    Ford 302 issues

    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

    The main thing you have to know is what is the maximum rpm, then you will know which propeller you need.

    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.

    1988 GM 5.7 stalling when slowing down

    Did you purchase the Sierra# 18-5514 kit? It came with the correct coil. The ohm readings are on the internet.

    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...

    Get a volt meter and connect it to the + side of the coil and perform the same test.

    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.

    Seawater Pickup

    1” NPT pipe is plenty enough water supply. 1/14” I.D. hose will fit over it. Consider that in the drive there is a much smaller pipe which will deliver enough water for a sea water cooled 5.7 But as we know will not cool a fresh water cooled V style engine.

    Seawater Pickup

    I would only use the scoop style, it has a grill that will keep out debris.

    Seawater Pickup

    It does not matter If you do not mind the extra “Rooster Comb”. They are all suitable for the job. They can also be mounted through and on the underside of the trim plane. I had a 24’ Campbell once that was set up that way.

    Remove quadrant gear and Stern leg is stuck in down position

    When the drive is down does the steering go in both directions without a bind? Pump some grease into those fittings while the bolts are loose. I cannot imagine what would keep the drive from not being able to lift by hand with the quadrant gear removed.

    Seawater Pickup

    Do not be afraid to go through the bottom with a valve. The one advantage is one less “rooster comb” behind the hull. The “Y” connection is a definite good move to keep the drive cool and also works with a flush out . Greco # TH 1000 Through hull 1” NPT pick up Groco # IBV 1000 valve The rest...

    Remove quadrant gear and Stern leg is stuck in down position

    Remove the rubber bumpers and just loosen each of the mounting bolts 1 turn. There is no way the ball gears can restrict the drive from coming off. With the bolts loose you should be able to shake the drive enough to remove the quadrant gear.
