    Stupid question…

    Not off of what is shown. In video linked you see water coming out the idle relief ports on gimbal housing. In your video there is none coming out there. This tells you that no water is coming up to the thermostat housing. Even when the thermostat is closed it should be sending water into...

    Stupid question…

    No water is coming out the idle relief ports on bottom sides of gimbal housing so you are not getting water up to engine. with a 140 thermostat should run 150-160 max. did you check if the impeller is spinning on the metal center in it. to back flush remove drive , remove hose at thermostat...

    Whats the deal with "High Milage" conventional and synthetic motor oils???/

    typically additives that will condition seals that may be getting dry and brittle, some components to fight sludge build up. I have used them in my engines but hard to say if it does any better than the non high mileage version. Biggest thing is just change the oil...

    Shift control replacement

    Do yourself a favor and get the correct controller. To do number 2 you would need to be able to read the wiring diagram and make the appropriate splice connections. As mentioned the trailer button is only needed to keep you from over trimming at speed. Can be an issue with U joints if you all...

    Pressure test Alpha 1 Gen 2 - do I need to block something

    As stated about the only time you need to plug anything is if you split it and are testing the halves separately. Follow the air leak to see where it is coming from. It is possible the oil valve in the upper that is supposed to close when drive is removed is holding pressure. Also you dont...

    Aplha 1, 3.0 - Exhaust & Manifold Help Please

    In higher temperatures and salinity levels of the ocean the corrosion will be increased. 3 years does seem very quick as most folks are thinking 5-7 years. As Scott says post some pictures of the manifold to elbow cooling water passages. It is possible that your mechanic is recommending out of...

    Prop seals Bravo 3

    Use heat on the bearing carrier retainer and to pull the bearing carrier out. On my alpha I ended up getting a 3/4 drive breaker bar to get the retainer loose, bust my 1/2" one on first try.

    Plastic where zinc goes.

    Depends on a couple things - I got 3-6 years out of my gen one impellers. This is freshwater northern lake so 30-40 hrs annually. I found the OEM merc ones lasted 2x the sierra ones. Had the boat (1991) for 20 years and did 3 or 4 changes at most. Best bet is to go a season or two and open it...

    Best Battery for MerCruiser 888 (1976 Ford 302)

    Yes most folks are converting to PMGR for weight savings and easier install. Only issue I have heard is sometimes the PMGR is slightly shorter than the original and you need to get new bolts, which is not a bad idea anyways

    Plastic where zinc goes.

    Make sure you get the correct annodes (zincs) for the water you are in. Magnesium for fresh water Aluminum salt, brackish or fresh - I think what merc uses as OEM Zinc for salt only Personally I found less corrosion using OEM Merc Magnesium in fresh water vs aftermarket magnesium ones

    Solas Amita vs OEM (Yamaha)?

    I don't think merc has nearly the amount of selection for the B3 props he mentions, and I think the thread was about AL props so apples and oranges. Certainly Enertia, revolution 4 etc are tough to beat on single prop set ups. My good friend has 24 ft Crownline Deck boat 350 Mag/B3 with the...

    Best Battery for MerCruiser 888 (1976 Ford 302)

    Maybe an acceptable substitute. May just be luck but the batteries have gotten at NAPA seem to hold up well n terms of longevity. The cheaper ones have bought at Walmart or other cheaper auto parts stores, not so much. While a few bucks more might be a better investment

    Bought a Used Boat, but what is it?

    I didn't even consider the OB side as except for small tinnys over the years never owned one. Only asked because my alpha gen one and gen two powered boats have been great for me. Had to read it twice as I didn't know they offered a blender....I get it on the dog clutch, I grew up with them so...

    this is the day I sold that boat in 2016 (25 yrs old not a lick of rust on the pulleys ... easier in freshwater.

    Bought a Used Boat, but what is it?

    I think you are right, probably more boat builders have gone out of business than are still in business... Its hard enough getting any useful info from the boat builders still in business. Honestly asking - what is the hatred of Merc based on - did you have a bad experience on a past boat?
