    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 .

    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...

    Stalling, sudden low idle.

    negative side of coil sends signal to tach. Some mercs will have two grey wires on negative side of coil- one for tach one for ignition module. You can take off the one going to the the tach. Others will have only one wire that splits in the harness and and goes to Ignition module and tach, in...

    Aftermarket Mercruiser parts, What are you using???

    Use the OEM quicksilver/mercruiser. The originals on my biat lasted 18 years, why screw with anything else. They will fit and last. Get a factory manual for your OD as it takes you through the job step by step

    Winterizing, use E-0 stabilized gas or install shut off valve and run carb out of fuel?

    It (carb) will dry out just sitting there. I put stabil in my tank starting Labor Day so it pulls through the system. I do this with both my boat (carb/ ethanol Free) and jetski (injected/ E10) never had an issue fuel wise with either, nor seen any chit in the fuel filters. Generally I fog but...
