    If you live in the USA you can use Amsoil Saber OUTBOARD at ratios from 50:1-100:1 I used it for years, they also have gear lube in a squeeze pak.

    Looking for a prop gasket for 2004 Mercury 8hp

    If it was winterized/storage sealed that could be the oils running out or a poor type of 2cycle oil in the fuel mix.

    Late 60s/early 70s StarCraft 16’ - Mariner OB shifting/idle problems

    The nuts that jam up the throttle and shift cables are loose and aren't locking the cables to the adapters, they might have been turning slowly over the years. Like Waterman said adjustment or cables and from the looks of the box end ones I would say new cables; have you ever greased the control...

    Service mariner 1989 60hp outboard

    "3 - During take out the plate from the carbs I noticed this hose which didn't had anything connected to it." I believe that it is part of the oil/crankcase bleed system, clean the screen and put it back into that hole. If you are going to run it as a constant use motor replace the thermostat...

    Service mariner 1989 60hp outboard

    I'm saying that if you are going to turn the motor with the starter ground the plugs to the block. You can clean the pistons one at a time - when the rings are visible in the exhaust ports, just turn the flywheel.

    Somebody might have undone the bolts instead of using a puller.

    Service mariner 1989 60hp outboard

    If you're going to be turning it over at starting speed to check things put the spark plugs in their boots and ground them to the block - I used a piece of solid copper wire. While the exhaust plate is off you could spray some engine cleaner into the cylinders, the pistons look like they have...

    Trim hoses

    I thought the 1988 models used an integral trim pump/cylinder design which I see online, the hose models were from 1966-1976, maybe you should post a picture.

    Weep hole??

    No part of the fuel system should ever leak fuel out of the system - this is a major fire hazard, I'm guessing there's a leak in the diaphragm or the gaskets. Just do a rebuild.

    Wiring Harness Dislodged 2018 Mercury 115 hp

    Use the serial nr. to find the assembly diagram and maybe it will show an adhesive that they used. It looks like it screws into the motor component.

    1967 merc 60 starter

    It should be lightly greased Merc's 2-4-C is a good choice, some components could be worn out. This is for a later type but the components are the same.

    86' Mercury 150 xr2 V6 pre mixed fuel blowing out of positive pressure ports of crankcase

    Is your altitude above or below sea level? that's normally the reason for changing.

    "and .064 jet added to the main, idle jet .056" Why was this done? Just for my education.

    Mercury inline primary pick up 4-6, which is better, 4 or 6?

    Use the idle stop screw to lower the idle rpm (turn it out to lower). You might have to adjust the cable to bring the distributor to the screw
