had his boat down as a...

    4.3 crankshaft/housing oil leak - next steps?

    The timing cover and seal are just stock GM parts so there is no marine seal. Would think you can match it up off of year via rock auto or napa or the Chevy dealer do you own research but I would imagine a 2003 4.3 would be the same as you 04 engine… rock auto lists a front crank seal as in...

    Resealing Alpha Upper

    that should be plenty wide just has to cover where the seal rides. How much is the sleeve vs a new yoke? If you dont have it get a factory manual for your drive has step by step how to do all repairs and any special tools needed. Usually can find the tools used on ebay for half price.

    Maybe my turn for new boat time

    that is the sensible thing to do. a few years back toyota was doing 3% or so for certified used. Basically used it as a cash flow spreader 1-2 years. in northern climates no sense making payments on something you can only use 3-4 months a year.

    Maybe my turn for new boat time

    yeah it seems like prices on boats are down across new and used. Good time to buy if you have the cash

    The ignition module on a EST is in the distributor. Est is often used for points replacement or to replace NLA merc thunderbolt systems when the module dies.

    I/O (Sterndrive) Conversion to Outboards

    Volvo Penta engine coupler runout … aka wobble

    I would just replace the coupler based off that history, unless its supper easy to jank the engine. Some boats are more work than others.
