    U-joint Bellows & Upper Shift Shaft Bushing

    Agreed that bushing and seal assy is pressed in the bellhousing lightly. On the bellows adhesive - only put it on the areas where the bellows and lip on transom housing fit together just a light coating on the lip around the gimbal bearing and inside of the bellows where it seals on the lip...

    I have a leak.

    Sounds doubtful at best. I would be looking that the bellows are not leaking depending on position of the drive L/R & Up/Dn , or there is another leak in the cooling system Have you looked at the driveshaft bellows closely ?

    Bellows Installation

    Yeah the newer style push on hoses are pretty cool, no clamps required . I use them a lot at work ( in larger sizes) to make air and water hoses on site with no end crimping tools.

    Mercruiser 4.3 Prop Question

    Also check the tach vs a shop tach. Would not think if you had soooo much pitch that wot was 3800 that you would have the great holeshot that you mentioned. either rpms are off or there is a tune up issue have you verified timing both intial and total? and what do the plugs look like

    Bravo 3 Refresh Questions

    Look closely at the corrosion a buddy of mine had to replace his lower housing as it cracked by bearing carrier due to corrosion. I think the later ones had two annodes on the cav plate vs the original single one. Ultimately he ended up putting a second mercathode system on it with transom...

    4.3 mercruiser vortec issue

    the push rod is moving ?? I understand the valve is closed but the pushrod should not be moving down unless the lifter is collapsed or lifter is not on the cam fully, or is the pushrod not seated against the lifter? Is this the same for all rockers? No milling the head for warpage would not...

    Outside lower unit will not go up

    Not owners manual get the mercruiser shop manuals for your engine and drive serial numbers. If you post the serial numbers people here can confirm which manuals to get. I got mine used off ebay invaluable if you plan to work on your boat

    Outside lower unit will not go up

    First pic is the trim limit switch so definitely the trailer button will only make it go up - do you have a manual with wiring diagram looks like you have some wiring stuff to work through

    5.0 oil weight and amount

    Change it annually with a good quality oil and filter and you will be ok, engine will outlive the boat. Check the oil level before use and it will outlive the boat. Winterize it properly by draining and it will outlive the boat... you get the idea... You didn't say what year the engine is im...

    Rebuild old mechanical Fuel pump or go for Electric Fuel pump

    Stick with the mechanical pump if you need to replace it. By the time you buy an electric pump, replumb it, properly wire it through an oil pressure switch /relay I can see it being a savings... unless the original pump and or kit for it is not available. Definetly do some diagnostics before...

    153 head on a 181

    5.0 oil weight and amount

    Dont over think it - no issue with quicksilver. I think the last time I looked for one the long filter was like 2x an aftermarket one. Quicksilver is the same parts as Mercury/Mercruiser, but labeled quicksilver so they can sell outside their dealer network.. so OEM quality part
