    89 100hp Mariner compression test

    Going to do a compression check on an 89 100hp Mariner this AM. I understand those are the 2+2 motors and I was wondering if there is anything different about compression checking those as compared to a standard motor. I am not familiar with this system so I was just wondering.

    1982 100hp Mariner

    Going to look at a 1982 100hp Mariner tomorrow and was wondering what peoples feelings are about them. Are parts still available, will mechanics work on them those sort of things, or should I just steer clear and keep looking?

    I have a 1968 aluminum Crestliner Nordic 17' with a 1975, 115hp Merc, at WOT it runs at 30mph (gps) and 4200 rpm with two men in the boat. I don't care that much about increasing the speed but I would like to get the rpm's up closer to max which is 4800 - 5300. The current prop, and I don't know...

    Stiletto Advantage

    I came across a Stiletto Advantage stainless prop in the correct size for my boat but the hub is a 13 spline Johnson or Evinrude. Can I get a different hub kit and convert it to a 15 spline for my old 75 115hp Merc? Thanks

    1975 115hp Merc Hard starting

    I have a 1975 115hp Merc that is hard to start. I have to choke it constantly and it still takes 10-15 attempts. I have the cold idle lever up 3/4 to full and on full choke the entire time. Even after running for 15-20 minutes if we shut it down and fish for 20-30 minutes in order to start it I...

    1975 115hp Merc

    How can I slow the idle on my 75 115hp merc? It idles at 1250-1300 RPM. I can give a little tug on the distributor and it will come down to about 900 but, the next time I rev it up it will stay at 1250 again. Is the idle adjustment part of the link and sync process, which I know nothing about...

    1150 power trim and tilt hoses

    Can someone tell, or show me where each hose connects to the pump unit for the PTT? This is on a 1975 1150 Merc two cylinder system. I know they can really only go two ways which gives me a 50/50 chance, but I don't want to have to take it all apart again after filling and bleeding the system. I...

    1975 Merc 1150 pees on muffs

    I have a 1975 Merc 1150 that I bought last fall. I replaced the impeller, put it on muffs and turned on the water before starting it for the first time today. The pee stream started spraying water even when the motor was not running (not all the time but most of it). On my other Merc's the only...

    Water pump

    I recently purchased a water pump housing kit for my 1975 115hp Merc. It came with the housing, impeller and all of the gaskets and o-rings. My question is: are there seals that goes in the top of the housing to seal around the drive shaft? I always assumed there was and in looking at an old...

    Trim and tilt

    Been wondering about what it would take to add a Merc trim and tilt system to a motor without one. I have a 68, 100 hp Merc and was wondering if it is worth the effort to try and find a working system from another engine and convert it over.I think it would be a great upgrade if it is possible...

    69 100hp grinds when shifting into reverse

    I have a 69 100 hp Merc. I bought the motor for the power head and was told the lower unit would not go into reverse. Not knowing how they work last winter I decided to tear the lower unit down to see if I could spot something that seemed to be a problem and see how the unit worked. Everything...
