    AQ271c overheating

    292 inline 6 with prealpha drive for 19.5 cuddy

    You will also have to either have a set of studs 1/2” 20 X 7/16” X 20 to mount the flywheel and drive coupling or plan “B” drill out the flywheel and drive coupling for the 1/2” studs that the 292 uses. Be sure to replace the rear motor mount bushings in the flywheel housing.

    292 inline 6 with prealpha drive for 19.5 cuddy

    Since the 292 is taller you may have to do some cutting if the transom deck area was close to the 3.0. The pan is also deeper so you may have to do some trial fits for bilge clearance and to locate the front mount support for the alignment. The exhaust hose will have to be lengthened. The...

    Lifting the Engine Methods

    Your idea of using straps between the heads and manifolds would probably work if they are strong enough. Rig them diagonally or in 4 point arrangement and that should make it happen.

    It also appears from your #29 post that the intake manifold has an internal and external crack on the underside letting exhaust gas leak into the crankcase and into the area below the carburetor.

    OMC 400 sterndrive with 15 spline prop shaft

    I have never tried it but it is possible to mate a 800 lower to a 400 upper. How did your boat perform in relation to rpm? Does it turn up to 4000- 4400 ?

    MC-1 shift cable threading stripped

    Plan “B” If the thread repair does not work. Obtain a 1/4” NPT straight thread tap and thread from the rear through to the front of the bell housing. You could also use the tapered style pipe tap but you would may have to remove the bellhousing to do it. Sierra # 18-2248 or MCM #73723 A1. These...

    Volvo penta 3.0

    Original JB weld is good but sets hard and will not tolerate expansion. There are other sealers that come in a 2 tube injector/mixer that should hold up to expansion/contraction. JB weld may even have a product like that also. Use a heat lamp to warm the block overnight before using what ever...

    New guy - starter wire question

    Are you sure that the yellow/red on the ignition switch is not putting 12v when turned to start? As boat doc posted, the 12v has to go through the control box before energizing the boost/ slave solenoid. Check the wires under the gauge panel also.

    Mercruiser 7.4 Starter Grinding/Partial Engagement?

    To me the surface that contacts the block on the new starter appears to set the starter lower than the old one. Maybe it is an illusion but try to measure the relationship between the starter shaft and the contact pad.

    1987 5.7 omc outdrive

    Get a genuine OMC service manual. That way you will know about the special tools that are needed. Most likely you just need to wash out the upper. Since all the “V” style engines use the same lower you should be able to locate a rebuilt or used unit. Sierra Marine has the seal kit for the...

    Test stand running 70's 350 water hook up

    That will work, you may want to just watch that the water coming out the manifolds is about the same on both sides. Pinching off the discharge hose on the top of the thermostat housing will do that. Use a Chevrolet service manual or the internet that shows how to adjust the valves without...

    Seawater Pickup

    If you are going through the bottom of the boat you can also mount the through hull fitting in front of the engine. Just be sure the trailer boards will not interfere.
