    Alpha one gen one installing lower out drive

    I built a carriage to reduce weight on me as I moved OD spline into housing/coupler. I used 8"X 8" x2' wood. Old Railroad ties will work well to build up where you rest OD. You may have to shim for a better parallel fit. Then you slide od (not lift.) into housing. Obviously, you should remove...

    HELP! Outdrive stuck.

    U may have to wiggle OD spline into coupler, if it is not shifter keyway issue. However, if you changed gimbal bearing, insert alignment tool and keep forcing it into couple while beating tool side to side to center bearing inside housing.

    Getting hot at WOT.

    Bravo-itus????? Salt used??? Check it out! Did this happen before on the older motor? Temp guns are not perfect. I've owner 2. 1 differed from the other one by 10 degrees. Have you checked its accuracy? Have you replaced temp sensor on motor? If so, did you use a lot of Teflon tape or some other...

    MerCruiser 5.0 (Carb Engine) will not turn, what is this part?

    Before proceeding, what caused the fire? Usually, it is battery or fuel related. Check battery charge and cables going to starter. Of OK, manually jump starter using screwdriver or something else to cross contacts at starter. If motor spins, look for any burnt electrical wires related to motor...

    88' Mercruiser 165 harmonic sound

    Here is an old trick to determine if you have a bad plug. Get you some rubber gloves and pull each distributor plug wire at distributor while examining tack. You sure timing is correct? It may be advanced too much and causing pinging. Just an idea...

    Engine will spin up in RPMs boat hardly moves

    You may have to take prop to a good shop and pray it is defective. If not, lock motor from spinning, best way. Remove prop and replace lock nut with a couple of jam nuts. Using a breaker bar and proper socket, try turning prop shaft. Good luck.

    Which coil to use?

    We are. We cannot get fire out of main coil wire with helm switch on. 12 volts is coming to + side of coil. Main lead should arc between spark plug contacts but no arc. We will rotate with our stb motor's working coil to further rule out coil. Motor has set for 4 years due to my health issues...

    Which coil to use?

    My coil may have gone BAD. It says "Mercruiser" on the coil's body, but faintly. No other writing is available. It is installed on a an older 350/stroker carbureted motor using a MC TB5 ignition system. I believe a Chevy automotive internal resistor coil could work on the TB 5 but I am not 100%...

    Living in NW Florida and having a boat for 65 years, I learned to never keep an I/O stored wet in salt water. An inboard is a different story.

    saltwater 5.0 weak points

    That old of a boat and used in salt water, for peace of mind, I'd rebuild a 350 from a junk yard to a 6.2 and add close cooling (antifreeze). Pitch old salt water exposed iron.

    What reason causes the water leaking into gimbal bearing house?

    Some gimbal houses do not have grease valleys (travel) and grease fittings. These bearings are sealed. At least my Bravos didn't have the grease fittings.
