    Alpha 1 drive quick question

    is that why the ladies call you 50 cent? Yeah I don't know either. Was assuming they dont just fall out? or did yours corrode?

    Alpha 1 drive quick question

    My concern would be if it froze and pushed out the Welch plug I assume you didn’t water test the boat ?

    cold weather break in

    When I bought my new GM long block from Michigan motorz a few years back they insisted on rotella T4 conventional 15W40 for break in. Also wanted conventional oil for first 100 hrs before switching to synthetic Your lower temps may play into it but I’d think you’d be fine using it. Long block...

    Shift shaft seal / carrier seal / oil o-ring?

    do you mean you have lube leaking down the shift shaft in the bellhousing onto the lower ? This may be from the poppet valve in the gear lube line. If you dont pop the drive on quickly any residual lube in the line will leak out when the drive is an inch or so off the bellhousing.

    Shift shaft seal / carrier seal / oil o-ring?

    no good deed goes unpunished... On my entire drive the only seal that was somewhat compromised by wear/age was the shift shaft seal. All other seals were in nice shape, except for the prop shaft seal with fishing line... So you had no leaks - just replaced the seals while you were in there?

    Shift shaft seal / carrier seal / oil o-ring?

    I tried just replacing the seal on the shift shaft not the whole plastic housing it is in, could never get the seal to to stop leaking , ended up buying the bushing with the seal in it. Sierra is better than most aftermarket parts, but the OEM is best in my experience. My boat is a 2004. two...

    Thermostat GLM13230 OEM # 87290A4

    verify the thermostat is opening, would not be the first time a new one didn't work. Put it in a pot of water see what temp it opens at and if it opens fully.

    Shift shaft seal / carrier seal / oil o-ring?

    most likely the carrier seal below the water pump. relatively easy to split the drive remove the water pump and pressure test the lower by plugging the hole where the quad ring goes. Usually can clamp a flat piece of metal on it. Get 12-15 psi of air pressure in there and put soapy water on...

    Out drive water flow incorrect?

    where it connects to the lower is not what I was talking about. There is a clip farther up the tube that holds it to the bellhousing casting. The clip goes into a 1/4“ hole in the bellhousing , i suspect this where the water is coming out. you will have to look farther up in there than where...

    Out drive water flow incorrect?

    its normal. If you look in where the water is coming out behind shift lever, there is a 1/4” hole. There should be a clip that holds the speedo tube in it. With drive up this is open to exhaust cavity which is where the wate4 is coming from

    How much water pressure is too much, for running on the hose?

    you must be close to the water tower. Do you get water hammer when the washing machine valve closes? Newer construction will have a reducing station in the house, but what you mention is pretty typical for public water. the 3 homes we have owned on city water have all had 75-90 psi .

    How much water pressure is too much, for running on the hose?

    I wouldn’t worry about it any excess will blow out the muffs

    Alpha 1 Gen 2 - leak & transom service questions

    if the Y pipe was leaking and you stick a hose in bellhousing the water should go through the engine and leak out the Y pipe, engine running or not. I think the places above the Y pipe that could leak are driveshaft bellows, water in pipe fitting, steering shaft seal. Not sure if shift bellows...

    No Spark – 1998 MerCruiser 5.7L Thunderbolt V Ignition

    A lot of folks will use a Delco EST to replace the complete TB system when the module dies due to TB module cost/ lack of availability. The Delco is an OEM quality system and modules when they die are cheaper, although we have seen folks on here getting bad EST modules or having trouble putting...

    No Spark – 1998 MerCruiser 5.7L Thunderbolt V Ignition

    in addition to testing above. A bravo module is not made to work with a shift interrupt, so i dont think it will go out of gear. I test ran my engine when I repowered with a bravo module (alpha set up as well. If I recall it worked with the bravo module with the shift interrupt wires from the...

    Should I use a kicker when trolling in a 4.3L Mercruiser?

    you are already on the lower side of pitch with a 17". the only thing you may want to keep an eye on is wear on the coupler, you can actually get more wear on the splines trolling as the solines load and unload due to wave action. Not saying this is a deal breaker just something to keep an eye...

    The easiest and most precise way to install a gimbal bearing

    if they are beating on it the bearing is most likely cocked in the transom housing. Going in or out it shouldn't take that much force. The tolerance ring on the outside crushes a bit to hold it but shouldn't need anything than a good sized hammer to drive it in. Use the OEM bellows for...
