    Wrong timing set up

    you wont be able to turn it by hand unless the plugs are out, then it shoudl turn fairly easily. did you correct the firing order and timing and did it run ok afterwards

    Alpha lower unit crack in strange place?

    You can clean it out, send it down and jb weld it . Same thing happened to my grandfathers boat occasionally had to re expoxy it but ran that way for years no issue

    1990 5.7. 260 Overcooling at idle.

    I think You should be running the non restricted gaskets with your style thermostat housing ( cold manifolds). As AD said that isnt the issue thermostat should hold back water enough to keep it at temp. i would guess you have a mismatch between the thermostat, manifold crossover, thermostats...

    Confused with 5.7L Timing Cover Replacement

    You have a 96 and up vortec block, which is actually better… you can see 8 vertical intake bolts and the plastic cover plus electric fuel pump… just order parts for 96 and up the plastic cover is technically not reusable …

    1993 larson 4.3 coil

    The coil wire is probably the issue.… ill let chris answer but i think the .6-.8 ohm is beyond the accuracy of the typical low buck multi meter.

    1993 larson 4.3 coil

    Lots of things it could be. He can ohm out the coil vs specs chris gives. If its bad replace it. would start with checking contents if fuel filter for anything but fresh clean gas. verify the condition of ignition components prob needs a carb rebuild

    Impeller puller screw

    I think you will find the VP hold up fairly well. Most of my neighbors with VPs are getting over 6 years on them in typical lake boat use.

    Mercruiser 3.0 tks noise at idle or no wake speed

    yep as stated the driveshaft, gimbal bearing, drive input shaft and vertical driveshaft are turning all the time the engine is running. On an alpha onky the propshaft doesn’t turn when in neutral

    Mercruiser 3.0 tks noise at idle or no wake speed

    I would check the accessories by disconnecting the belts as well. Might be a gimbal bearing, does changing the drive or steering angle make any difference? Its typical to find black wires with ring terminals in the engine harness that are unused. Mine had one as well. Seems like they may prep...

    Trim not going up with switch on shifter

    This means the trim limit switch (round puck on port side of gimbal ring) is bad. It limits how far up you can trim before needing to use the trailer button. You can jumper the switch out in the engine compartment easily, as the switch is a pain to change and best done when doing bellows etc.

    Pasty oil coming out the valve covers

    Draining is the best way -If they were clear of debris then that should drain it completely. Possible it is only the water crossover in the intake. I can't recall if there is a plug on the water cross over of vortec 4.3s that needs to get pulled as well? You could pull the thermostat out and...

    Tahoe 2150 CC Height on Trailer

    It would only be accurate height if someone else had the same trailer as you. Different trailers would give you different heights

    Would look at fuel filter empty and look at contents ignition system what is condition of cap rotor plug wires and plugs. Assume you have a thunderbolt ignition . May want to look at sensor in distributor especially if it has the exposed terminals which is the older design. try opening gas cap...

    Pasty oil coming out the valve covers

    Would bet the block is cracked under the heads in the lifter valley looks like it wasn’t properly winterized. Are the outside of the exhaust manifolds cracked as well?

    Alpha one gen one outdrive 1.98 ratio. A earlier R or MR drive will also bolt up as they are essentially interchangeable with the alpha gen one.
