    1969 Merc 7.5 hp Lower Unit Dis-assembly ???

    It's alive . . . :) The old Merc 7.5 hp lives again. :thumb: . I found that the engine would stay running at higher throttle settings . . . So, I started it in reverse and ran 3/4 of a gallon of a cocktail of new 2/3 2-cycle mix (50:1) and 1/3 seafoam. It took a couple of hours to run through...

    1969 Merc 7.5 hp Lower Unit Dis-assembly ???

    I figured something out . . . I had the idea of fighting torque with torque, so rather than clamping the LU the way I had it, I put it in the workmate so that it had more torque to resist the torque of the wrench. . . I was able to put enough torque with the breaker bar to get the ring nut to...

    Trim works going down but just clicks when trying to raise up

    Why do 'we' always have to do the research :D I believe this is the trim pump you have . . . The same solenoid is also for the starter . . . I usually keep a couple on the boat in the spare parts drawer :)

    1969 Merc 7.5 hp Lower Unit Dis-assembly ???

    Hi Gang, I decided to start working on my old-ish 1969 Mercury 7.5 hp . . . It needs a whole new water pump along with a prop shaft bearing and new seals. Right now I am 'trying' to get the retaining 'ring' nut off and am wondering it there are any tips/tricks to getting the 'nut' to break...

    Question about Swapping out Shift/throttle controls . . .

    I'm no expert when it comes to throttle/shifter controls for boats . . . sort of a phobia of mine :rolleyes: My boat currently has these 'standard' Quicksilver controls (which are 24 years old) . . . (twin engine, single lever each) . They are nothing short of horrible compared to what I was...

    Covid-19 Heat Resistance

    Things have been improving in MA . . . but I'm not so sure after this weekend. Seas were calm and we went to a place which is known as Black Beach/Great Sippewissett Mash . . . I had never seen so many boats there, and for many - social distancing was out the window . . . :eek: Lots of boats...

    Bravo 3 Shift Adjustment . . .

    Hello Everyone, The starboard engine started acting up today on the way back to my home port after a day-long outing. It would not go into gear once in the harbor and at no-wake speeds. (Bravo 3 outdrive) We had to stop a few times for traffic in the channel, so I was in and out of gear a few...

    Keeping an I/O in a salt water slip

    Lucky you !!! I would apply a barrier coat (or 2) (Interlux Interprotect E2000) first, then the anti-fouling paint. Your first application of AF will need about 3 coats, then probably a single coat on a seasonal basis. I use ePaint EP2000 anti-fouling paint. There are all kinds/brands of...

    Brake Leak

    :welcome: to iBoats . . . . Is the flex line installed something like this? . . Looks like you got to disconnect the line from the surge brake master cylinder, and then from the closest line coupler on the frame in order to pull the flex line out to replace it . . .

    New ladder install

    :welcome: to iBoats . . . It is your boat, you can do what ever you want. :) You mean this swim ladder on the stern ? . . As you can see, the 'cap' of the boat forms the top of the swim deck. So the swim platform was most likely attached to the swim deck prior to the 2 'halves' of the boat...

    Covid-19 Heat Resistance

    Soooo many quasi-facts rolling around you sort of have to wonder if the blood type stats are considering the population of blood types . . . . . However . . . This video may help understand things . . . . Edit: Extremely funny video removed because of the f-bomb

    2016 Tahoe 400ts ice cooler

    :welcome: to iBoats . . . Why do we always have to do the research :) . . . You mean this cooler? Looks like it is an "Igloo Marine" cooler . . . Might be the "Marine Ultra 36 Quart" . . . hard to tell the exact size, but with a tape measure, you can identify the appropriate model/size. .

    Quick Update . . . The boat is all ready for launch . . . scheduled for tomorrow 8AM. Of course the sea conditions are supposed to be a bit dicey . . . early AM should be better than mid-day. I ran the engines one final time, checked for leaks, etc. and also hooked up the computer (Diacom...

    Automotive HP and torque at cruising speeds

    Not entirely boating related, so I am posting this in the non-boating tech section . . . I have always been curious on how much Horsepower and Torque a car generally takes to drive down the road. Folklore has it as 'not that much' as compared to what most engines are capable of. My mid-size...

    Mercruiser 454 timing chain

    When I re-built my 1991 Merc 454, I think the timing chain was a Mehling brand. You should be able to get all of the parts from the engine industry suppliers rather than through Mercruiser. Here is the original Timing set . . . . Here is the replacement set. I got a lot of parts from Summit...
