    New prop recommendation

    If you want hole shot and mid range cruise I think you would like a 4 blade. That plus stern lift is why I have run them on my last two boats. WOuld need to know your WOT with the mirage but I would think the mirage would bite enough that you may not loose as many rpm with a 4 th blade as...

    Jumpy Tach

    There will be a switch /knob on the back of the tach to adjust it for 4,6,8 cylinder engines. Sometimes cycling it between the cylinders and back to 6 can help

    The leg is off

    SEI has a 3 year no fault warranty not sure if they honor it to the new boat owner, but may be the drive has warranty left ? If water got in the bellows it can cause corrosion on the drive input shaft which will ruin the seal in no time .

    The leg is off

    Yes if he had to replace the gimbal ring this would be a fix to cover the acess hole to get the steering pin on. You just want to make sure it is secure with a few screws/rivets and sealed with 5200.

    Mercarb idle speed screw and adjustment

    Maybe tje passages are a little plugged? I would go back to lean stumble spot and go out 3/4 or one complete turn, 1.25 turns at most not 3-4 turns. Let it idle 15 minutes and pull a spark plug or 2 and read them . 3-4 turns out you will eventually foul the plugs with black soot. If it idles ok...

    Missing timing tab? Merc 4.3 2005

    Yes timing light will advance the light 10 degrees so it lines up with the tdc mark. I think you have the thunderbolt V so you need it to be in base mode to set.

    Missing timing tab? Merc 4.3 2005

    Dont know why yours is different, but it you only have one mark on balancer would think it is tdc/zero Degrees. In that case either use a timing tape or advance timing light

    Mercruiser 3.0 verses mercruiser3.0/lx

    Not sure what question you are asking ? Are you asking if the 3.0 base engine will work in place of the 3.0 LX off a 1996? Or are you asking about the piece on the back ( assuming you mean outdrive where the propellor attaches) if that will swap? The 3.0 and 3.0 LX will swap bolt in if it is...

    Can't get boat even on bunked trailer.

    Yes you are being a little paranoid. Its a new boat and Im sure a big investment. but If the waves are that big you wont be going out.. I have the taller pvc covered ones they hit the rub rail vs against the gel coat, but Im sure either style will work. you may want to check how far they stick...

    Can't get boat even on bunked trailer.

    Do you have side guides for the new trailer? I would suggest getting or adjusting them and putting the trailer in deeper. Bunk trailers need to be in more water than a roller trailer. Yes the spray and the glides you mention will help it slide on if you prefer that route

    Zero fuel pressure?

    I had the same issue on my jet ski measureing fuel pressure. Maybe just put a T in and connect a rubber hose, plug it when done . At least you are making progress.

    1989 Capri Prop question

    Stainless will be a little more to fix. Would highly reccomend fixing what was on there and tyring it out before spending on new props. If you have no track record with a boat and not much experince selecting props you'll probably end up wasting money on the wrong stuff
