    1974 9.9 Johnson running problems. I can get it started but then runs very ruff.

    What did you mean when you said "Extensive Work done", and when was the last Time it was run, prior to the Incident you experienced?

    13x19 Prop Vs 13.2x19

    based on Diameter and Pitch, no difference. However, if there are differences in Blade Area, # of Blades, changes in Rake and/or Cup, there might be a different outcome

    Won't acccelerate

    Some Clarity please: Replaced? As in a New Powerhead? A complete NOS Motor that was sitting in the corner of the Dealer's Warehouse?

    What oil should I use?

    Mercury/Quicksilver offer more than one 10-30 Oil, some are labelled for Outboards, some aren't. The Engine Manufacturers know their Engines and what they require to avoid a Horrible Twitching Death. I know there are some here that will insist that there is No Difference between a Auto/Truck...

    Mid1980's Mercury 2cyl 35hp Spark Plug Question

    There are Much Better Snake Oils than SeaFoam for cleaning the Rings, Merc's Engine Tuner, and BRP's Engine Cleaner, as two. CTC makes a decent one too. Oil should be a Good TCW-3 and mixed at 50:1. Any more is wasting Money, cause if a Bearing is running Smoothly with 50:1, more Oil isn't...

    Won't acccelerate

    If the Dealer can determine you were inside "Tinkering" it could indeed void the Warranty Completely.

    Timing off due to throttle arm and cam follower?

    That cam follower/roller, is supposed to rotate after it comes into contact with the Cam.

    85hp charger speed/prop/rpm concerns

    Just setting the Engine further behind the Transom/Boat, is equal to lowering it. As for the Lower Holes in the Transom, they will be even lower when the Motor is mounted on a Bracket, as the Motor's weight is leveraged. Properly sealed they would not be a Problem in any configuration

    Mercury 115 inline 6 bearing carrier seal issue

    I wasn't asking about the little Roller Bearing. I was asking whether or not the other end of the Carrier had a Friction, or a Non-Friction Bearing. In the Early 80s Mercury changed from a Ball Bearing to a Bushing at that location. I thought it was a Possibility that you have a gearcase from an...

    Lift 1970's 150 Mercury with no power!?

    If I remember correctly, the old Trim System, the one shown in the Pic, only allows the Motor to be tilted up, and once Up, it was there to stay, until a whole bunch of things were done, which involved draining the Hydraulics.

    Mercury 115 inline 6 bearing carrier seal issue

    Marine Engine dot com shows the same Part #s The Seals are different, the Outer one supposedly has some means of fighting/resisting Fishing Lines. You mentioned that the Bearing Carrier, has been superseded. Are you saying you have the Newer Carrier, or the older one? If an older one, I wonder...

    Lower unit gear oil type

    Got to the Dealer, Wally World, Amazon, even Evil bay, and get some Marine Gear Oil, and you won't have to worry about Viscosity. Some on here will Swear and Argue that it is just Auto Gear Oil. I say not. However, it is your motor and money, so you can put whatever you want in it...

    On some of the Yamahas, but on the Merc and OMC 2 strokes, the Carbs are fully Closed, at Idle, and the Timing is used to set Idle speeds

    mercury blackmax 150 power/wot problems

    mercury blackmax 150 power/wot problems

    While the the Idle Timing is what determines the Idle Speed, there is a Specific Screw on the Throttle Linkage that is used for that purpose. Messing with the other screws will likely Eff things up. Throttle Cable Length will also need Adjusting after the Correct Screw is adjusted.

    Is my trailer too short?

    Being that the Bunks are unsupported after the Mount, really isn't much different than just hanging the Transom past the Bunks. On one of my Trailers I installed the Hardware EZ Loader used on a lot of their Trailers to support the Bunks. This Trailer had the Supports at the Transom as OEM, but...
