    Is Yamaha still building motors for Mercury?

    Is Yamaha still building motors for Mercury? I thought I read that Mercury was going to produce their own motors from now on, but I can't anything about it now.

    Photo/Knowledge of a 1961 Evinrude 10 hp?

    I'm been given a 1961 Evinrude Sportwin 10hp that I won't be taking possession of for quite sometime. I'm curious what it looks like, but the Old OMC site has been down for the last few days and I can't find a photo anywhere. Does anyone know what they look like? More specifically, is it the...

    How to fill 1968 3.9 hp lower unit oil

    I know...stupid question, but the archives search function isn't working properly. I picked up a 1968 Mercury 39 this summer. It had been completely dismantled and repainted (poorly) except for the lower unit. I've got everything back together except the lower unit. However, it is giving me...

    3.9 Merc photos or diagram please.

    I've come over to the dark side or at least the "black" side and bought someone elses headache...a nice little 1968 3.9 hp - in a box. I've pretty much got everything back together, but there are a few little pieces in baggies that I don't know where they go. Would anyone have an exploded...

I understand this is the same gearcase as the 18 hp. anyone know what years will swap with my motor? Any help is appreciated. I don't have a parts manual for...

    Poll - How quick do your old outboards push?

    Performance of old outboards came up in another thread and I thought it might be interesting to see what others are getting for speed out of their old motors. I'm sure my numbers will seem quite small compared to the folks with sea-flees and race boats. I run my kickers on a 1979 12.3' deep and...

    1988 Yamaha 8 hp impeller change

    Just a quick question for you Yammy guys. I'm going to replace an impeller in a buddies 1988 Yamaha 8 hp. Is there anything special about disconnecting the lower unit I should know before I start? I've never worked on Yamaha so I thought I'd ask the pros in this forum.

    1967 3 hp Crankshaft

    Do all the 1952-1967 3 hp motors share the same crankshaft? More specifically, does the 1959 have the same shaft as the 1967? I think they do, but I don't have the parts manual for the 1967 and I don't want to tear two motors apart just to find out that they don't. So much for "Everything is...

    1960 Evinrude 18 hp Fuel Pump Kit

    Anyone know if the factory fuel pump repair kit is still available for a 1960 18 hp? I assume it is, but I can't find one online.

    Vintage Spark Plug Tester

    I'm not sure if this is the right spot for this question. I recently picked up a vintage Champion spark plug tester. It needs some work, but I thought it would look good with the other vintage equipment in my shop. I don't intend to use the sand blaster portion, but I'd like to get it running...

    1983 25 hp Running hot

    I'm having some trouble with a 1983 25 hp. I picked this motor up for parts, but since it only appeared to need a waterpump and spacer bearing I decided to see if I could get it running. It had overheated in the past. I've completely cleaned out every water passage (twice) and installed a new...

    Flywheel Nut Removal/Installation

    Does anyone have a better way of removing/installing a flywheel nut on a 20-35 hp without jamming a bunch of rope into the cylinder? I am really uncomfortable doing that. I cringe everytime I do. I use a strap wrench on smaller motors, but I find it too difficult to hold and turn both wrenches...

    Alternator Kit

    I'd like to add an alternator to my 1988 Johnson 30 hp electric start. Is there an aftermarket kit for this? I'm having trouble finding anything. I find it odd that my parts manual doesn't reference an alternator. How is the starting battery supposed to recharge without one?

    Remove Grease from Lower Unit

    Anyone know if there is a way to remove grease from a lower unit without dismantling it? I should repeat that it is grease and not oil in my lower unit. Doesn't look like any water was in there so I'm not sure why the previous owner switched to grease from oil.

    7.5hp Water Everwhere!

    I replaced the water pump in this motor and found I still wasn't getting circulation. I cleaned out every water passage and port and reassembled everything. I blew air through everything and it seemed fine. I started it up and it pumped fine. Lots of water is pumping out the tell-tale and the...

    1983 25hp Armature support bearing

    I recently picked up a 1983 25hp. The throttle is extremely tight and hard to turn. It appears that the support bearing under the armature is binding. It also looks to be damaged so it should be replaced. Should this part slide freely on the support bracket or am I missing the real problem...

    1969 7.5 hp Merc Parts Diagram

    I'm having some cooling trouble with a 1969 Merc 75. I've pulled this machine completely apart and I'm still not getting circulation. I've replaced the impeller and blown out every tube and port, but I can't find any obstruction. Could be that the pick up tube at the impeller housing is damaged...

    1987 Johnson 20 hp to 30 hp

    I have a 1987 Johnson 20 hp and out of curiosity I decided to see what the difference was between it and the 25/30 hp of the same year since they all share a common block. After pouring over the part numbers for all three motors it would appear that the only difference between the 20 hp and 25...
