    Transom plate / Gamble housing through bolts (Alpha1 Gen1)

    Me too, 4200 around the head of the bolt when I installed the transom.

    4.3 engine mounted raw water pump inquiry

    A pump in the outdrive is submerged and less likely to get freeze damage than an engine driven pump on cold days. Like you, I live where I often go boating during cold times. I'm pretty good at draining everything when I pull a boat.

    Alpha One Gen Two outdrive vibration

    Failing u-joints can present as fine when testing by hand manipulation. Unfortunately the only way to really know is to pull them apart and inspect the bearing surfaces, and if you do that it is easier to just replace them.

    Alpha One shifting problems

    First thing is always try adjusting to strict specification. Also check cable routing. Chris's video is a great tool to adjustment process.

    Alpha1 350 raw cooled boils and ticks rapidly after short time on muffs

    The reason for lower temperature thermostats on open cooling the lack of pressure. With closed cooling and 14 pound cap the water won't create vapor bubbles until after 220ƒ. With open cooled motors the low pressure allows vapor bubbles to form at 170-175ƒ or even lower when at altitude. Bubbles...

    U-joint bellows ring

    I found when I did them that it went really easy after I got the rubber ridge and groove perfectly lined up and seated down into the bellhousing groove.

    Nice teardown! You can see the corrosion from here. Little bit goes a long ways.

    Frozen Prop on SX-M Duoprop, Seeking Advice

    The divot in the center of the shaft is for the live center when the shaft was finished up on a lathe. Measuring the diameter of that shaft would make it super easy to get a piece of pipe to fit over it. There are so many sizes it boggles the imagination. You will have a local steel supply...

    Frozen Prop on SX-M Duoprop, Seeking Advice

    Also, you may be able to drill or cut holes in the round body of the prop to get puller hooks in solid. You will have to be very specific on what you push against though, hence my request for a little better picture of the hub. I have never worked on a DuoProp VP - I am no help on where to push.

    Frozen Prop on SX-M Duoprop, Seeking Advice

    IMHO the prop is less spendy than the lower gears, bearings and case. I would be hard pressed to hammer much on anything. Problem is especially bad in bearings and gears and it only needs a tiny surface distortion to wreck one of them. Can you give a better picture of the hub area on that propeller?

    Frozen Prop on SX-M Duoprop, Seeking Advice

    I think you can get some heat on the prop hub. Wrap the seal area with an aluminum heat shield made from a soft 16 gauge or thinner piece of aluminum. Then use a small oxy acetylene welding type tip to heat just the hub. The expansion will go a long ways towards loosening that press fit you...

    Alpha1 350 raw cooled boils and ticks rapidly after short time on muffs

    Sounds to me as there is no exit for the water going to the manifolds now that the gaskets are closed off...

    Merc. 5.7 Repower wiring

    I did not put a fuse on the interrupter circuit. 10 amp circuit breaker plenty for the pump. I stuck a relay to power the pump. I just connected the wires together coming from oil pressure switch and starter wire (purp/yellow) to switch the relay. Then I put a 10 amp circuit breaker on the...

    what manual to buy.

    Mercruiser OEM service manual. Nothing else comes close.

    Mercruiser 3.0 Overheat stop working

    Exactly. Don't guess that valves aren't opening - pull the valve cover and look at them while cranking.

    That one looks like a chip off a gear tooth. Need to do some investigating, sorry to say.

    Milky oil Mercruier 3.0 / how to pressure test engine ?

    You will need to pressure test block. And to test manifold you either remove it and do acetone test or leave it on, block off the exit and pressure test it with the block.
